[0031] With the rapid development of the automobile industry, in order to ensure the normal operation of the automobile or provide a basis for automobile maintenance, testing the comprehensive performance of the automobile is an indispensable process.
[0032] At present, comprehensive performance testing of automobiles usually involves performing performance tests on the vehicle, obtaining performance test results, and determining the comprehensive performance of the vehicle based on the performance test results. However, the performance test results are usually data or pictures, and non-technical personnel cannot intuitively observe the performance of the vehicle only through data or pictures. Therefore, a method for intuitively observing vehicle test performance is urgently needed.
[0033] In the present application, a vehicle performance testing method is provided. The present application also relates to a vehicle performance testing device, a computing device, and a computer-readable storage medium, which are described in detail one by one in the following embodiments.
[0034] Figure 1 A flow chart of a vehicle performance testing method provided according to an embodiment of the present application is shown, which specifically includes the following steps:
[0035] Step 102: Obtain vehicle parameters and test scenario parameters of the vehicle to be tested.
[0036] When there is a need to perform performance testing on a vehicle, vehicle performance parameters and test scenario parameters of the vehicle to be tested are obtained.
[0037] Specifically, vehicle parameters refer to parameters of vehicle attribute performance, for example, vehicle parameters include vehicle appearance and vehicle configuration, where the vehicle appearance may include vehicle color, vehicle tire model, vehicle A-pillar width, etc., and vehicle configuration may include vehicle 0-100-meter acceleration parameters, vehicle rigidity, etc. Test scenario parameters refer to entity parameters required for the test scenario, for example, the vehicle collision test scenario includes the location and size of obstacles, the area of the test scenario, etc.
[0038] The implementation method for obtaining the vehicle parameters and test scenario parameters of the vehicle to be tested may be to obtain them from a first database storing vehicle parameters and a second database storing test scenario parameters based on a preset parameter acquisition identifier; or it may be possible to open a parameter upload channel for users to input parameters through the front end, and have the users upload the vehicle parameters and test scenario parameters of the vehicle to be tested through the parameter upload channel on the front end.

[0040] Step 104: Based on the vehicle parameters and the test scenario parameters, a performance test is performed on the vehicle to be tested to obtain a performance test result of the vehicle to be tested.
[0041] Specifically, the performance test results refer to the test results of vehicle performance. The performance test results can characterize the performance of the vehicle. For example, in a vehicle collision test scenario, the performance test results can be the collision degree of the vehicle and the collision degree of the obstacle collided by the vehicle, etc. In a vehicle 100-meter acceleration test scenario, the performance test results can be the speed change of the vehicle's 100-meter acceleration, the speed of the vehicle at 100 meters, the degree of deformation of the window, etc.
[0042] There are many ways to perform performance testing on the vehicle to be tested based on vehicle parameters and test scenario parameters and obtain performance test results of the vehicle to be tested. The specific implementation method is determined according to actual conditions and is not limited in this application.
[0043] In a possible implementation of the present application, a performance test is performed on a vehicle to be tested based on vehicle parameters and test scenario parameters to obtain a performance test result of the vehicle to be tested. This may be by building a vehicle test scenario model based on the test scenario parameters, building a vehicle model to be tested in the vehicle test scenario model based on the vehicle parameters, generating a test scenario model, and driving the vehicle model to be tested in the test scenario model to obtain a performance test result, wherein the vehicle model to be tested is a virtual three-dimensional model of the vehicle to be tested, and the vehicle test scenario model is a virtual three-dimensional model corresponding to the test scenario parameters.
[0044] In another possible implementation of the present application, a performance test is performed on the vehicle to be tested based on vehicle parameters and test scenario parameters to obtain a performance test result of the vehicle to be tested. The vehicle parameters and test scenario parameters can be input into a vehicle performance test model to obtain a performance test result of the vehicle to be tested.
[0045] Specifically, the vehicle performance test model refers to an application program / platform, etc., which performs performance testing on the vehicle to be tested.
[0046] Optionally, the vehicle performance test model may correspond to a test scenario. For example, if the test scenario is a vehicle collision test scenario, the vehicle performance test model is an application / platform for testing the vehicle collision performance.
[0047] Optionally, the vehicle parameters and test scenario parameters are input into the vehicle performance test model to obtain the performance test results of the vehicle to be tested. The implementation method is different based on the different settings of the vehicle performance test model. The specific selection is made according to the actual situation and this application is not limited here.
