Description

  The present invention relates to a competition recording system and a competition video recording method capable of recording the time of each athlete together with the video.

In recent years, attempts have been made to measure individual athletes' times in marathon competitions and the like. For example, a measurement system that measures a competitor's individual time based on the time when a barcode is printed on the athlete's race bib and the reader reads the barcode of the athlete who finished the goal has been put into practical use. .
Nevertheless, since this measurement system reads the barcode over a predetermined time after the goal, the time delayed from the actual measurement was measured in the first place. In particular, when a large number of athletes have scored at the same time, there is a problem that waiting for bar code reading occurs and a time considerably delayed from the actual measurement is measured.
In addition to the goal time, there is an increasing demand to measure the passing time at each time line (intermediate point, etc.), but this measurement system cannot cope with it.

In addition, recently, a technique has been disclosed that can issue a completion certificate in which a measurement time (such as a goal time) is combined with an image of a competitor at the time of a goal (see, for example, Patent Document 1).
Japanese Patent No. 3069723 (page 2-3, Fig. 1)

The timing device disclosed in Patent Document 1 described above generates first set data including a serial number (rank) and a measurement time when a goal judge manually operates a timing switch. The competitors at that time are also filmed. Also, the athlete's number number is identified by OCR or a barcode, and second set data including the serial number and the number number is generated. Further, third set data including a serial number, a race bib number and a measurement time is generated from each set data having the same serial number. Then, the contents of the third set data are combined with the image of the player at the goal time.
In such a time measuring device, the measurement time of the competitor who finishes has already been measured in response to the time switch, so even if many competitors finish the goal at the same time and the identification of the bib number is delayed, there is a delay. The measured time is not measured.

However, if the goal judge misoperates the clock switch, the order of identifying the bib numbers changes, or if the bib numbers are not recognized or duplicated, different bib numbers will be displayed on the competitor's images. There is a possibility that numbers and different measurement times may be combined.
In the first place, the operation of the clock switch was manual, and it was necessary to operate as many as the number of competitors who scored.

  A competition recording system according to an embodiment of the present invention will be described below with reference to the drawings. As an example, a marathon competition will be described as a competition recording system that measures time at a plurality of points.

(Embodiment 1)
FIG. 1 is a schematic diagram showing an example of a configuration of a competition recording system 1 applied to the embodiment of the present invention. In the following description, the relay points and goal points at which time is measured will be collectively described as time points for convenience. That is, the time point indicates a relay point or a goal point. A case where the goal point is different from the start point will be described.

  As shown in the figure, the competition recording system 1 includes a timer console 11, a GPS receiver 12, a wireless communication terminal 13, a time display device 14, a running time transmitter 15, a tag ID receiver 16 installed at the start point, and , A tag console 17, a timer console 11 installed at a timing point (relay point or goal point), a GPS receiver 12, a wireless communication terminal 13, a time display device 14, a running time transmitter 15, a tag ID receiver 16, A tag console 17, a trigger signal generator 18, a measurement time receiver 19, a photographing device 20, a video recording device 21, a data server 22, and a wireless tag 30 carried by each competitor RN. Is done.

A start pistol SP is connected to the timer console 11 at the start point, and a grip switch GS is connected to the timer console 11 at the time point.
In response to the starter operation, the start pistol SP supplies a start signal to the timer console 11 at the start point. Further, the grip switch GS supplies a grip signal to the timer console 11 at the timing point in response to an operation of a time officer or the like.

The timer console 11 is a control unit such as a CPU (Central Processing Unit), a memory such as a RAM (Random Access Memory), a display unit such as an LCD (Liquid Crystal Display), a timer for measuring a running time, and an operation of a keyboard, etc. Part.
The timer console 11 executes time synchronization processing before the start of the competition, and starts measuring the current time synchronized with the standard time received by the GPS receiver 12.

When the start signal is input from the start pistol SP at the start of the competition, the timer console 11 at the start point holds the time as its start time (time information) in its own memory and the wireless communication terminal 13 is controlled to transmit the start time to the timer console 11 at the time point.
On the other hand, when the timer console 11 at the time point receives the start time sent from the wireless communication terminal 13 at the start point, the timer console 11 acquires the start time from the wireless communication terminal 13 and holds it in its own memory. To do.
After holding the start time in its own memory in this way, the timer console 11 sequentially generates a running time based on the difference between the current time measured by its own timer and the held start time. The information is supplied to the time display device 14 as information.
In addition, when a grip signal is input from the grip switch GS, the timer console 11 at the time measuring point supplies the time as grip time (time information) to the video recording device 21 or the like.

