Description

Technical Field

[0001] This application relates to the field of computer technology, and in particular to a testing system. Background Technology

[0002] With the development of smart cockpit technology, in-vehicle systems are becoming increasingly capable of performing a wide range of functions. For example, navigation, music playback, and phone calls can be achieved through the in-vehicle screen. To improve the driving experience for testers, they can regularly test the smoothness of the in-vehicle system and optimize its operation based on the test results.

[0003] In some solutions, the smoothness of the in-vehicle system is assessed by having testers observe the response speed of the in-vehicle screen. However, the test results are subjective and cannot be quantified or accurate. In other solutions, high-cost hardware and software equipment needs to be customized for different vehicle models and operating systems to test the smoothness of the in-vehicle system. However, the configuration process is complex and the material and labor costs are relatively high.

[0004] Therefore, it is currently necessary to improve the accuracy of testing the smoothness of vehicle-mounted systems while controlling testing costs. Utility Model Content

[0005] To improve the accuracy of testing the smoothness of vehicle-mounted systems while controlling testing costs, this application provides a testing system.

The touch detection device is used to send touch information of a tester to the testing device. The touch information of the tester includes a release signal, which is used to instruct the tester to end touching the in-vehicle screen at a first moment. The image acquisition device is used to capture first video data of the tester touching the in-vehicle screen and send the first video data to the testing device. The testing device is used to detect the operation on the first video data and play the first image data at a first moment and the image data after the first moment in the first video data. The testing device is used to determine a first time interval based on the first image data corresponding to the first moment in the first video data and the second image data corresponding to the second moment, wherein the second image data is the image data that is different from the first image data in the frame with the closest interval to the first image data.

[0007] It is understood that the testing equipment may refer to the computer 30 mentioned in the embodiments of this application, the touch detection equipment may refer to the infrared touch screen 11 mentioned in the embodiments of this application, and the image acquisition equipment may refer to the high frame rate industrial camera 20 mentioned in the embodiments of this application, etc., and is not limited here.

[0009] Based on the above solution, testers can use testing equipment to accurately measure the response speed of the in-vehicle screen and thereby evaluate the smoothness of the in-vehicle device's operation, i.e., the smoothness of the in-vehicle system's operation. Furthermore, the testing equipment, touch detection equipment, and image acquisition equipment used in this embodiment have low testing costs, enabling accurate testing of the in-vehicle device's operational smoothness while controlling testing costs.

[0010] In one possible implementation of the first aspect described above, the image acquisition device is a camera; the camera's sampling frame rate is a first sampling frame rate, which is twice the screen refresh rate of the vehicle screen.

[0012] It is understood that in some other embodiments of this application, the first sampling frame rate may also be other data that matches the screen refresh rate of the vehicle screen. For example, the first sampling frame rate may also be set to four times the screen refresh rate of the vehicle screen, etc., which is not limited here.

[0013] In one possible implementation of the first aspect described above, the camera includes an industrial camera.

[0014] In one possible implementation of the first aspect described above, the touch detection device includes an infrared touchscreen.

[0019] In this embodiment of the application, the first application can play back the first video data and preview the first video data frame by frame, so that the tester can determine the first frame image data rendered after the vehicle screen responds to the tester's end of touching the vehicle screen, that is, the second image data at the second moment.

[0020] In one possible implementation of the first aspect described above, the test device includes a first application; the first application is used to receive touch information from a tester, the touch information including a release signal, the release signal being used to instruct the tester to end touching the vehicle screen at a first moment; the first application is used to receive first video data from the tester touching the vehicle screen of the vehicle device; the first application is used to detect a first operation on the first video data and play first image data corresponding to the first moment in the first video data; the first application is used to detect a second operation on the first video data and display second image data corresponding to the second moment in the first video data, wherein the second image data is different from the first image data; the first application is used to calculate a first time interval based on the first moment and the second moment and display the first time interval; the first application is used to determine the smoothness of operation of the vehicle device based on the first time interval.

