These drawings and text descriptions are not intended to limit the scope of the present disclosure in any way, but to illustrate the concepts of the present disclosure to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0052] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0053] Before introducing the embodiments of the present application, the application background of the embodiments of the present application is first explained:

[0054] As VR devices become more and more popular, they are gradually entering people's horizons, bringing a lot of convenience to people's work and life. At the same time, people's requirements for VR devices are getting higher and higher. In order to provide users with immersive viewing and gaming experiences, VR devices also need to have higher accuracy and smoother running pictures. Therefore, higher testing requirements are required for VR devices, including testing the two most important operating indicators of VR devices (sensor operating orientation accuracy and picture smoothness).

[0055] At present, the testing of VR equipment mainly involves relevant testers wearing VR equipment and manually testing the various functions of VR equipment, such as wearing VR glasses to watch movies, testing whether there is lag, whether the picture is clear, whether the picture is distorted, etc., so as to obtain the picture synchronization test results. However, the above manual testing process takes a lot of time, has the problems of high labor cost, low efficiency and accuracy.

[0056] In view of the above problems, the invention of this application is as follows: in the process of testing VR equipment, since the rigor of the manual testing process cannot be guaranteed, there is a problem of low test efficiency and accuracy. Based on this, the inventor found that since the high-speed visual camera has the function of simulating the human eye, the picture presented by the VR lens can be shot by the high-speed visual camera to obtain the first video, and the second video can be synchronously obtained by the high-speed camera installed on the VR device, and the second video is used as a standard to determine whether the first video and the second video are synchronized, thereby generating a picture synchronization test result, replacing the manual processing process, which can solve the problem of low test efficiency and accuracy in the prior art, thereby reducing labor costs.

[0057] For example, the VR device testing method provided in the embodiment of the present application can be applied to Figure 1 In the application scenario diagram shown. Figure 1 The following is a schematic diagram of an application scenario of the first embodiment of the test method for VR devices provided in the present application, which is used to solve the above technical problems. Figure 1 As shown, the application scenario may include: a head model 11, a VR device 12 (such as Figure 1 VR glasses as shown), at least one high-speed camera (such as Figure 1 The head mold 11 is provided with a high-speed visual camera, and the VR device 12 includes at least one VR camera (such as Figure 1 VR camera 121, VR camera 122, VR camera 123 and VR camera 124).

[0058] Figure 2 A schematic diagram of an application scenario of Embodiment 2 of the testing method for VR devices provided in the present application, such as Figure 2 As shown, the application scenario may include: a head mold 11 and a VR device 12 , wherein a high-speed visual camera 111 is disposed in the head mold 11 , and the VR device 12 includes a VR lens 125 .

[0059] like Figure 1 and Figure 2 As shown, the target position can be determined in advance according to the preset focal length and the preset field of view, and the high-speed visual camera 111 can be placed at the target position through position calibration to collect VR shooting content in real time. At this time, the picture presented by the VR device 12 shot by the high-speed visual camera 111 is equivalent to the effect of watching VR with the eyes (Note: the content of the left and right eyes of the VR device 12 is the same).

[0060] The VR device 12 can obtain a video through at least one VR camera, and present the video in the VR lens 125 of the VR device 12 for the user to watch. The high-speed visual camera 111 can shoot the video presented in the VR lens 125 to obtain the first video. Similarly, multiple second sub-videos can be synchronously obtained by multiple high-speed cameras, and the multiple second sub-videos can be spliced ​​to obtain the second video.

[0061] Optionally, when the VR device 12 acquires video through at least one VR camera and acquires multiple second sub-videos synchronously through multiple high-speed cameras, the mechanical axis at the bottom of the head mold 11 can be controlled to change at multiple angles so that videos at multiple positions can be acquired, thereby improving the accuracy of subsequent tests.

[0062] Furthermore, the high-speed visual camera 111 can be used with an electronic device ( Figure 1 as well as Figure 2 The first video is sent to the electronic device by the high-speed visual camera 111 and the second video is sent to the electronic device by the VR device 12. The electronic device receives the first video sent by the high-speed visual camera 111 and the second video sent by the VR device 12, and executes the program code of the test method of the VR device to generate a screen synchronization test result.