  A GPS (Global Positioning System) receiver 12 receives a standard time (GPS time) transmitted from a GPS satellite, and supplies the received standard time to the timer console 11.

The wireless communication terminal 13 is a mobile phone or the like capable of data communication with another wireless communication terminal 13 through a public line (such as a mobile communication network).
Then, the wireless communication terminal 13 at the start point transmits communication data including the start time supplied from the timer console 11 to the wireless communication terminal 13 at the time point.
On the other hand, the wireless communication terminal 13 at the timing point receives the start time sent from the wireless communication terminal 13 at the start point, and supplies the received start time to the timer console 11.

  The time display device 14 includes an electric bulletin board or the like, and displays a running time or the like according to time information sequentially supplied from the timer console 11.

The running time transmitter 15 transmits the running time measured by the timer console 11 to each competitor RN (each wireless tag 30) and appropriately corrects (or sets) the time counted by the wireless tag 30. )
Specifically, the running time transmitter 15 at the start point transmits information including the running time and the threshold value n simultaneously to all the wireless tags 30 immediately after the start. The threshold value n is a value used for the wireless tag 30 to determine the accuracy of the transmitted running time.
The running time transmitter 15 at the start point transmits the running time and the like continuously over a plurality of times (for example, three times or more at intervals of one second) in order to cause the wireless tag 30 to set the time first.
On the other hand, the running time transmitter 15 at the time point is arranged in front of the time line (time line L, which will be described later) as viewed from the traveling player RN, and toward the wireless tag 30 of the player RN located in the vicinity. , Send information including running time.
Note that the running time transmitter 15 at the start point transmits test data such as the current time to each wireless tag 30 for operation confirmation before starting.

The tag ID receiver 16 receives a tag ID returned from the wireless tag 30 in response to the running time transmitted by the running time transmitter 15 (identification information unique to the wireless tag 30). Then, the received tag ID is supplied to the tag console 17.
As with the running time transmitter 15, the tag ID receiver 16 at the time point is also arranged in front of the time line when viewed from the running player RN, and the player RN reaches a measurement zone Z described later. Before, the tag ID returned from the wireless tag 30 is received.
Further, the tag ID receiver 16 at the start point also receives a tag ID returned from the wireless tag 30 in response to test data (current time, etc.) for operation confirmation before starting.

The tag console 17 includes a control unit such as a CPU, a memory such as a RAM, a display unit such as an LCD, and an operation unit such as a keyboard, and manages information transmitted from the wireless tag 30.
The tag console 17 at the start point manages only the tag ID supplied from the tag ID receiver 16, and the tag console 17 at the timing point receives the tag ID and measurement measured from the tag ID receiver 16. The measurement time supplied from the time receiver 19 is also managed.
Specifically, the tag console 17 at the start point confirms the competition start of each player RN from each tag ID acquired after the start. In addition, when the tag ID for the test data is not acquired before the start, the wireless tag 30 that should transmit the tag ID may be out of order or the battery may run out.

Further, the tag console 17 at the timing point appropriately generates a polling list as shown in FIG. 2 in its own memory, and controls the measurement time receiver 19 to receive the measurement time and the like from the wireless tag 30.
Specifically, when the tag console 17 at the timing point acquires the tag ID from the tag ID receiver 16, it registers the tag ID in the polling list shown in FIG. When the tag ID cannot be acquired (the tag ID receiver 16 cannot receive the tag ID), the tag console 17 registers the target tag ID in the polling list by an input from the operation unit. It is also possible.

Then, when the information including the tag ID and the measurement time is sent from the wireless tag 30 of the competitor RN that has passed through the measurement zone Z, the tag console 17 at the timing point receives the measurement time and the like via the measurement time receiver 19. get. The tag console 17 transmits the acquired measurement time to the data server 22 together with the tag ID. After transmitting the measurement time and the like to the data server 22, the tag console 17 deletes the corresponding tag ID from the polling list.
Here, if there is a tag ID that remains without being deleted from the polling list, the tag console 17 controls the measurement time receiver 19 and acquires the measurement time and the like from the target wireless tag 30 by polling reception. If the measurement time or the like cannot be obtained, the tag console 17 generates unpassed person information including the tag ID and transmits it to the video recording device 21. That is, the player RN corresponding to the tag ID is notified to the video recording device 21 as a non-passer, and the measurement time (grip time) is specified (determined).