[0021] In one possible implementation of the first aspect described above, the tester touch information also includes a start signal, which instructs the tester to begin touching the vehicle screen at a third moment.

[0022] In this embodiment of the application, the third moment can represent the moment when the tester last touched the vehicle screen. The third moment is earlier than the second moment mentioned above. The second moment can represent the moment when the tester last ended touching the vehicle screen. That is, the third moment and the second moment can correspond to the moment when the tester last touched the vehicle screen and the moment when the tester last ended touching the vehicle screen, respectively.

[0034] The illustrative embodiments of this application include, but are not limited to, a testing system.

[0035] It is understood that the electronic devices in the embodiments of this application may also be referred to as terminals, user equipment (UE), mobile stations (MS), mobile terminals (MT), etc. Terminal devices may include mobile phones, smart TVs, wearable devices, tablets, computers with wireless transceiver capabilities, cameras with wireless charging, vehicle dashcams, video doorbells with wireless charging, virtual reality (VR) terminal devices, augmented reality (AR) terminal devices, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, etc.

[0036] As mentioned earlier, when testing the smoothness of in-vehicle systems, some solutions assess the smoothness of the system by having testers observe the response speed of the in-vehicle screen. However, the test results are subjective and cannot be quantified or accurate. In other solutions, it is necessary to customize high-cost hardware and software equipment for different vehicle models and operating systems to test the smoothness of the in-vehicle system. However, the configuration process is complex and the material and labor costs are relatively high.

[0037] To address the aforementioned issues, this application provides a testing system and testing equipment. The testing system includes an in-vehicle device, a testing device, a touch detection device, and an image acquisition device. The in-vehicle device includes an in-vehicle screen. The touch detection device covers the surface of the in-vehicle screen and is connected to the testing equipment. The touch detection device sends touch information from a tester to the testing equipment, including a release signal that instructs the tester to end touching the in-vehicle screen at a first moment. The image acquisition device captures first video data of the tester touching the in-vehicle screen and sends the first video data to the testing equipment. The testing equipment detects the operation on the first video data and plays first image data at a first moment and image data after the first moment in the first video data. The testing equipment determines a first time interval based on the first image data corresponding to the first moment in the first video data and the second image data corresponding to the second moment, wherein the second image data is the frame closest to the first image data that is different from the first image data.

[0038] It is understandable that the first time interval between the first moment and the second moment can accurately characterize the response speed of the in-vehicle screen, that is, the smoothness of the operation of the in-vehicle device.

[0039] Based on the above testing system, testers can easily and quickly obtain accurate response speed of the in-vehicle screen and use this to evaluate the smoothness of the in-vehicle equipment's operation. This means that the accuracy of the smoothness of the in-vehicle system's operation can be improved while controlling testing costs.

[0040] It is understood that testing equipment can refer to electronic devices such as computers, touch detection equipment can include infrared touchscreens, and image acquisition equipment can include cameras. Cameras can be industrial cameras, such as high frame rate industrial cameras, and are not limited here.

[0041] The following example uses a computer as the testing device, an infrared touch screen as the touch detection device, and a high frame rate industrial camera as the image acquisition device. The specific implementation process of the technical solution provided in the embodiments of this application will be described in detail with reference to the accompanying drawings.

[0042] For example, Figure 1 According to an embodiment of this application, a schematic diagram of a testing system is shown.

[0043] refer to Figure 1 The testing system includes in-vehicle equipment in a car (00), an infrared touchscreen, a high frame rate industrial camera (20), and a computer (30). The in-vehicle equipment includes an in-vehicle screen (10). The infrared touchscreen can cover the surface of the in-vehicle screen (10), and touching the in-vehicle screen (10) is equivalent to touching the infrared touchscreen. The in-vehicle screen (10) can respond to touch operations by the tester, activating corresponding functions and displaying corresponding interfaces. The high frame rate industrial camera (20) can be used to acquire image data from the in-vehicle screen (10) and send the acquired first video data, including multiple image data, to a first application on the computer (30).

