[0022] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0023] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0024] The main solution of this application is to obtain simulation data and a first simulation video after the production of the whole vehicle project software starts. The simulation data is recorded in the simulation instrument function of the old version of the instrument software. The first simulation video is recorded in the process of simulating the instrument function of the old version of the instrument software to obtain the simulation function in the new version of the instrument software based on the simulation data, and the simulation process is recorded into a second simulation video; the first simulation video and the second simulation video are compared to generate a consistency test report.

[0025] At present, the mainstream is to use automated or manual methods for testing, but the development time of automated use cases in this method is long, resulting in low efficiency of automotive instrument function testing. Therefore, how to improve the efficiency of automotive instrument function testing is a problem that still needs to be solved.

[0026] This application generates a consistency test report by comparing videos of automobile instrument software tests, thereby improving the efficiency of automobile instrument function testing.

[0027] Based on this, the embodiment of the present application provides an instrument testing method based on data playback video comparison, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the instrument testing method based on data playback video comparison of the present application.

[0028] In this embodiment, the instrument testing method based on data playback video comparison includes steps S10 to S30: Step S10: after the vehicle project software starts production, obtaining simulation data and a first simulation video, wherein the simulation data is recorded in the simulation instrument function of the old version instrument software, and the first simulation video is recorded in the process of the simulation instrument function of the old version instrument software; It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, an instrument test device based on data playback video comparison, etc. The following takes the instrument test device based on data playback video comparison as an example to illustrate this embodiment and the following embodiments.

[0029] It should be noted that after the vehicle project software SOP, the software status tends to be stable. As an indispensable functional component of the vehicle, the instrument has its functions frozen. However, in order to meet a better functional experience, the entire cockpit software will have continuous OTA iteration and optimization needs. As a module in the cockpit software delivery, the instrument needs to be tested and covered even if no changes have occurred to ensure the quality of the entire software delivery. The test is to see if the instrument function is affected after the OTA iteration. Therefore, the main test content is to detect whether the instrument function has changed compared to before the OTA iteration. The instrument test can be completed quickly by comparing the data playback video.

[0030] It is understandable that before testing, a test environment with video and analog signals needs to be built on the local side of the instrument.

[0031] In a feasible manner, the steps of obtaining the simulation data and the first simulation video, wherein the simulation data is recorded in the simulation instrument function of the old version of the instrument software, and the first simulation video is recorded in the process of the simulation instrument function of the old version of the instrument software, include: According to the instrument's functional module use case, use the test equipment in the old version of the instrument software to simulate the triggering of the instrument function; Get simulation data during instrument function simulation; A first simulation video is obtained by recording a simulation process of an instrument function.

[0032] It should be noted that the functional modules of the instrument usually include indicator light information, pop-up window and alarm information, gauge information, driving information, infotainment interaction information, charging and discharging information, constant display information, and Advanced Driver Assistance Systems (ADAS) information. During testing, use cases can be designed according to the functions of the instrument. Use cases for some functions can be designed for testing at one time, or use cases for all functions can be designed for batch testing. Simulation data is the data input into the old version of the instrument software during simulation.

[0033] In a feasible manner, the step of using a test device to simulate triggering an instrument function in an old version of the instrument software according to a use case of the instrument's functional module includes: According to the function module use case of the instrument, using the test equipment to generate the signal of the function module use case; This signal is used to simulate the triggering of instrument functions in older instrument software.

[0034] It is understandable that after designing the function module use case of the instrument, it is necessary to use the test equipment to generate the signal of the function module use case and simulate the triggering of the instrument function in the old version of the instrument software through the signal.

[0035] Step S20: simulating the instrument function in the new version of the instrument software according to the simulation data, and recording the simulation process into a second simulation video; It is understandable that after having the simulation data, you can perform simulation tests on the new version of the instrument software and record the simulation process into a second simulation video. Since the simulation data is obtained by testing on the old version of the software, if the instrument functions normally, the instrument display in the second simulation video should be consistent with that in the first simulation video.

[0036] In a feasible manner, the step of simulating the instrument function in the new version of the instrument software according to the simulation data includes: Inject the simulation data into the new version of the instrument software using the test equipment; Based on the simulation data, the instrument functions are simulated in the new version of the instrument software in the same format and sequence as when the old version of the software was tested.