The trigger signal generator 18 installed at the timing point is installed, for example, toward the timing line L as a timing point from the roadside of the traveling road, and triggers within a predetermined measurement zone Z centering on the timing line L. Send a signal.
As an example, the trigger signal generation device 18 generates a microwave of 24 GHz and transmits a trigger signal toward the measurement zone Z by a predetermined parabolic antenna. Note that the trigger signal generator 18 only needs to be able to obtain the trigger signal directivity and transmit the trigger signal into the measurement zone Z in the same manner. Therefore, even if a communication technique such as UWB (Ultra Wide Band) is applied. Good.

The measurement time receiver 19 installed at the timing point receives the measurement time and the like sent from the wireless tag 30 of the player RN (after passing through the measurement zone Z) located in the vicinity. Further, the measurement time receiver 19 receives the measurement time and the like from the wireless tag 30 by polling according to the control of the tag console 17.
Specifically, the measurement time receiver 19 is controlled by the tag console 17 when the measurement time that should be sent from the wireless tag 30 cannot be received, and the target wireless device 19 is controlled according to the polling list (tag ID remaining without being deleted). The tag 30 is requested to transmit the measurement time, and the measurement time transmitted from the wireless tag 30 in response is received.

The imaging device 20 as an imaging means installed at the timing point is composed of, for example, a video camera or the like, and captures an image of the player RN passing through the timing line L.
Specifically, the imaging device 20 is arranged farther than the trigger signal generator 18 as viewed from the running player RN, and the front (front) of the player RN can be seen so that the bib number, face, etc. of the player RN can be understood. Take a picture. Then, the captured video (video signal) is supplied to the video recording device 21.

The video recording device 21 installed at the timing point is composed of a video recording device or the like, and time data such as grip time and running time supplied from the timer console 11 is added to the video (video signal) supplied from the photographing device 20. Combine (synchronize) and record.
Specifically, as shown in FIG. 3, the video recording device 21 includes a video input unit 21a, a grip time acquisition unit 21b as a passage time acquisition unit, a recording unit 21c as a video recording unit, and a non-passing information acquisition unit. An information acquisition unit 21d, an operation unit 21e, a display unit 21f, a search unit 21g as a search unit, and a registration unit 21h as a registration unit.

The video input unit 21a inputs a video shot and supplied by the shooting device 20.
The grip time acquisition unit 21 b acquires the grip time supplied from the timer console 11.

The recording unit 21c combines and records the grip time acquired by the grip time acquisition unit 21b with the video (video of the player RN) input by the video input unit 21a.
The information acquisition unit 21d acquires unpassed person information supplied from the tag console 17. That is, the non-passer-by information supplied when the tag console 17 cannot receive the polling measurement time from the wireless tag 30 is acquired.

The operation unit 21e inputs a predetermined operation instruction according to the operation of the competition officer or the like.
The display unit 21f not only displays the video input by the video input unit 21a in real time, but also displays a video search screen for causing the search unit 21g to search the video recorded in the recording unit 21c.
For example, when the information acquisition unit 21d acquires unpassed person information, the display unit 21f displays a video search screen including a list of grip times as shown in FIG. 4A, and the operation unit 21e Accept any grip time specified by the competition officials. When the search unit 21g searches for the video, the display unit 21f displays the video of the player RN in which the grip time is synthesized as shown in FIG. 4B.

The search unit 21g searches the video recorded in the recording unit 21c using the grip time designated by the operation unit 21e as a key. That is, the video of the player RN combined with the designated grip time is retrieved (cueing the video) and displayed on the display unit 21f. Here, the competition officer or the like identifies the athlete RN corresponding to the non-passer information (tag ID) by the bib number or the face in the video.
When the video of the player RN searched by the search unit 21g is displayed on the display unit 21f and is specified as the player RN corresponding to the non-passer information (tag ID), the registration unit 21h The combination of the tag ID and the grip time is transmitted to the data server 22 as registration information.