[0044] It is understood that the testing equipment includes a first application; the first application is used to receive touch information from a tester, the touch information including a release signal, the release signal being used to instruct the tester to end touching the vehicle screen at a first moment; the first application is used to receive first video data from the tester touching the vehicle screen of the vehicle device; the first application is used to detect a first operation on the first video data and play first image data corresponding to the first moment in the first video data; the first application is used to detect a second operation on the first video data and display second image data corresponding to the second moment in the first video data, wherein the second image data is different from the first image data; the first application is used to calculate a first time interval based on the first moment and the second moment and display the first time interval; the first application is used to determine the smoothness of operation of the vehicle device based on the first time interval.

[0045] It is understandable that in some solutions, to improve testing speed and efficiency, the first application compresses and stores the first video data in memory. However, in this embodiment, to meet the data persistence needs of testers in certain situations, the first application provided in this embodiment can transcode the first video data and save it as a video file on disk, as well as save single frames. Furthermore, to facilitate testers' management of test data, the first application can provide video data export functions in various formats, including but not limited to: exporting to Excel / CSV files, exporting to XML / JSON files, and uploading to custom adaptation platforms via an application programming interface (API).

[0046] It is understandable that the high frame rate industrial camera 20 can have high resolution and high sampling frame rate to ensure that it can accurately capture the screen status of the vehicle screen 10 under various lighting conditions.

[0047] In this embodiment, the sampling frame rate of the high frame rate industrial camera 20 can be preset to match the screen refresh rate of the vehicle screen 10. For example, to obtain more accurate test data, the sampling frame rate of the high frame rate industrial camera 20 can be preset to twice the screen refresh rate of the vehicle screen 10.

[0048] For example, assuming the screen refresh rate of the vehicle-mounted screen 10 is 60Hz, this means the screen refreshes 60 times per second. Based on this, the sampling frame rate of the high frame rate industrial camera 20 can be set to 120fps, with a maximum error of no more than 8ms. Thus, the high frame rate industrial camera 20 can capture 120 frames of image data per second. This ensures that the high frame rate industrial camera 20 can capture the image data corresponding to each screen refresh of the vehicle-mounted screen 10, improving sampling accuracy.

[0049] It is understandable that during the process of the high frame rate industrial camera 20 capturing images from the vehicle screen 10, the first application supports real-time preview of the first video data corresponding to the captured images from the vehicle screen 10, so that testers can adjust and confirm the validity of the test in a timely manner. Furthermore, after the high frame rate industrial camera 20 has completed capturing images from the vehicle screen 10 and obtained the corresponding first video data, the first application supports playback and frame-by-frame preview of the first video data. Simultaneously, each frame displays a timestamp accurate to the millisecond level, facilitating testers to confirm the time corresponding to each frame of image data.

[0050] It is understood that, in this embodiment of the application, the tester can pre-configure the camera of the high frame rate industrial camera 20 and set the camera parameters based on the first application. The camera parameters may include resolution, acquisition frame rate, exposure time, etc., so that the tester can flexibly configure them according to different test requirements and test environments.

[0051] In some embodiments of this application, to determine the moment when a tester touches the vehicle screen, the touch operation of the tester on the vehicle screen can be detected based on a touch detection device. The touch detection device can be an infrared touchscreen, which can be used to detect the touch operation of the tester on the vehicle screen, and the infrared touchscreen can send the tester's touch information to the test equipment (such as a computer).

[0052] For example, Figure 2 A schematic diagram of another testing system is shown. Figure 2 In this embodiment, the surface of the vehicle screen 10 includes an infrared touchscreen 11, which can be connected to the computer 30 via a universal serial bus (USB). It is understood that the infrared touchscreen 11 can cover the surface of the vehicle screen 10, and the size of the infrared touchscreen 11 can match the size of the vehicle screen 10; this is not limited here.