[0063] exist Figure 1 and Figure 2 In the embodiment shown, the advantage of using four groups of high-speed cameras is that the field of view of the VR camera can be covered synchronously. If a delay problem occurs, the position of the VR camera with the problem can be directly located, thereby providing direction for analyzing the problem.

[0064] It is understandable that the execution subject of the embodiment of the present application may be an electronic device, and the electronic device may be a terminal device, such as a computer, a tablet computer, etc., or a server, such as a background processing platform, etc. Therefore, the present embodiment is explained by collectively referring to the terminal device and the server as an electronic device, and whether the electronic device is specifically a terminal device or a server can be determined according to actual conditions.

[0065] The technical solution of the present application is described in detail below through specific embodiments.

[0066] It should be noted that the following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0067] Figure 3 This is a flow chart of the first embodiment of the testing method for VR equipment provided in the present application. Figure 3As shown, the testing method of the VR device may include the following steps:

[0068] S31, obtaining a first video and a second video.

[0069] The first video includes multiple first sub-videos, and the second video includes multiple second sub-videos.

[0070] Optionally, the multiple first sub-videos in the first video may be a spliced ​​structure, and similarly, the multiple second sub-videos in the second video may also be a spliced ​​structure.

[0071] Optionally, the first video is a video acquired by a high-speed visual camera and a VR camera of a VR device, the high-speed visual camera is used to shoot the picture presented by the VR device, and the second sub-video is a video acquired by a high-speed camera installed on the VR device.

[0072] In a possible implementation, the VR device shoots videos through various VR cameras, stitches the videos shot by various VR cameras, and displays the stitched videos in the lens of the VR device. Furthermore, the high-speed visual camera in the head model shoots the video presented in the lens of the VR device, obtains the first video, and sends it to the electronic device, so that the electronic device receives the first video sent by the high-speed visual camera.

[0073] Similarly, a plurality of high-speed cameras are pre-installed on the VR device, and a plurality of second sub-videos are acquired through the plurality of high-speed cameras. The plurality of second sub-videos are spliced ​​together to generate a second video, which is then sent to the electronic device, and the electronic device thereby receives the second video sent by the VR device.

[0074] Figure 4 Schematic diagram of the first video and the second video provided in the embodiment of the present application. Figure 4 As shown, the first video includes the first sub-video 1, the first sub-video 2, the first sub-video 3 and the first sub-video 4; the second video includes the second sub-video 1, the second sub-video 2, the second sub-video 3 and the second sub-video 4. The first video is a video spliced ​​according to the arrangement position and shooting range of the VR cameras corresponding to the first sub-videos, and the second video is a video spliced ​​according to the arrangement position and shooting range of the high-speed cameras corresponding to the second sub-videos.

[0075] Optionally, the VR device may be a head-mounted VR device, such as VR glasses. It should be understood that the VR device may also be other types of VR devices, which may be determined according to actual conditions, and the embodiment of the present application does not specifically limit the type and model of the VR device.

[0076] Optionally, the installation position of the high-speed camera on the VR device can be determined according to the distribution position of the VR camera of the VR device. For example, Figure 1 The installation position shown is not described in detail here.

[0077] Optionally, the high-speed camera may be a movable high-speed camera.

[0078] Optionally, the total shooting range of multiple high-speed cameras is greater than or equal to the total shooting range of multiple VR cameras, that is, the total coverage area of ​​multiple high-speed cameras is greater than or equal to the total coverage area of ​​multiple VR cameras. This can ensure that the content captured by multiple high-speed cameras and multiple VR cameras is the same, reduce the error of subsequently generated picture synchronization test results, and improve the accuracy of picture synchronization test results.

[0079] S32. Obtain multiple video groups according to the correspondence between the first sub-video and the second sub-video.

[0080] Each video group includes at least one first sub-video and at least one second sub-video.

[0081] Optionally, the correspondence between the first sub-video and the second sub-video may be pre-stored in an electronic device by relevant staff, or may be pre-acquired from a storage device storing the above correspondence.

