Accordingly, the two-dimensional plan view data can be expressed as a three-dimensional image in the virtual three-dimensional space, and even when the position of the monitored object is displayed, it can be displayed at an appropriate position in the plan view data. Here, “features” refers to all objects on the ground, such as artificial things such as buildings and facilities, and non-artificial natural things such as rivers and mountains. Moreover, the plan view data for each height indicates a drawing in which a feature is horizontally sectioned for each predetermined height or a plan view, and can be a floor plan for each floor if it is a facility.

For example, in the case of the first floor sketch G1 shown in FIG. 4A, points P11 to P13 and points K11 to K14 (points P11 and K11 are the same positions) are determined in advance (point setting). Next, the longitude and latitude of the building B corresponding to the points P11 to P13 and the points K11 to K14 and the height of the first floor corresponding to the floor plan G1 are respectively surveyed to obtain survey coordinate data (X coordinate data, Y coordinate data, Z coordinate data) (point surveying). The survey coordinate data is associated with the drawing coordinate data where the points P11 to P13 and the points K11 to K14 of the first floor sketch G1 are located (coordinate plot). For this association, after the image data to be the sketch drawing G1 is read by the CAD software in a predetermined layer, the survey coordinate data at the positions corresponding to the points P11 to P13 and the points K11 to K14 of the sketch drawing G1 are input in another layer. You can do it. In other words, these two layers can be associated by overlapping them. Similarly, even when the plan view data serving as the sketch drawing G1 is CAD data, the CAD data is read in a predetermined layer, and these can be associated by superimposing them with other layers to which the survey coordinate data is input.
By sequentially performing such association on all the floor plans G1 to G4 from the first floor to the rooftop, the input of survey coordinate data regarding the building B is completed.

When a database of building drawing data is constructed in the storage means 34 in this way, the rescue activity support device 3 can be used for rescue activities.
Here, a method in which the plan view display means 35c and the three-dimensional display means 35e functioning as the feature image display device display based on the building drawing data will be described based on the drawings.

  First, the display screen on the display means 33 will be described with reference to FIGS. On the display screen D of the display means 33 shown in FIG. 5, a planar display area AR1 by the plan view display means 35c is arranged on the right side, and a stereoscopic display area AL by the stereoscopic display means 35e is arranged on the left side.

  In the plane display area AR1, three floors from the top floor to the bottom floor are displayed based on the floor plan data of each floor, and the scroll bar SB for displaying the floor plan data of the floor that cannot be displayed is arranged at the right end. Has been.

In the stereoscopic display area AL, plan view data from the first floor to the roof is arranged corresponding to the coordinate system of the virtual three-dimensional space S (see FIG. 6) based on the XY coordinate data and the Z coordinate data, and the virtual tertiary An image in which the height direction of the original space is aligned with the vertical direction of the display screen is displayed.
The Z axis of the virtual three-dimensional space S is adjusted to a scale corresponding to the height of the building B in the height direction of the building B in the height direction of the display screen displayed in two dimensions. The X axis is parallel to the upper and lower sides of the rectangular plan view data in the horizontal direction of the display screen. The Y axis is a depth direction orthogonal to the display screen, and is parallel to the right side and the left side of the plan view data. The X axis and the Y axis are also adjusted to a scale corresponding to the size of the plan view data. In FIG. 5, since the Y axis is in the depth direction orthogonal to the display screen D, the sketch is a two-dimensional line and the conductor cannot see the floor plan. It is shown in an inclined state. In FIG. 6, for the sake of convenience, the virtual three-dimensional space S is displayed based on the perspective one-point perspective method.

  In the three-dimensional display area AL, since the building B is a three-story building with a roof, all four drawings G1 to G4 are displayed. However, in the case of a high-rise building such as the 20th or 30th floor, it cannot be displayed in the stereoscopic display area AL. In that case, the plan bar data of each floor can be observed by moving the displayable range by causing a scroll bar to appear at the right end of the stereoscopic display area AL as in the flat display area AR1.

  In the three-dimensional display area AL, a virtual contour line OL that connects the upper and lower floors of each corner of the building B indicated by the floor plan data of each floor is displayed. In the case of the building B, the virtual contour OL is a line connecting points K11, K21, K31, K41, a line connecting points K12, K22, K32, K42, a line connecting K13, K23, K33, K43, and points K14, K24. , K34, K44. In other words, the virtual contour OL is a line that connects points that are the same XY coordinate data in the height direction.