[0053] In some embodiments of this application, the touch detection device (such as an infrared touch screen) on the surface of the vehicle screen of the vehicle-mounted device can send touch information of the tester to the test device (such as a computer). The touch information of the tester includes a start signal, which is used to instruct the tester to start touching the vehicle screen of the vehicle-mounted device at a third moment.

[0054] For example, when a tester touches the vehicle screen 10, the infrared touchscreen 11 can detect the touch and send a start signal to the computer 30. The start signal is used to instruct the tester to touch the vehicle screen 10. The moment when the tester touches the vehicle screen 10 can be named the third moment.

[0055] In some embodiments of this application, the touch detection device (such as an infrared touch screen) can send touch information of the tester to the test device (such as a computer). The touch information of the tester may include a release signal, which instructs the tester to end touching the vehicle screen of the vehicle device at a first moment.

[0056] For example, when the tester stops touching the vehicle screen 10, the infrared touchscreen 11 can detect this and send a release signal to the computer 30. The release signal is used to instruct the tester to stop touching the vehicle screen 10. The moment when the tester stops touching the vehicle screen 10 is also known as the first moment.

[0057] Based on this, the computer 30 can receive the start signal and the release signal, and record the moment when the release signal is received. The moment when the release signal is received is also the moment when the tester ends touching the vehicle screen 10.

[0058] It is understood that the infrared touchscreen 11 provided in this embodiment can cover the surface of the vehicle screen 10. For example, the infrared touchscreen 11 can be attached to the entire surface of the vehicle screen 10. Furthermore, the infrared touchscreen 11 can be customized in size according to the shape and size of the vehicle screen 10. In addition, the infrared touchscreen 11 provided in this embodiment supports single-point and multi-point touch, can be connected to the computer 30 via USB, and sends release signals to the first application on the computer 30. Thus, the hardware and software costs required for testing based on the testing system provided in this embodiment are relatively low.

[0059] For ease of understanding, Figure 3 This diagram illustrates the principle of touch detection in an infrared touchscreen. The following is based on... Figure 3 The detection principle of infrared touch screens will be explained in detail.

[0060] like Figure 3 As shown, the infrared touchscreen 11 includes multiple emitting diodes and receiving diodes. The emitting diodes emit infrared rays, and the receiving diodes receive the infrared rays emitted by the emitting diodes. The multiple emitting diodes are distributed in the X and Y directions of the infrared touchscreen 11, with the X direction being horizontal and the Y direction being vertical; the multiple receiving diodes are also distributed in the X and Y directions of the infrared touchscreen 11. The infrared touchscreen 11, through the multiple emitting diodes and receiving diodes distributed in the X and Y directions, forms a dense infrared matrix in the X and Y directions in front of the vehicle screen 10, and continuously scans for any infrared rays blocked by objects, thereby detecting and locating the touch operation and touch position of the tester.

[0061] For example, if a tester touches the vehicle screen 10, the touch operation will block the infrared light emitted by a certain transmitter, preventing the corresponding receiver from receiving the infrared light. Based on this, the infrared touch screen 11 can determine the corresponding position coordinates A, that is, the touch position corresponds to touch point A.

[0062] This application provides a testing device for receiving touch information from a tester, including a release signal instructing the tester to end touching the vehicle screen at a first moment; the testing device for receiving first video data from the tester touching the vehicle screen; the testing device for detecting a first operation on the first video data and playing first image data corresponding to the first moment in the first video data; the testing device for detecting a second operation on the first video data and displaying second image data corresponding to the second moment in the first video data, wherein the second image data is different from the first image data; the testing device for calculating a first time interval based on the first moment and the second moment and displaying the first time interval; and the testing device for determining the smoothness of operation of the vehicle device based on the first time interval.

[0063] For example, Figure 4 According to an embodiment of this application, a schematic diagram of a process for testing the operational smoothness of in-vehicle equipment using testing equipment is shown. It can be understood that... Figure 4 The executing entities for each process shown can be the aforementioned Figure 2 The testing equipment shown (such as computer 30, etc.) is not limited here.