[0082] Exemplarily, the above correspondence can be represented by Table 1:

[0083] Table 1

[0084] serial number First sub video Second sub video 1 First sub video 1 Second sub video 1 2 First sub video 2 Second sub video 2 3 First sub video 3 Second sub video 3

[0085] Among them, referring to Table 1, it can be known that the first sub-video 1 corresponds to the second sub-video 1, the first sub-video 2 corresponds to the second sub-video 2, and the first sub-video 3 corresponds to the second sub-video 3. According to the above correspondence, three video groups can be obtained, namely, the first sub-video 1 and the second sub-video 1, the first sub-video 2 and the second sub-video 2, and the first sub-video 3 and the second sub-video 3.

[0086] It should be understood that the above-mentioned correspondence may also include other contents and forms, which can be determined according to actual needs, and the embodiments of the present application do not impose specific limitations on this.

[0087] It should be understood that the embodiments of the present application do not limit the number of first sub-videos and second sub-videos in each video group, that is, each video group may include one first sub-video and one second sub-video, or one first sub-video and multiple second sub-videos, or multiple first sub-videos and one second sub-video.

[0088] S33. Generate a picture synchronization test result according to each video in each video group.

[0089] In one achievable manner, a picture synchronization test result is generated according to the target marker and each video in each video group.

[0090] The specific implementation steps and implementation principles of this method can be referred to Figure 5 and Figure 6 The embodiments shown will not be described in detail here.

[0091] In another achievable manner, for any video group, the Hamming distance between image frames at the same time in the first sub-video and the second sub-video is calculated, and a picture synchronization test result is generated according to the Hamming distance and a preset Hamming distance.

[0092] Among them, the picture synchronization test result indicates whether the VR device is visually synchronized, that is, the picture synchronization test result indicates whether the VR device has a delay problem.

[0093] Optionally, when the video group includes multiple first sub-videos or multiple second sub-videos, before calculating the Hamming distance between image frames at the same time in the first sub-video and the second sub-video, the multiple first sub-videos or multiple second sub-videos need to be spliced ​​in a pre-splicing manner.

[0094] The test method of VR device provided in the embodiment of the present application obtains the first video and the second video, obtains multiple video groups according to the corresponding relationship between the first sub-video and the second sub-video, and generates the screen synchronization test result according to each video in each video group. In this technical solution, the first video and the second video replace the manual test process, which improves the efficiency and accuracy of the test, reduces the labor cost, has the advantage of being able to synchronously monitor the screen effect, and can support various models of VR devices.

[0095] Optional, Figure 5 This is a flow chart of the second embodiment of the testing method for VR equipment provided in the embodiment of the present application. Figure 5 As shown, S33 can also be implemented by the following steps:

[0096] S51. For any video group, determine a first target moment when a target marker appears in a first sub-video and a second target moment when a target marker appears in a second sub-video.

[0097] Among them, the target marker can be a calibration object, which can be determined according to actual conditions, and the embodiments of the present application do not impose specific restrictions on this.

[0098] It should be understood that the first sub-video and the second sub-video respectively include a plurality of image frames, and each image frame corresponds to a time moment.

[0099] In one possible implementation, when the target marker appears for the first time in the first sub-video, the current moment is determined as the first target moment. Similarly, when the target marker appears for the first time in the second sub-video, the current moment is determined as the second target moment.

[0100] Among them, the first target time and the second target time can be specific times, such as XXXX year XX month XX day XX hour XX minute XX second XX milliseconds, or a time of the day, such as XX hour XX minute XX second XX milliseconds, or a relative time relative to the start time of the video, such as the first target time is the 3rd second after the start of the video, then the first target time is 3 seconds.

[0101] S52, calculating the time difference between the first target time and the second target time, and generating a screen synchronization test result according to the time difference and a preset time difference.

[0102] Exemplarily, the preset time difference may be 50 milliseconds, or 55 milliseconds, 60 milliseconds, etc., which may be determined according to actual test accuracy, and the embodiments of the present application do not impose any specific limitation on this.

[0103] When the time difference is greater than the preset time difference, a screen synchronization test result is generated, which indicates that the vision of the VR device is not synchronized and there is a delay. When the time difference is less than or equal to the preset time difference, a screen synchronization test result is generated, which indicates that the vision of the VR device is synchronized and there is no delay.

[0104] In the above embodiment, the screen synchronization test result is generated by the target marker, and there is no need to process each image frame in the first sub-video and the second sub-video, which reduces the amount of data to be processed and improves processing efficiency.