Here, the coordinate system of the plan view data displayed in the plane display area AR1 and the stereoscopic display area AL will be described based on the drawings.
The building is not designed to match unless the north direction of the survey coordinate system represented by latitude / longitude coincides with the upper direction of the sketch representing the building B. For example, FIG. As shown, it is often in an oblique state with respect to the axial direction indicating latitude and longitude. However, the layouts G1 to G4 (see FIG. 4) showing the buildings are arranged in the vertical direction and the horizontal direction on the drawing in order to fit in the rectangular area. This is the same whether a paper drawing is created by hand or a drawing is created by CAD. Then, when displaying plan view data when a drawing is created by CAD, or plan view data generated by reading a paper drawing with a scanner device, one corner of this rectangular area, for example, the lower left, is a plan view. The data is displayed with the origin of the coordinate system, the horizontal direction as the X axis, and the vertical direction as the Y axis.

  Specifically, as shown in FIG. 8A, when the plan view data showing the floor plan G1 of the first floor of the building B is displayed on the display screen of the display means 33, the coordinate system of the plan view data is displayed. If the display is based on the coordinate axes (X axis, Y axis), the sketch G1 is displayed correctly.

  However, the survey coordinate system based on the latitude and longitude of the points P11 and P12 assigned as two points on a virtual straight line parallel to the vertical direction or the horizontal direction of this sketch is used as the vertical and horizontal directions of the display screen, that is, drawing data. When the mark indicating the monitored person is superimposed on the displayed plan view data, the position of the monitored person is the position on the floor plan G1 and in the actual building B. May be displayed at a different position.

  In the rescue activity support apparatus 3 shown in FIG. 3, the calculation means 35a calculates the correction angle, and based on the correction angle, the rotation means 35b rotates the coordinate axis of the surveying coordinate system based on the coordinate axis of the coordinate system of the plan view data. Let

  That is, a virtual straight line L1 (same as the wall surface W in FIG. 8) connecting the points P11 and P12 indicated by the survey coordinate data (X coordinate data, Y coordinate data) and the longitude direction of the survey coordinate system passing through the point P11 ( In FIG. 8, the inclination of the sketch G1 can be calculated by calculating with the calculation means 35a the correction angle θ as an angle formed with a dotted virtual straight line L2.

This calculation can be calculated by the following equation (1) because the virtual straight line L1 connecting the points P11 and P12 on the sketch drawing G1 is a virtual line parallel to the horizontal direction of the sketch drawing G1.
Correction angle θ = tan ⁻¹ [(Y′−Y) / (X′−X)] (1)
However, the longitude of the point P11 is X, the latitude is Y, the longitude of the point P12 is X ', and the latitude is Y'.

  Next, as shown in FIG. 8B, the rotating means 35b is based on the coordinate axis of the coordinate system of the virtual horizontal plane H (see FIG. 6) where the plan view data is located based on this correction angle θ. The coordinate axes (longitude direction and latitude direction) of the survey coordinate system are rotated and corrected.

Since the coordinate axis of the coordinate system of the virtual horizontal plane H of the virtual three-dimensional space S indicated by the Z coordinate data (floor height data) of the sketch G1 is corrected by the correction angle θ, the coordinate axis is corrected to the virtual horizontal plane H corrected. By arranging the figure data, a display in which the left and right direction of the display screen D and the left and right direction of the sketch G1 and the depth direction of the display screen D and the vertical direction of the sketch G1 are matched can be performed in the stereoscopic display area AL. .
Similarly, for the sketch drawings G2, G3, and G4, the respective plan view data are arranged in the virtual three-dimensional space S. By doing so, the floor plan data corresponding to each floor is displayed in order based on the corrected coordinate axes, so that the three-dimensional display of the display screen D in a state where the directions of the floor plan data of all the floors are aligned. It can be displayed in the area AL.
Also, in the flat display area AR1, the virtual horizontal plane H with the coordinate axis corrected is made to correspond to the two-dimensional plane of the display screen D, and each of the sketches G2 to G4 (the sketches G2 and G3 in FIG. 5) from the sketch G1, respectively. By arranging the plan view data, the plan view data corresponding to each floor is sequentially displayed based on the corrected coordinate axes. Therefore, the display in which the horizontal direction of the display screen D and the horizontal direction of the sketch G1 are matched with the vertical direction of the display screen D and the vertical direction of the sketch G1 can be performed in the flat display area AR1.