The data server 22 installed at the timing point appropriately acquires data from the tag console 17 and the video recording device 21 and determines the official time and arrival order.
Prior to the start of the competition, when the player information of the player RN, the tag ID of the wireless tag 30 to be used, and the like are input from a predetermined operation unit, the data server 22 stores these information in association with each other. Then, the data is supplied to the timer console 11, the tag console 17, and the video recording device 21 as appropriate.
Further, when registration information for registering the time of a person who has not passed is transmitted from the video recording device 21, the result information and the like are updated, and the official time and the like based on the update result are supplied to the timer console 11.

The wireless tag 30 as a timing device carried by the player RN receives the running time transmitted from the starting time or the running time transmitter 15 at the timing point, and measures the time synchronized with the running time. Then, the trigger signal generated from the trigger signal generator 18 at the timing point is detected, the measurement time in the timing line L is specified, and after passing through the measurement zone Z, the measurement time is transmitted to the measurement time receiver 19. Note that the wireless tag 30 also transmits the measurement time in response to polling from the measurement time receiver 19.
Specifically, as shown in FIG. 5, the wireless tag 30 includes an antenna 31, a receiving unit 32, a time correction unit 33, a timing unit 34, a trigger antenna 35, a trigger detection unit 36, and a time specifying unit 37. And a storage unit 38 and a transmission unit 39.

The antenna 31 is a transmission / reception antenna.
The receiving unit 32 receives the running time transmitted from the running time transmitter 15 through the antenna 31.
Specifically, the receiving unit 32 receives information including the running time and the threshold value n transmitted from the running time transmitter 15 at the start point immediately after the start. At this time, the running time transmitter 15 continuously receives a running time transmitted over a plurality of times (for example, three times or more at intervals of 1 second).
The receiving unit 32 receives information including the running time transmitted from the running time transmitter 15 at the time point.
Then, the receiving unit 32 supplies the received running time and the like to the time correction unit 33.
In addition, the receiving unit 32 receives a measurement time transmission request (polling) from the measurement time receiver 19 at the time point. Then, the received transmission request is supplied to the transmission unit 39.

The time correction unit 33 corrects the running time counted by the timing unit 34 based on the running time received by the receiving unit 32 at the timing point.
Since the running time has not been set in the timing unit 34 until the start of the competition, the time correction unit 33 indicates the running time sent from the running time transmitter 15 at the start point. After receiving three or more times at 1-second intervals, a valid running time is set in the timing unit 34.
At this time, the time correction unit 33 stores the threshold value n sent together with the running time from the running time transmitter 15 at the start point in the storage unit 38.

  When the time difference between the running time received at the timing point and the running time measured by the timing unit 34 is larger than the threshold value n stored in the storage unit 38 at the timing point, the time correction unit 33 Time correction is not performed. This is because, for some reason, the transmitted running time or the received running time may be garbled, etc., so the time correction unit 33 discards the inaccurate running time as it is. To do.

The time measuring unit 34 is appropriately corrected (set) by the time correcting unit 33 and measures the running time synchronized with the running time received by the receiving unit 32.
The timekeeping unit 34 includes a highly stable crystal oscillator, and can stably keep the running time.

The trigger antenna 35 is tuned to the microwave emitted by the trigger signal generator 18 and receives the trigger signal.
The trigger detection unit 36 detects a trigger signal via the trigger antenna 35. Then, the detection result is notified to the time specifying unit 37. For example, the trigger detection unit 36 detects the ON timing of the trigger signal (the timing when the trigger signal is first detected from the state where the trigger signal is not detected) and the OFF timing of the trigger signal (when the trigger signal is detected). The timing at which the detection is finished) is notified to the time specifying unit 37.

The time specifying unit 37 determines the measurement zone Z based on the trigger signal detected by the trigger detection unit 36, and specifies the running time measured by the time measuring unit 34 in the measurement zone Z as the measurement time.
For example, when the athlete RN reaches the measurement zone Z and the ON timing of the trigger signal is notified from the trigger detection unit 36, the time specifying unit 37 uses the running time counted by the time measuring unit 34 as the start time. Store in the storage unit 38. Thereafter, when the player RN passes through the measurement zone Z and the trigger detection unit 36 is notified of the trigger signal OFF timing, the running time counted by the timing unit 34 is stored in the storage unit 38 as the end time. . And the time specific unit 37 calculates | requires the intermediate value of start time and end time, and specifies as the measurement time which the player RN passed the time measuring line L. FIG.
The time specifying unit 37 deletes the start time and the end time from the storage unit 38 and stores the specified measurement time in the storage unit 38.

