There are multiple devices in AR technology, and for example, an AR acquisition device and an AR display device are generally in AR technology.
The AR acquisition device is typically used to acquire images and then transmit the acquired images to the AR display device. And after the AR display equipment processes the image, displaying the image.
Because the acquired image passes through the AR acquisition equipment and then is sent to the AR display equipment for displaying, a certain time delay can be generated in the process.

Based on the same inventive concept, the embodiment of the present disclosure provides a time delay measuring method, which can be executed by any electronic device with computing processing capability.
Fig. 2 shows a flowchart of a delay measurement method in an embodiment of the present disclosure, where the method is applied to an AR acquisition device, and as shown in fig. 2, the delay measurement method provided in the embodiment of the present disclosure may include:
s202, acquiring an image with a time point mark.
It should be noted that the image may include a picture, and may also include a video stream composed in the form of an image.
The image with the time point mark may be such that the image can correspond to a time point.
And S204, sending the image to the AR display equipment so that the AR display equipment determines a first time point according to the time point mark corresponding to the image, and determines the time delay between the AR acquisition equipment and the AR display equipment according to the second time point of the received image and the first time point.
It should be noted that, determining the first time point according to the time point mark corresponding to the image may include: since the AR acquires an image with a time point marker, the AR device can determine a time point corresponding to the time point marker by the corresponding time point marker.
The AR display device records a time point corresponding to the reception of the image when receiving the image.
It should be noted that, after the AR display device obtains the first time point and the second time point, the time delay between the AR display device and the AR acquisition device may be determined according to a difference between the first time point and the second time point.
According to the time delay measuring method provided by the embodiment of the disclosure, the image with the time point mark is obtained, and then the image with the time point mark is sent to the AR display device, so that the AR display device determines the first time point according to the time point mark corresponding to the image, and determines the time delay between the AR acquisition device and the AR display device according to the second time period of the received image. The method comprises the steps of automatically acquiring an image with a time point mark, determining a first time point of the image acquired by the AR acquisition equipment through the image with the time point mark, and determining the time delay between the AR equipment through a second time point of the image acquired by the AR display equipment, so that the automation of determining the time delay of the AR equipment can be realized, and the problem of large error of manually determining the time delay of the AR equipment due to misoperation or inaccurate operation in the process of manually determining the time delay of the AR equipment can be solved.
Based on the same inventive concept, the disclosed implementation provides another time delay measurement method, which can be executed by any electronic device with computing processing capability.
The delay measurement method in the embodiment of the present disclosure is different from the delay measurement method described above in that S202 may include:
as shown in fig. 3, a method for measuring a time delay in an embodiment of the present disclosure may include:
s302, determining a first time point of image acquisition when the image is acquired.
It should be noted that the first time point of acquiring the image includes determining a time corresponding to the image acquisition, that is, the first time point when the image is acquired.
For example, the determining of the first time point of acquiring the image may be performed by the AR acquisition device at the time of acquiring the image, acquiring a time point corresponding to the current time at the corresponding timing device, and then determining the time as the first time point.
And S304, generating a time point mark according to the first time point.
Note that the time point mark may include a time point represented by a number or a time point represented by an image.
Illustratively, after the AR acquisition device determines a first point in time at which an image is acquired, a marker, such as a number or image, that is indicative of the first point in time may be generated.

For example, after determining the first time point, a mark capable of representing an image of the first time point may be generated according to the first time point, and then the mark of the image may be synthesized with the acquired image to generate new image information.
In the embodiment of the disclosure, the first time point corresponding to the time when the image is acquired is determined, and then the time point mark is generated according to the corresponding first time point, so that the AR display device may determine the first time point when the image is acquired according to the time point mark. Therefore, the AR display device can clearly acquire the accurate time for acquiring the image, and the time delay between the AR devices determined based on the time can be more accurate.
Based on the same inventive concept, the disclosed implementation provides still another time delay measurement method, which can be executed by any electronic device with computing processing capability.

as shown in fig. 4, a method for measuring a time delay in an embodiment of the present disclosure may include:
s402, acquiring an image corresponding to a timing interface of the timing equipment.
It should be noted that the timing device may include any device capable of performing accurate timing.
Illustratively, the timing device may include a clock, and any terminal device capable of timing.
For example, the AR capturing device may capture an image of a clock timed in milliseconds when capturing the image, and thus, the AR display device may determine the first time point of capturing the image according to the image of time when determining the first time point.
In the embodiment of the disclosure, an image corresponding to a timing interface is determined by acquiring the timing interface of the timing device, and then the AR display device may determine a first time point corresponding to the acquired image directly according to the image. Therefore, the problem that a procedure is complicated due to the fact that the corresponding relation is established between the acquired first time point and the acquired image can be avoided.

According to the time delay measuring method provided by the embodiment of the disclosure, the image with the time point mark is obtained, and then the image with the time point mark is sent to the AR display device, so that the AR display device determines the first time point according to the time point mark corresponding to the image, and determines the time delay between the AR acquisition device and the AR display device according to the second time period of the received image. The method comprises the steps of automatically acquiring an image with a time point mark, determining a first time point of the image acquired by the AR acquisition equipment through the image with the time point mark, and determining the time delay between the AR equipment through a second time point of the image acquired by the AR display equipment, so that the automation of determining the time delay of the AR equipment can be realized, and the problem of large error of manually determining the time delay of the AR equipment due to misoperation or inaccurate operation in the process of manually determining the time delay of the AR equipment can be solved.
In an embodiment of the present disclosure, the time delay measuring apparatus 700 further includes:
a third determining module 708, configured to determine whether the obtained number of time delays meets a preset number;
a repeating module 710, configured to repeat the foregoing steps until the obtained number of time delays satisfies the preset number when the preset number is not satisfied;