  In the present embodiment, the correction angle θ with respect to the horizontal direction of the display screen is calculated as the inclination of the sketch G1 shown in FIG. 7, but for example, the point P13 is on a virtual straight line parallel to the vertical direction of the point P11. By being positioned, the inclination with respect to the vertical direction of the sketch G1 may be calculated.

As described above, the display in which the horizontal direction of the display screen D and the horizontal direction of the sketch G1 are matched with the depth direction of the display screen D and the vertical direction of the sketch G1 can be performed in the stereoscopic display area AL. Can be displayed in the three-dimensional display area AL of the display screen D in the state in which the direction of the plan view data is aligned, so that a rectangular building is displayed diagonally along the diagonal line of the display screen, or the front of the building is displayed. It is possible to prevent a situation where it is difficult to see because the portion facing downward on the screen faces upward.
When the two-dimensional plan view data is displayed in the virtual three-dimensional space in the stereoscopic display area AL of the display screen D, and the plan view data is viewed from the front by the plan view display means 35c in the plane display area AR1. By displaying the above image, the plan view data in a tilted state and the plan view data in a non-tilt state are displayed on the same display screen D, so that it is easy to grasp a sketch at each height. it can.

In the display screen D shown in FIG. 5, the plane display area AR1 by the plane view display means 35c is displayed on the right side. However, instead of the plane display area AR1, as shown in FIG. You may make it display image | video MV by 35d.
The video MV by the video display means 35d is transmitted by the imaging means 24 of the position communication device 2 carried by the rescuer who is the monitored object. The video display means 35 d receives the video from the position communication device 2 via the wireless means 31 and displays it on the display screen D of the display means 33. By doing so, the situation of the site where the rescuer is working can be grasped in more detail.
FIG. 9 shows an example in which the rescuer R is imaging from the position indicated by the mark M1 or the mark M2 toward the corner KD of the room. The video MV is not limited to a moving image but may be a still image that is periodically captured.

The moving direction display means 35j calculates the moving direction of the rescuer R from the longitude position data and the latitude position data at two positions before and after the current position and the previous position from the position communication device 2. This moving direction can be calculated by a general straight line formula (formula (2)) passing through two points. However, the two points indicated by the two longitude position data and the latitude position data transmitted from the position communication device 2 are (X ₁ , Y ₁ ) and (X ₂ , Y ₂ ).
_{y = (Y 2 -Y 1)} / (X 2 -X 1) × (x-X 2) -Y 2 ····· (2)
Then, the movement direction display means 35j displays the calculated movement direction on the display means 33 by superimposing the calculated movement direction on the plan view data of the virtual three-dimensional space S displayed in the stereoscopic display area AL. By doing so, the direction in which the rescuer R is moving can be easily grasped. Moreover, if the video MV is displayed in the video display area AR2, the direction in which the image is captured can be easily grasped.

  Next, based on the position data (longitude position data, latitude position data, height position data) included in the notification received from the position communication device 2 via the wireless means 31, the position display means 35g is adjusted to the corrected coordinate axis. Based on the plan view data. At this time, a mark indicating the position of the rescuer R, who is the monitored object, is superimposed on the plan view data corresponding to the floor on which it is located. The position display means 35g of the display control means 35 superimposes a mark M1 (see FIG. 5) indicating the position of the rescuer R on the plan view data, so that the conductor is located in the building B. Can be understood at a glance. When superimposing the mark M1 on the floor plan data corresponding to the floor where the mark M1 is located, the height determination means 35f specifies the position where the rescuer R is located based on the height position data from the position communication device 2, and displays the position. The means 35g superimposes on the corresponding plan view data.