The storage unit 38 stores the threshold value n received by the receiving unit 32, the measurement time specified by the time specifying unit 37, and the like.
Moreover, the memory | storage part 38 has memorize | stored beforehand unique tag ID different for every radio | wireless tag 30 (every player RN).

When the reception unit 32 receives the running time, the transmission unit 39 transmits the tag ID read from the storage unit 38 to the tag ID receiver 16 as a response. At this time, in order to suppress the occurrence of collision, the tag ID is transmitted at a different response timing determined for each wireless tag 30. In addition, it is possible to use a plurality of wireless channels and to allocate the wireless tags 30 to different channels, thereby suppressing the occurrence of collision.
Further, the transmission unit 39 reads the tag ID and the measurement time from the storage unit 38 and transmits them to the measurement time receiver 19. At this time, the transmission unit 39 may shift the timing in consideration of the transmission of the other wireless tag 30, or may transmit the measurement time or the like in a band of a different channel.
The transmission unit 39 reads the tag ID and the measurement time from the storage unit 38 and transmits them to the measurement time receiver 19 even when the reception unit 32 receives a transmission request (polling) of the measurement time.

Hereinafter, the operation of the competition recording system 1 having the above-described configuration will be described with reference to the drawings.
First, with reference to FIG. 6, the operation from the start of the competition until the tag console 17 at the timing point generates a polling list will be briefly described.

  First, immediately after the start, as shown in FIG. 6A, the running time transmitter 15 at the start point is continuously directed to the wireless tag 30 a plurality of times (for example, three times or more at intervals of 1 second). The running time is transmitted across (T1).

The wireless tag 30 identifies a valid running time from a plurality of running times, and sets the identified running time in the time measuring unit 34 (T2). The wireless tag 30 stores the threshold value n sent together with the running time in the storage unit 38.
Then, the wireless tag 30 transmits its own tag ID to the tag ID receiver 16 as a response to the received running time (T3).

  The tag console 17 at the start point confirms the start of the player RN based on the tag ID received by the tag ID receiver 16.

  Thereafter, when the athlete RN travels to the time point (before the measurement zone Z), the running time transmitter 15 at the time point transmits the running time and the like to the wireless tag 30 as shown in FIG. T4).

The wireless tag 30 corrects the time of the time measuring unit 34 after determining the validity of the received running time (T5).
Specifically, when the wireless tag receives the running time, the wireless tag obtains a time difference from the running time that the wireless tag measures. Then, the calculated time difference is compared with the threshold value n to determine whether or not the running time is accurate.
Here, the wireless tag 30 corrects its running time when the obtained time difference is not larger than the threshold value n (within the threshold value n).
On the other hand, when the obtained time difference is larger than the threshold value n, the wireless tag 30 discards the running time that seems to be inaccurate.
Then, the wireless tag 30 transmits its own tag ID to the tag ID receiver 16 as a response to the received running time (T6).

When receiving the tag ID sent from the wireless tag 30, the tag console 17 at the timing point registers this tag ID in the polling list (T7).
Note that the tag console 17 also registers this tag ID in the polling list when a manual tag ID is input from the operation unit. That is, when the tag console 17 cannot acquire the tag ID (the tag ID receiver 16 cannot receive the tag ID), the clock officer or the like operates the tag console 17 and cannot detect the tag. The ID (tag ID corresponding to the wireless tag 30 of the target player RN) is manually input.

  In this way, a polling list is generated and registered in the tag console 17 before the player RN reaches the measurement zone Z.

  Next, with reference to FIG. 7, the operation of acquiring the measurement time performed by the tag console 17 that has generated the polling list will be described. FIG. 7 is a flowchart for explaining the measurement time acquisition process executed by the tag console 17 at the time point.

First, the tag console 17 at the timing point determines whether or not the measurement time has been received (step S11). That is, the tag console 17 determines whether or not the measurement time or the like sent from the wireless tag 30 when the athlete RN passes through the measurement zone Z is received.
If the tag console 17 at the time point determines that the measurement time has not been received, the process proceeds to step S14 described later.

  On the other hand, when the measurement time is received, the tag console 17 transmits the received measurement time to the data server 22 (step S12). That is, the tag console 17 transmits the acquired measurement time to the data server 22 together with the tag ID.