[0048] In one possible implementation of the present application, vehicle parameters and test scenario parameters are input into a vehicle performance test model to obtain a performance test result of the vehicle to be tested. The vehicle parameters and test scenario parameters are input into a vehicle performance test model to generate a target vehicle performance test model, and a performance test is performed on the vehicle to be tested based on the target vehicle performance test model to generate a performance test result of the vehicle to be tested.
[0049] In another possible implementation of the present application, vehicle parameters and test scenario parameters are input into a vehicle performance test model to obtain a performance test result of the vehicle to be tested. Based on the test scenario parameters, a vehicle performance test model corresponding to the test scenario parameters is obtained, and the vehicle parameters are input into the vehicle performance test model to obtain a performance test result of the vehicle to be tested.
[0050] Optionally, based on the different file structures of the performance test results of the vehicle to be tested, the vehicle parameters and the test scenario parameters are input into the vehicle performance test model, and the performance test results of the vehicle to be tested are also different. In one possible implementation method, the vehicle parameters and the test scenario parameters may be input into the vehicle performance test model, and the output results obtained may be converted into a format according to the file format of the vehicle parameters and the test scenario parameters to obtain the performance test results of the vehicle to be tested. In another possible implementation method, the vehicle parameters and the test scenario parameters may be input into the vehicle performance test model, and the output results obtained may be converted into a format according to a preset file format to obtain the performance test results of the vehicle to be tested.
[0051] By applying the solution of the embodiment of the present application, vehicle parameters and test scenario parameters are input into the vehicle performance test model to obtain the performance test results of the vehicle to be tested, so that the obtained performance test results are generated by the vehicle test performance model, so that subsequent mapping processing can be performed based on the performance test results, so that users can intuitively view the performance test results.
[0052] Optionally, the above step of inputting vehicle parameters and test scenario parameters into a vehicle performance test model to obtain a performance test result of the vehicle to be tested includes the following steps:
[0053] Inputting vehicle parameters and test scenario parameters into a vehicle performance test model to obtain an output result of the vehicle performance test model;
[0054] The output results are restored to the intermediate code file of program compilation to obtain the performance test results of the vehicle to be tested.

[0057] The output result is restored to the program compilation intermediate code file to obtain the performance test result of the vehicle to be tested. The implementation method can be based on the program compilation intermediate code file template, the output result file is compared with the program compilation intermediate code file template, and based on the comparison result, the output result of the program compilation intermediate code file is generated and determined as the performance test result of the vehicle to be tested.
[0058] By applying the solution of the embodiment of the present application, vehicle parameters and test scenario parameters are input into a vehicle performance test model to obtain the output results of the vehicle performance test model, and the output results are restored to a program compiled intermediate code file to obtain the performance test results of the vehicle to be tested, so that corresponding mapping processing can be performed based on the restored test results to improve the intuitive display effect of the test results.
[0059] In actual applications, the performance test results of the vehicle to be tested are obtained in the form of data, and the performance of the vehicle to be tested cannot be intuitively observed through the performance test results. To solve the problem of not being able to intuitively view the performance, the following steps are performed based on the virtual space parameters of the target virtual reality device to map the performance test results to the target virtual reality device and generate a performance test animation corresponding to the vehicle to be tested.
[0060] Step 106: Based on the virtual space parameters of the target virtual reality device, the performance test results are mapped to the target virtual reality device to generate a performance test animation corresponding to the vehicle to be tested.
[0061] Specifically, the virtual space parameters refer to the reference parameters when mapping data to the target virtual reality device, such as visual parameters, interaction parameters, etc. The target virtual reality device refers to the device that displays the data intuitively, such as a VR device, an AR device, etc.
[0062] The performance test results may be mapped to the target virtual reality device based on the virtual space parameters of the target virtual reality device to generate a performance test animation corresponding to the vehicle to be tested. The performance test results may be converted to the virtual space dimensions of the target virtual reality device based on the virtual space parameters of the target virtual reality device, and a performance test animation corresponding to the vehicle to be tested may be generated based on the performance test results in the virtual space dimensions.
[0063] Optionally, the virtual space parameters may be determined in advance based on the device structure of the target virtual reality device.
[0064] Optionally, before the step of mapping the performance test result to the target virtual reality device based on the virtual space parameters of the target virtual reality device to generate the performance test animation corresponding to the vehicle to be tested, the method further includes:
[0065] The performance test results are input into a platform / application with simulation function to obtain the simulated performance test results, so as to enable subsequent mapping and display based on the simulated performance test results.