[0105] Optional, Figure 6 This is a flow chart of the third embodiment of the test method for VR equipment provided in the embodiment of the present application. Figure 6 As shown, S33 can also be implemented by the following steps:

[0106] S61. For any video group, when a target marker appears in any video in the video group, start calculating the Hamming distance between image frames at the same time in the first sub-video and the second sub-video.

[0107] The Hamming distance between the image frames at the same time in the first sub-video and the second sub-video can be calculated by the existing methods in the prior art, and the embodiments of the present application do not impose specific limitations on this.

[0108] It should be understood that the Hamming distance is used to characterize the similarity between image frames, and the smaller the Hamming distance is, the more similar the image frames are.

[0109] Optionally, when a target marker appears in any video in the video group, assuming that the resolutions of the first sub-video and the second sub-video are different, the resolution of the first sub-video is adjusted to be the same as the resolution of the second sub-video, or the resolutions of the first sub-video and the second sub-video are adjusted to preset resolutions at the same time.

[0110] S62, generating a picture synchronization test result according to the Hamming distance and a preset Hamming distance.

[0111] In a possible implementation, when the maximum value / average value among the multiple Hamming distances obtained is less than the preset Hamming distance, a screen synchronization test result is generated, and the screen synchronization test result indicates that the vision of the VR device is synchronized and there is no delay. Similarly, when the maximum value / average value among the multiple Hamming distances obtained is greater than or equal to the preset Hamming distance, a screen synchronization test result is generated, and the screen synchronization test result indicates that the vision of the VR device is not synchronized and there is a delay.

[0112] In another possible implementation, when all Hamming distances after a preset number are less than a preset Hamming distance, a screen synchronization test result is generated, which indicates that the vision of the VR device is synchronized and there is no delay. Similarly, when any Hamming distance after a preset number is greater than or equal to the preset Hamming distance, a screen synchronization test result is generated, which indicates that the vision of the VR device is not synchronized and there is a delay.

[0113] Exemplarily, the preset number may be 60, 70, 80, etc., which may be determined according to actual conditions, and the embodiments of the present application do not limit this. For example, when all the Hamming distances after the 60th are less than the preset Hamming distance, a screen synchronization test result is generated, and the screen synchronization test result indicates that the visual synchronization of the VR device is not delayed. Similarly, when any Hamming distance after the 60th is greater than or equal to the preset Hamming distance, a screen synchronization test result is generated, and the screen synchronization test result indicates that the visual synchronization of the VR device is not synchronized and there is a delay.

[0114] In the above embodiment, when the target marker appears in any video in the video group, the Hamming distance between the image frames at the same time in the first sub-video and the second sub-video is calculated, and the similarity between the image frames at the same time is judged based on the generated multiple Hamming distances, thereby generating a picture synchronization test result, thereby improving the accuracy of the test.

[0115] Optional, Figure 7 This is a flow chart of the fourth embodiment of the testing method for VR equipment provided in the embodiment of the present application. Figure 7As shown, after obtaining the first video and the second video, the testing method of the VR device may further include the following steps:

[0116] S71. Obtain the frame rate of each first sub-video.

[0117] The number of image frames of the first sub-video may be obtained in each second, thereby obtaining the frame rate of the first sub-video.

[0118] S72. Generate a frame rate test result according to the frame rate and the preset frame rate.

[0119] Optionally, the preset frame rate can be determined according to the actual test accuracy, such as 60 frames per second, 70 frames per second, 80 frames per second, etc., and the embodiment of the present application does not impose any specific restrictions on this.

[0120] In one possible implementation, when the frame rate obtained in S51 is greater than the preset frame rate and greater than or equal to the preset frame rate, a frame rate test result is generated, and the frame rate test result indicates that the first sub-video has a stuttering problem; similarly, when the frame rate obtained in S51 is greater than the preset frame rate and less than the preset frame rate, a frame rate test result is generated, and the frame rate test result indicates that the first sub-video does not have a stuttering problem.

[0121] In the above embodiment, by acquiring the frame rate of each first sub-video and generating a frame rate test result according to the frame rate and the preset frame rate, the manual testing process is replaced, thereby improving the accuracy and efficiency of the test.

[0122] The following is an embodiment of the device of the present application, which can be used to execute the embodiment of the method of the present application.