  The tag console 17 deletes the target tag ID from the polling list (step S13). That is, the tag ID of the wireless tag 30 that has become unnecessary after the acquisition of the measurement time is deleted from the polling list.

The tag console 17 determines whether or not there is a tag ID for which a predetermined time has elapsed since registration in the polling list (step S14). That is, it is determined whether or not there is a tag ID that remains without being deleted from the polling list even after a predetermined time has elapsed.
If the tag console 17 determines that there is no tag ID for which a predetermined time has elapsed, the tag console 17 returns the process to step S11 described above.

  On the other hand, when it is determined that there is a tag ID for which a predetermined time has elapsed, the tag console 17 causes the measurement time receiver 19 to receive the measurement time by polling (step S15). That is, the tag console 17 controls the measurement time receiver 19 to request the target wireless tag 30 to transmit the measurement time.

  The tag console 17 determines whether or not the measurement time has been received (step S16). That is, the tag console 17 determines whether or not the measurement time or the like has been received from the wireless tag 30 by polling.

  When the tag console 17 can receive the measurement time, the tag console 17 transmits the measurement time to the data server 22 and deletes the target tag ID from the polling list (step S17).

  On the other hand, when the measurement time cannot be received, the tag console 17 generates unpassed person information including the tag ID and supplies it to the video recording device 21 (step S18). That is, the player RN corresponding to the tag ID is notified to the video recording device 21 as a non-passer, and the measurement time (grip time) is specified (determined).

Then, the tag console 17 determines whether another tag ID is registered in the polling list (step S19).
If it is determined that there is another tag ID, the tag console 17 returns the process to step S11 and repeatedly executes the processes of steps S11 to S19 described above.
On the other hand, when it is determined that there is no other tag ID, the tag console 17 ends the measurement time acquisition process.

Thus, the measurement time sequentially sent from each wireless tag 30 can be acquired by the measurement time acquisition process performed by the tag console 17 at the timing point. Further, if there is a tag ID that remains without being deleted from the polling list without acquiring the measurement time, the measurement time can be acquired also by polling reception.
Still, when the measurement time cannot be acquired, non-passer-by information is generated and transmitted to the video recording device 21.

  Next, with reference to FIG. 8, a backup operation performed by the video recording apparatus 21 to which unpassed person information can be transmitted will be described. FIG. 8 is a flowchart for explaining a competition video recording process executed by the video recording device 21.

First, the video recording device 21 inputs a video shot and supplied by the shooting device 20 (step S21).
The video recording device 21 determines whether or not the grip time has been acquired (step S22). That is, it is determined whether or not the player RN has passed the time line L and the grip switch GS connected to the timer console 11 has been pressed by a time officer or the like.
If the video recording apparatus 21 determines that the grip time has not been acquired, the video recording apparatus 21 proceeds to step S24 described later.

On the other hand, when it is determined that the grip time has been acquired, the video recording device 21 generates character information indicating the grip time and synthesizes it with the video imaged by the imaging device 20 (step S23).
That is, the grip time is combined with the video of the player RN that has passed through the time line L photographed by the photographing device 20.

  The video recording device 21 sequentially records the videos taken by the imaging device 20 (step S24). At this time, the running time or the like may be combined with the video and recorded.

The video recording device 21 determines whether or not unpassed person information has been acquired (step S25). That is, it is determined whether or not unpassed person information is generated and supplied to the tag console 17 that performs the measurement time acquisition process of FIG. 7 described above.
If the video recording device 21 determines that the unpassed person information has not been acquired, the video recording device 21 advances the processing to step S29 described later.

On the other hand, when it is determined that the unpassed person information has been acquired, the video recording device 21 displays the video search screen as shown in FIG. 4A described above, and accepts any designated grip time (step) S26).
Then, when the grip time is received, the video recording device 21 searches for and displays the video of the player RN in which the designated grip time is synthesized (step S27). That is, the video of the player RN with the combined grip time as shown in FIG. 4B is displayed.
Here, the athlete RN corresponding to the unpassed person information (tag ID) is identified by the race official or the like by the bib number or the face in the video.