[0066] Optionally, the above steps map the performance test results to the target virtual reality device based on the virtual space parameters of the target virtual reality device to generate a performance test animation corresponding to the vehicle to be tested, including the following steps:
[0067] Obtain preset viewing angle information of the target virtual reality device;
[0068] Determine virtual space parameters of a target virtual reality device according to preset viewing angle information;
[0069] Based on the virtual space parameters, the performance test results are mapped to the spatial coordinate system of the target virtual reality device to obtain the spatial coordinate data of the vehicle to be tested in the target virtual reality device;
[0070] Based on the spatial coordinate data, a performance test animation corresponding to the vehicle to be tested is generated.
[0071] Specifically, the preset perspective information refers to the pre-set visual information for observing the situation, and the preset perspective information may include the placement position and placement angle of the perspective, etc. The spatial coordinate data refers to the performance test results in the corresponding coordinate system of the target virtual reality device. The performance test animation refers to the animation that displays the performance test process and results of the vehicle to be tested, and the performance test animation may be three-dimensional.
[0072] The implementation method for obtaining the preset viewing angle information of the target virtual reality device may be to identify the current viewing angle of the target virtual reality device and obtain the preset viewing angle information of the target virtual reality device based on the identification result; or it may be to plan the viewing angle based on the structure of the target virtual reality device and determine the preset viewing angle information of the target virtual reality device based on the planned viewing angle.
[0073] The method for determining the virtual space parameters of the target virtual reality device according to the preset viewing angle information may be to determine the angle information and position information of the preset viewing angle according to the preset viewing angle information, and determine the virtual space parameters of the target virtual reality device based on the angle information and the position information.
[0074] Based on the virtual space parameters, the performance test results are mapped to the spatial coordinate system of the target virtual reality device. There are many ways to obtain the spatial coordinate data of the vehicle to be tested in the target virtual reality device. The specific implementation method is determined according to the actual situation, and this application does not limit it here.
[0075] In a possible implementation of the present application, based on the virtual space parameters, the performance test results are mapped to the spatial coordinate system of the target virtual reality device to obtain the spatial coordinate data of the vehicle to be tested in the target virtual reality device. The performance test results may be mapped to the spatial coordinate system of the target virtual reality device to obtain initial performance test results, and the initial performance test results are adjusted based on the virtual space parameters to obtain the spatial coordinate data of the vehicle to be tested in the target virtual reality device.
[0076] In another possible implementation of the present application, based on the virtual space parameters, the performance test results are mapped to the spatial coordinate system of the target virtual reality device to obtain the spatial coordinate data of the vehicle to be tested in the target virtual reality device. The initial virtual space can be determined in the target virtual reality device based on the virtual space parameters, the performance test results are mapped to the spatial coordinate system of the target virtual reality device, and the performance test results in the spatial coordinate system are filled into the initial virtual space to obtain the spatial coordinate data of the vehicle to be tested in the target virtual reality device.
[0077] The implementation method of generating the performance test animation corresponding to the vehicle to be tested based on the spatial coordinate data can be to generate animation data for the performance test of the vehicle to be tested based on the spatial coordinate data, fill the interactive information in the animation data, and obtain the performance test animation corresponding to the vehicle to be tested.
[0078] By applying the solution of the embodiment of the present application, based on the preset viewing angle information of the target virtual reality device, the virtual space parameters are determined, so that the performance test results are mapped to the spatial coordinate system of the target virtual reality device using the virtual space parameters, and the performance test animation corresponding to the vehicle to be tested is obtained, so that the profound performance test animation is generated based on the performance test results in the spatial coordinate system corresponding to the target virtual reality device, thereby realizing the intuitive display of the performance test results of the vehicle to be tested.
[0079] Optionally, before the above step of generating the performance test animation corresponding to the vehicle to be tested based on the spatial coordinate data, the following steps are also included:
[0080] Input the performance test results into the Unreal Engine, perform interactive design through the Unreal Engine, and obtain interactive parameters;
[0081] The above steps generate a performance test animation corresponding to the vehicle to be tested based on the spatial coordinate data, including the following steps:
[0082] Based on the spatial coordinate data and interaction parameters, a performance test animation corresponding to the vehicle to be tested is generated.
[0083] Specifically, Unreal Engine refers to an engine that generates interactive parameters in animations generated in target virtual reality devices. For example, Unreal Engine users generate interactive designs required for performance test animations in target virtual reality devices to obtain interactive parameters. Interactive design refers to adding interactive design actions and information to animations, such as displaying a control panel by clicking and displaying product information by touching. Interactive parameters refer to parameters required for interaction, such as interaction methods, interaction locations, interactive sound effects, etc., where interactive sound effects refer to sound effects that are emitted when interaction occurs.