[0037] It is understandable that in order to ensure data consistency, the instrument functions need to be simulated in the same format and sequence as when the old version of the software was tested.

[0038] Step S30: performing a video comparison between the first analog video and the second analog video to generate a consistency test report.

[0039] It is understandable that the first simulation video is compared with the second simulation video to determine whether the display content of the instrument in the old version of the instrument software is the same as the display content of the instrument in the new version of the instrument software. A consistency test report can be generated based on the comparison result.

[0040] In a feasible manner, before performing a video comparison between the first analog video and the second analog video and generating a consistency test report, the method further includes: Noise reduction and color correction are performed on the first analog video and the second analog video to obtain clear and accurate first analog video and second analog video.

[0041] It is understandable that in order to ensure the correctness of the video comparison, the first analog video and the second analog video need to be subjected to noise reduction and color correction to reduce errors.

[0042] In this embodiment, after the production of the whole vehicle project software starts, simulation data and a first simulation video are obtained, the simulation data are recorded in the simulation instrument function of the old version of the instrument software, the first simulation video is recorded in the process of simulating the instrument function of the old version of the instrument software, the instrument function is simulated in the new version of the instrument software according to the simulation data, and the simulation process is recorded into a second simulation video; the first simulation video and the second simulation video are compared to generate a consistency test report.

[0043] In summary, this embodiment generates a consistency test report by comparing videos of automobile instrument software tests, thereby improving the efficiency of automobile instrument function testing.

[0044] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 2 , step S30 also includes steps S301~S302: Step S301: parsing and comparing the first analog video and the second analog video to obtain differences between the first analog video and the second analog video; It is understandable that after obtaining the first analog video and the second analog video, it is necessary to parse the analog video, obtain the video content and compare them, and obtain the difference between the first analog video and the second analog video.

[0045] In a feasible manner, the step of parsing and comparing the first analog video and the second analog video to obtain the difference between the first analog video and the second analog video includes: Extracting the first analog video and the second analog video frame by frame to obtain a first static image and a second static image; Key features of the first static image and the second static image are extracted and compared respectively to obtain differences between the first analog video and the second analog video.

[0046] It is understandable that in order to obtain the differences between the first analog video and the second analog video, the first analog video and the second analog video can be extracted frame by frame respectively, and the first analog video and the second analog video can be converted into a first static image and a second static image respectively, and then the key features of the first static image and the second static image can be extracted and compared to obtain the differences between the first analog video and the second analog video.

[0047] Step S302: Generate a consistency test report according to the difference points.

[0048] It is understandable that a consistency test report can be generated based on the difference points, and in the consistency report, the difference between the first simulation video and the second simulation video can be pointed out. According to the consistency test report, it can be concluded whether the instrument functions normally after the project software is updated.

[0049] In this embodiment, the first analog video and the second analog video are analyzed and compared to obtain differences between the first analog video and the second analog video; and a consistency test report is generated according to the differences.

[0050] In summary, this embodiment generates a consistency test report by video comparison, which can quickly test whether the instrument function is normal, thereby improving the efficiency of automobile instrument function testing.

[0051] For example, in order to help understand the implementation process of the instrument testing method based on data playback video comparison obtained by combining this embodiment with the above-mentioned embodiment 1, please refer to Figure 3 , Figure 3 A brief flow chart of an instrument test method based on data playback video comparison is provided, specifically: the consistency confirmation of two versions of software is completed by video comparison, by simulating the required signals displayed by each module of the instrument on the basic software, recording the display video of the instrument and the simulated data at the same time, and then replaying the data injected by the corresponding module on the new software, recording the video display of the new software, and confirming the consistency by comparing the display status of the two videos. The detailed steps are firstly to inject data into the instrument software A by the test equipment, wherein the injected data is to trigger the function of the instrument, and the display content of the instrument is recorded to obtain video A; then extract the data injected into the instrument software A, and replay the data in the instrument software B by the test equipment, trigger the instrument function, and record the display content of the instrument to obtain video B; finally, compare video A and video B to generate a consistency report.

[0052] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the instrument testing method based on data playback video comparison of the present application.