  It is also possible to superimpose a mark indicating the position of the rescuer R according to the height position data. The position display means 35g superimposes a mark M2 (see FIG. 5) indicating the position of the rescuer R according to the height position data, so that the plane of the floor where the rescuer R is located is superimposed. Since the mark M2 is displayed between the figure data and the floor plan data on the upper floor, the location of the rescuer R can be grasped three-dimensionally. When superimposing the mark M2 according to the height position data, the position display means 35g superimposes the mark M2 at a height corresponding to the Z axis of the virtual three-dimensional space S based on the height position data from the position communication device 2. Let By displaying the mark M2 based on the height position data, for example, when the rescuer is located between the lower floor and the upper floor (between the plan data in the vertical direction) on a staircase or an elevator, When the administrator wants to clearly recognize the position of the rescuer, it can be easily and accurately grasped.

  In this way, the mark M1 or the mark M2 indicating the position of the rescuer R that has entered the building B is superimposed on the sketch drawing G1. When a rescue operation is performed by a plurality of rescuers, a plurality of marks can be displayed by displaying according to the identification information from the identification information transmission means 23 of the position communication device 2. When carrying out rescue activities, the fire brigade acts as a pair of rescuers and organizes the two groups as one team. There are two teams in the medium-scale fire brigade and more teams in the large-scale fire brigade. Therefore, although the number of rescuers entering depending on the scale of the fire is different, at least two rescuers will enter, so when the rescuer enters the building B, the position of each rescuer is commanded. It is desirable to be able to grasp.

  In the example shown in FIG. 5, the mark M <b> 1 or M <b> 2 indicating the rescuer R is indicated by “●”. However, when two or more rescuers enter, the identification assigned to each position communication device 2 By preserving the correspondence between the information and the rescuer R, each rescuer R is made into a star (☆), double circle (◎), triangle (▲ or ▼), etc. from the outside. It is possible to easily determine the positions of a plurality of rescuers R in the building B which is difficult to understand.

  In this way, the display control means 35 functioning as a feature image display device generates plan view data indicating the floor plan of each floor of the building based on the XY coordinate data and Z coordinate data of two points on the plan view data. Since they are arranged in the coordinate system of the virtual three-dimensional space S, they can be arranged three-dimensionally without relatively shifting the floor plan data of each floor. Therefore, even when the position of the rescuer R is indicated by the mark M1 or M2, it can be displayed at an appropriate position in the plan view data. Therefore, the rescue activity support apparatus 3 according to the present embodiment can easily grasp the rescuer R as the monitored body and accurately grasp the position of the rescuer R by expressing the building three-dimensionally. be able to.

Next, when the sketch drawings G1 to G4 are displayed horizontally along a plane in the stereoscopic display area AL, the floor plan G1 to G4 cannot be confirmed because it looks like a two-dimensional line. When it is desired to change the display inclination angle of the plan view data, it can be changed by operating a predetermined key (for example, a cursor key) of the input means 32.
For example, an up arrow key that is one of the cursor keys is pressed. The time during which the up arrow key is pressed is the amount of change. As shown in FIGS. 10A and 10B, the tilt display means 35h uses the virtual straight line Lx passing through the center point O of the floor plan data on each floor as the rotation axis while the up arrow key is pressed. , Tilt each plan view data. That is, the front side of the plan view data as the sketch drawings G1 to G4 is lowered and the back side is raised. By tilting the respective plan view data corresponding to each floor, the plan view data can be tilted in a direction that is easily visible to the conductor.
For example, when the position of the rescuer R is displayed as the mark M2 in FIG. 5, the position of the rescuer R can be grasped more by observing the input means 32 while adjusting the display inclination angle of the plan view data. Can be easy and effective

  When the floor plan data of each floor is excessively inclined, the down arrow key is pressed. By doing so, the inclination display means 35h, on the contrary, raises the front side of the plan view data and lowers the back side. In this way, the display inclination angle of the plan data of each floor can be adjusted.

  In the present embodiment, the virtual straight line Lx passing through the center point O of each plan view data is inclined as the rotation axis. However, if it is a virtual straight line on each plan view data, it may not be the center point O. It may be a virtual straight line that overlaps the front end side of the plan view data or a virtual straight line that overlaps the rear end side. The virtual straight line is preferably a straight line parallel to the display screen D because it is easy to observe when the plan view data is tilted. In addition to tilting the plan view data with the virtual straight line as the rotation axis, the entire virtual three-dimensional space S may be tilted forward or tilted forward.