[0084] Optionally, the Unreal Engine includes a physics collision module. Rigid object collision allows the user to fully utilize the program's object collision for real-world experience. All rendered objects and models can have dynamic properties set and simple collision sound effects made.
[0085] The performance test results are input into the Unreal Engine, and the Unreal Engine performs interaction design to obtain the interaction parameters. The implementation method may be that the performance test results are input into the Unreal Engine, and based on a preset interaction design method, the Unreal Engine performs interaction design based on the performance test results to obtain the interaction parameters. The preset interaction design method may be designed according to specific actual conditions. For example, the preset interaction design method may be to interact through interaction objects, and specifically, product information of the product may be obtained through the interaction objects. The Unreal Engine may perform interaction design based on the product information and the interaction objects to obtain the interaction parameters.
[0086] An implementation method for generating a performance test animation corresponding to the vehicle to be tested based on spatial coordinate data and interaction parameters may be to generate a first animation based on the spatial coordinate data, and based on the interaction parameters, add interaction content corresponding to the interaction parameters to the first animation to generate a performance test animation corresponding to the vehicle to be tested.
[0087] By applying the solution of the embodiment of the present application, the performance test results are input into the Unreal Engine, and the interaction design is performed through the Unreal Engine to obtain the interaction parameters, so that the implementation method of generating the performance test animation based on the spatial coordinate data is to generate the performance test animation corresponding to the vehicle to be tested based on the spatial coordinate data and the interaction parameters, so that interaction can be performed in the generated performance test animation, which adds a richer design for the intuitive display and improves the display quality of the performance test animation.
[0088] Optionally, the above steps of inputting the performance test results into the Unreal Engine, performing interaction design through the Unreal Engine, and obtaining interaction parameters include the following steps:
[0089] Obtaining pre-designed interactive objects and preset interactive information corresponding to performance tests;
[0090] Determine vehicle information after the performance test of the vehicle to be tested according to the performance test result;
[0091] The interactive object, preset interactive information and vehicle information are input into the Unreal Engine to obtain the interactive parameters.
[0092] Specifically, the interactive object refers to the object for interaction in the target virtual reality device, for example, the interactive object can be a small ball, a small cube, etc. Preset interactive information refers to the information that is preset to be processed accordingly when an interactive action occurs, for example, the preset interactive information can be the code that pops up the UI during the interaction. Vehicle information refers to the attribute information of the vehicle, for example, the vehicle information includes a series of information such as the appearance of the vehicle, the value of the vehicle, the power configuration of the vehicle, and the performance of the vehicle.
[0093] Optionally, the acquired interactive object may include an installation position and an installation angle of the angle object.
[0094] The implementation method of obtaining the preset interaction information corresponding to the performance test may be to obtain the preset interaction information corresponding to the performance test based on the performance test scenario parameters and the performance test results.
[0095] The method for determining the vehicle information after the performance test of the vehicle to be tested according to the performance test results may be to extract information from the performance test results to obtain the vehicle information after the performance test of the vehicle to be tested, wherein the extracted information dimension may vary according to different performance test scenario parameters. For example, if the performance test scenario is 100-meter acceleration, the extracted vehicle information at least includes the vehicle's 100-meter acceleration parameters; if the performance test scenario is vehicle collision, the extracted vehicle information at least includes the vehicle's collision parameters.
[0096] The interactive object, preset interactive information and vehicle information are input into the Unreal Engine to obtain the interactive parameters. The vehicle information can be written into the user interface in the form of preset interactive information, and the user interface is associated with the interactive object to obtain the interactive parameters.
[0097] By applying the solution of the embodiment of the present application, a pre-designed interactive object and preset interactive information corresponding to the performance test are obtained, and based on the performance test results, the vehicle information after the performance test of the vehicle to be tested is determined, and the interactive object, preset interactive information and vehicle information are input into the Unreal Engine to obtain interactive parameters, so that a performance test animation containing interactive functions can be generated subsequently through the interactive parameters including the interactive object, preset interactive information and vehicle information, thereby improving the richness of the performance test animation display of the vehicle to be tested.