In addition, when the video of the competition RN who is searched and displayed is not the competitor RN corresponding to the non-passer information (tag ID), the grip time is received again in step S26, and the competition is performed in step S27. The video of the user RN is retrieved and displayed.
And if it is specified as a player RN corresponding to non-passer information (tag ID) by a race official etc., a registration button as shown in Drawing 4 (a) will be operated, for example. In response to this operation, the video recording device 21 generates registration information in which the tag ID and the grip time are combined, and transmits the registration information to the data server 22 (step S28). When this registration information is transmitted to the data server 22, the result information and the like are updated in the data server 22.

The video recording device 21 determines whether or not the competition has ended (step S29). If it is determined that the competition has not ended, the video recording device 21 returns the process to step S21 and repeatedly executes the processes of steps S21 to S29 described above.
On the other hand, when it is determined that the competition has ended, the video recording device 21 ends the competition video recording process.

Even if the measurement time cannot be received from the wireless tag 30 at the tag console 17 by such a competition video recording process (when the measurement time is missed), the player RN who has not passed is displayed by video. It is possible to confirm and specify the grip time (measurement time).
At that time, by specifying the grip time, it is possible to cue the video of the player RN, and to easily perform the determination work.
As a result, the time of each competitor can be recorded together with the video.

In the above-described embodiment, the case has been described in which the imaging device 20 captures only one imaging area that is a front image of the player RN. However, a plurality of imaging devices 20 are arranged to capture different imaging areas. May be.
For example, as shown in FIG. 9A, the photographing device 20a photographs the photographing area A (the front image of the player RN), and the photographing device 20b photographs the photographing area B (the side image of the player RN). May be.
Then, the video recording device 21 synthesizes and records the grip time supplied from the timer console 11 on these videos.
In this case, it is also possible to determine the advance arrival of the player RN.

Further, as shown in FIG. 9B, for example, the traveling path may be divided into a plurality of zones, and each of the zones may be photographed by the photographing devices 20a to 20n.
Then, the video recording device 21 synthesizes and records the grip time supplied from the timer console 11 on these videos.
In this case, when the course on which the athlete RN runs is divided, each athlete RN can be photographed.

In the above-described embodiment, the case where the running time is transmitted from the running time transmitter 15 toward the wireless tag 30 and the time synchronized with the running time is counted by the timing unit 34 of the wireless tag 30 has been described.
However, what is transmitted from the running time transmitter 15 is not limited to the running time, and other time information may be transmitted. For example, the current time measured by the timer console 11 is transmitted from the running time transmitter 15 to the wireless tag 30, and the wireless tag 30 (timer unit 34) measures the time synchronized with the current time. It may be.

Specifically, the running time transmitter 15 at the start point transmits information including the current time and the threshold value n to all the wireless tags 30 by broadcast before the competition starts. To do. At this time, the running time transmitter 15 transmits the current time and the like continuously over a plurality of times (for example, three times or more at intervals of 1 second).
On the other hand, the wireless tag 30 sets a valid current time in the time measuring unit 34 in consideration of a plurality of current times that should change with time. Then, the threshold value n and the first set time sent together with the current time are stored in the storage unit 38.

When the competition starts and the competitor RN advances to the time point, the wireless tag 30 receives the current time sent from the running time transmitter 15 at the time point. When this current time is received, the wireless tag 30 (time correction unit 33) corrects the time counted by the time measurement unit 34 based on the received current time.
In this case as well, when the time difference between the current time received at the timing point and the time measured by the timing unit 34 is larger than the threshold value n stored in the storage unit 38, the time correction unit 33 Do not make corrections.

Then, the wireless tag 30 detects the trigger signal and stores the specified measurement time in the storage unit 38, and then reads the tag ID and the measurement time from the storage unit 38 in response to spontaneous or polling. Transmit to the receiver 19.
On the other hand, when the tag console 17 acquires these pieces of information via the measurement time receiver 19, the tag console 17 transmits the acquired measurement time together with the tag ID to the data server 22. And the data server 22 specifies the time of each player RN from start time and measurement time.

  In the above embodiment, the case where the start point and the goal point are different has been described as an example. However, the present invention can be similarly applied to the case where the start point and the goal point are the same.

In the above embodiment, the marathon competition has been described as an example, but the competition to be timed is not limited to this and is arbitrary.
For example, the present invention can be applied as appropriate to relay races, racewalking, disabled wheelchair road races, bicycle road races, triathlons, and mountain sports such as running and orientation.

  As described above, according to the present invention, the time of each player can be recorded together with the video.