  As described above, according to the rescue activity support apparatus 3 according to the present embodiment, it is possible to display the building drawing data in a state that is easy to see for the conductor using the plan view data indicating the floor plan of the building. In particular, the plan data serving as the basis of the building drawing data has a wide range of use because image data can be adopted by reading a paper drawing of a building with a scanner device as well as drawing data drawn by CAD. In order to share information with local fire departments and other related organizations and to carry out quick rescue activities, the fire department headquarters sends the building's CAD data to educational institutions such as facilities and schools where care recipients are located. Is requested. However, it is possible to provide CAD data if it is newly constructed, but in the case of what was previously constructed, it is actually provided by paper drawings. That is, most are not digitized. Even in such a state, the rescue operation support device of the present invention uses the sketch data provided by the paper drawing by the scanner device as the plan data, and performs the rescue activity based on the plan data. By supporting, it can contribute to local fire fighting activities.

  In the present embodiment, building drawing data of a nursing facility is stored in the storage unit 34 in the rescue activity support device 3. Since each of the plan view data stored as the building drawing data is two-dimensional drawing data, the data amount is smaller than that of the three-dimensional solid drawing data. Accordingly, since the transfer time is short, the building drawing data is stored in the storage means of the computer installed in the fire department headquarters H1 or the fire department H2, and the fire truck C equipped with the rescue operation support device 3 is dispatched. While moving, the building drawing data relating to the building that became the fire site may be transmitted from a computer installed in the fire headquarters H1 or the fire station H2 via the telecommunication line NW.

  In the rescue activity support system 1 according to the present embodiment, a mobile phone is used as the position communication device 2. However, in GPS positioning in a building, the GPS signal from the satellite is significantly attenuated. Therefore, there is a possibility that it cannot be received well. In that case, it is possible to specify the position of the rescuer R with higher accuracy by using HGPS (High Sensitivity GPS) and AGPS (Assisted GPS). In addition to the GPS, the position of the rescuer R can be specified by a wireless LAN method, various tag methods, an LED method using light, an ultrasonic method, or the like. In the present embodiment, the position communication device 2 is a mobile phone carried by the rescuer R who is a monitored person. However, the position communication device 2 may be a device attached to an article to manage physical distribution, It can be built into a robot to guard the inside.

  In the present embodiment, a single nursing care facility has been described as an example of the building B. However, the present invention is also applicable to a facility in which a plurality of buildings are individually arranged in the site, such as a plant, a factory, or a large-scale shopping mall. It is possible.

  Furthermore, in the display screen D of FIG. 5, when the Y axis is a depth direction orthogonal to the display screen, the sketch is a two-dimensional line, and the entire three-dimensional virtual space S is inclined in advance from the initial display. As shown in FIG. 10B, the plan view data may be displayed in a state where each plan view data is individually inclined. The image in the virtual three-dimensional space S may be a display image by perspective.

The present invention is suitable for a rescue operation support device for instructing and supporting a rescuer's rescue operation from outside the facility in a situation where it cannot easily enter the facility due to a fire or disaster, Safety management support device that performs safety management by grasping the positions of employees and workers who work in facilities such as chemical factories, monitored personnel such as entering and exiting hazardous areas, and the position of robots that move within the factory It is suitable for a production management support device that detects a flow and performs flow line management, or monitors a flow of a product (product) or a raw material, and an article management support device for a product stored in a warehouse.
Moreover, the present invention can be used as a facility in a zoo, a shopping mall, an exhibition room of a museum, etc., as well as a hospital, a care facility, a factory, etc. where care recipients are located. In that case, it is possible to detect the degree of popularity, the traffic line of the spectator / shopper, and conduct a dynamic survey by bringing the mobile phone with GPS function as a position communication device to the spectator or shopper. In addition, the monitored object may be not only a rescuer that is a moving body but also an article that does not move. By doing so, the rescue activity support device functioning as a position detection device can be applied as an article management device such as warehouse management and inventory management.
Furthermore, by arranging cross-sectional views and plan views of natural objects such as mountains, rivers, and coasts at predetermined heights in the virtual three-dimensional space S as plan view data and displaying them on the display screen, the shapes of the mountains and rivers can be displayed. It becomes easy to grasp, and the location and movement of a person or an object can be easily grasped.