[0098] Optionally, the above steps generate a performance test animation corresponding to the vehicle to be tested based on the spatial coordinate data and the interaction parameters, including the following steps:
[0099] Generate an initial performance test animation corresponding to the vehicle to be tested based on the spatial coordinate data and the interactive objects;
[0100] When it is identified in the initial performance test animation that the interactive object meets the preset interactive information, an interactive interface including the vehicle information is displayed in the initial performance test animation, and a performance test animation corresponding to the vehicle to be tested is generated.
[0101] Specifically, the initial performance test animation refers to an animation that initially displays the performance test results of the vehicle to be tested, and an interactive function is added to the initial performance test animation. The interactive interface refers to an interface with interactive functions. For example, when the interactive object is touched, the interactive object will pop up a UI interface, and then it is determined that the interactive object includes an interactive interface.
[0102] The implementation method of generating the initial performance test animation corresponding to the vehicle under test based on the spatial coordinate data and the interactive object can be to generate animation data corresponding to the vehicle under test based on the spatial coordinate data, add the interactive object to the animation data, and generate the initial performance test animation corresponding to the vehicle under test.
[0103] When it is recognized in the initial performance test animation that the interactive object meets the preset interactive information, an interactive interface containing the vehicle information is displayed in the initial performance test animation, and a performance test animation corresponding to the vehicle to be tested is generated. The implementation method may be that when it is recognized in the initial performance test animation that the interactive object meets the conditions corresponding to the preset interactive information, an interactive interface containing the vehicle information is displayed in the initial performance test animation, and a performance test animation corresponding to the vehicle to be tested is generated.
[0104] By applying the solution of the embodiment of the present application, an initial performance test animation corresponding to the vehicle to be tested is generated based on the spatial coordinate data and the interactive object, and when it is identified in the initial test animation that the interactive object meets the preset interactive information, an interactive interface containing the vehicle information is displayed to generate a performance test animation. In the generated performance test animation, the interactive interface containing the vehicle information can be displayed through the interactive object, so that the vehicle information of the vehicle to be tested can be viewed intuitively, thereby improving the user experience.
[0105] Optionally, the above steps generate an initial performance test animation corresponding to the vehicle to be tested based on the spatial coordinate data and the interactive object, including the following steps:
[0106] Based on the spatial coordinate data, determine the animation data corresponding to the vehicle to be tested;
[0107] Placing the interactive object at a preset position in the animation data to obtain updated animation data;
[0108] Based on the animation data, an initial performance test animation corresponding to the vehicle to be tested is generated.
[0109] Specifically, the animation data refers to the data of the animation dimension corresponding to the spatial coordinate data. The preset position refers to the preset position for placing the interactive object.
[0110] The method for determining the animation data corresponding to the vehicle to be tested based on the spatial coordinate data may be to generate the animation data corresponding to the vehicle to be tested according to a preset animation generation method, wherein the preset animation generation method may be a preset spatial data animation sequence, so that the spatial coordinate data generates the animation data corresponding to the vehicle to be tested according to the preset spatial data animation sequence.
[0111] The interactive object may be placed at a preset position in the animation data to obtain updated animation data by identifying an object identifier of the interactive object and a position identifier of the preset position, matching the object identifier and the position identifier, and based on the matching result, placing the interactive object at the preset position in the corresponding animation data to obtain updated animation data.
[0112] The method for generating the initial performance test animation corresponding to the vehicle to be tested according to the animation data may be to convert the animation data into animation dimensions to obtain the initial performance test animation corresponding to the vehicle to be tested.
[0113] By applying the scheme of the embodiment of the present application, animation data of the vehicle to be tested is determined based on spatial coordinate data, and the interactive object is placed at a preset position in the animation data to obtain updated animation data. An initial performance test animation of the vehicle to be tested is generated based on the animation data, so that the generated initial performance test animation includes the spatial coordinate data corresponding to the interactive object and the vehicle to be tested, which facilitates the subsequent judgment based on the initial performance test animation whether the interactive object identified in the initial performance test animation meets the preset interactive information, so as to generate a performance test animation corresponding to the vehicle to be tested.

[0119] In an embodiment of the present application, a performance test is performed on the vehicle to be tested based on the vehicle parameters and test scenario parameters of the vehicle to be tested, and a performance test result of the vehicle to be tested is obtained. The performance test result is mapped to a target virtual reality device to convert the performance test result to a virtual reality dimension, and a performance test result corresponding to the vehicle to be tested is generated, thereby improving the intuitiveness of the performance test result, thereby enabling a user to intuitively view the performance test result of the vehicle to be tested through the target virtual reality device.
[0120] The following combination Figure 2a Taking the application of the vehicle performance test method provided by the present application in the vehicle collision performance test as an example, the vehicle performance test method is further described. Figure 2a A process flow chart of a vehicle performance testing method provided by an embodiment of the present application is shown, which specifically includes the following steps:
[0121] Step 202: Obtain vehicle parameters and test scenario parameters of the vehicle to be tested.
[0122] The vehicle structure, vehicle configuration and vehicle collision scenario test parameters of the vehicle to be tested X are obtained, wherein the vehicle collision scenario test parameters include information such as obstacle position and obstacle structure.
[0123] Step 204: Input the vehicle parameters and the test scenario parameters into the vehicle performance test model to obtain the output result of the vehicle performance test model.
[0124] The vehicle structure, vehicle configuration and vehicle collision scenario test parameters are input into the vehicle performance test model, and a performance test is performed on the vehicle to be tested to obtain the output results of the vehicle performance test model, wherein the output results may include the vehicle model of the vehicle to be tested, the scenario model of the vehicle collision test scenario, and the process and results of the performance test.
[0125] Step 206: Restore the output result to the program compilation intermediate code file to obtain the performance test result of the vehicle to be tested.
[0126] The output result file of the vehicle performance test model is restored to the program compilation intermediate code file (.obj) to obtain the performance test result of the vehicle to be tested.
[0127] Step 208: Obtain preset viewing angle information of the target virtual reality device.
[0128] The preset viewing angle information in the VR device is obtained, wherein the preset viewing angle information includes the viewing angle information of the virtual camera.
[0129] Step 210: Determine virtual space parameters of the target virtual reality device according to the preset viewing angle information.
[0130] According to the preset viewing angle information, the position information, viewing angle information, etc. of the virtual camera in the VR device are determined.
[0131] Step 212: Based on the virtual space parameters, the performance test results are mapped to the spatial coordinate system of the target virtual reality device to obtain the spatial coordinate data of the vehicle to be tested in the target virtual reality device.
[0132] Based on the position information and viewing angle information of the virtual camera, the performance test results are mapped to the spatial coordinate system corresponding to the VR device to obtain the spatial coordinate data of the vehicle X to be tested in the VR device.
[0133] Step 214: Input the performance test results into the Unreal Engine, perform interaction design through the Unreal Engine, and obtain interaction parameters.
[0134] Obtain the pre-designed blue ball and the code for the UI that pops up when the performance test corresponds to the interaction. According to the performance test results, obtain the vehicle product information and vehicle performance information of the vehicle X to be tested. Import the vehicle product information and vehicle performance information into the Unreal Engine. When displaying the UI, obtain the corresponding information from the Unreal Engine for display. Add the interaction design code to the blue ball so that when the blue ball interacts with the handle, a UI interface pops up, and the vehicle product information and vehicle performance information are displayed in the UI interface. Generate interaction parameters based on the above interaction logic.

Edit the UI code, which is used to pop up the UI when the collision box interacts; Step 4. Import the vehicle information into the Unreal Engine; Step 5. Create a UI interface, which is used to display the vehicle information; Step 6. When the UI pops up, read the information to be displayed in the vehicle information and display it in the UI interface; Step 7. Place the activity in the corresponding position.
[0137] Through the above steps 1 to step 7, the performance test animation has an interactive function. When the performance test animation is running, the player can interact with the blue ball through the handle, and the blue ball will pop up a UI interface, which will display vehicle information about the vehicle to be tested.
[0138] Step 216: Generate a performance test animation corresponding to the vehicle to be tested based on the spatial coordinate data and the interaction parameters.
[0139] Generate animation data based on spatial coordinate data, add interactive objects to the preset positions of the animation data, generate the initial vehicle collision performance test animation, and display the interactive interface in the initial vehicle collision performance test animation when the blue ball meets the interactive conditions and the UI pops up, and generate the performance test animation corresponding to the vehicle to be tested.

[0141] Step 1, start execution; Step 2, program compiles intermediate code file, the file format of vehicle parameters and test scenario parameters is program compiles intermediate code file; Step 3, restores to program compiles intermediate code file, the file format of the output result of the vehicle performance test model is non-program compiles intermediate code file, then restores the output result to program compiles intermediate code file, and obtains the performance test result of the vehicle to be tested; Step 4, outputs to Unreal Engine, inputs the performance test result into Unreal Engine; Step 5, designs UI interaction interface; Step 6, Unreal Engine; Step 7, test, click on the blue ball to trigger the collision box to display the UI interface, and the information displayed on the UI interface is obtained from Unreal Engine; Step 8, end execution.