[0064] S401: Receives touch information from the tester, which includes a release signal that instructs the tester to stop touching the vehicle screen at the first moment.

[0065] In some embodiments of this application, a first application in the test device can receive touch information from a tester, which can be sent to the test device by a touch detection device. The touch information may include a release signal, which instructs the tester to end touching the vehicle screen at a first moment.

[0066] It is understandable that the tester can launch the first application based on the test equipment and receive the tester's touch information. The touch detection device can be an infrared touch screen 11, and the test equipment can be a computer 30.

[0067] For example, Figure 5A A schematic diagram 501 of the interface of a computer 30 is shown. (Reference) Figure 5A In the interface 501 of the computer 30, corresponding to the click operation of the tester on the first application 502 in the computer 30, the computer 30 displays the interface diagram of the first application 502, and the first application 502 can play the first video data captured by the high frame rate industrial camera 20.

[0068] It is understood that the first application can run on a personal computer (PC) or other high-performance computing device, such as computer 30. The first application can be used to monitor, manage, and control lower-level devices, such as in-vehicle equipment. Furthermore, the first application can perform functions including data acquisition, data processing, visualization, control and monitoring, logging, and remote access.

[0069] It is understood that the first application in this embodiment can be a first application developed based on Python and QT 6. Python is a high-level programming language widely used for various application development. QT 6 is a powerful cross-platform application development framework suitable for developing desktop, mobile, and embedded system applications. Furthermore, the first application in this embodiment can run on operating systems such as Windows, and this is not limited thereto.

[0070] S402: The first operation is detected, the first image data of the first video data is played, and the first moment corresponding to the first image data is displayed.

[0071] In some embodiments of this application, a first operation is detected. The first operation may be a trigger operation by a tester on the playback control of the first video data, and the first image data and the corresponding first moment of the first video data are played, as well as the image data after the first moment are played.

[0072] In other embodiments, the first operation may also be a click operation by a tester on the first application.

[0073] For example, computer 30 detects the first operation, which can be one of the above. Figure 5A The tester clicked on the first application 502. Corresponding to the first operation, the computer 30 can display as follows: Figure 5B The interface diagram shown is 503.

[0074] refer to Figure 5B ,exist Figure 5B The interface 503 of the first application, as shown, includes a video data playback area, video recording, performance calculation, and video storage. Based on the tester's first operation, the interface 503 of the first application starts playing the first video data from the first image data A in the first video data.

[0075] It can be understood that the first image data A is the first frame of image data in the first video data. The first time corresponding to the first image data A is "2024 / 10 / 24 14:11:23.908". Based on this, in the performance calculation, the finger touch time can be automatically displayed as the first time "2024 / 10 / 24 14:11:23.908", where the finger touch time refers to the moment when the tester ends touching the vehicle screen.

[0076] It is understandable that the first moment can be the moment when the tester's finger stops touching the in-vehicle screen during the last touch during the test.

[0077] S403: The second operation is detected. Play the second image data of the first video data and display the second moment corresponding to the second image data.

[0078] In some embodiments of this application, during the playback of the first video data, the test device detects a second operation on the first video data, plays the second image data corresponding to the second moment in the first video data, and displays the second moment corresponding to the second image data and the first time interval.

[0079] In some embodiments of this application, the second operation is a tester's triggering operation on the control of the next frame.

[0080] For example, the testing device, i.e., computer 30, can detect the second operation, which can be as described above. Figure 5B The image shows a tester clicking the next frame control 500. The next frame control 500 is a frame-by-frame fast-forward control. Furthermore, in response to the second operation, the computer 30 can display... Figure 5C Another interface diagram 503 is shown.

[0081] refer to Figure 5C ,exist Figure 5C In the interface 504 of the first application shown, based on the tester's click operation on the next frame control 500, the second image data B in the first video data is displayed. It can be understood that the second image data B is the image data that begins to be rendered after the tester finishes touching the vehicle screen. Based on this, in the performance calculation, the rendering completion time 5040 corresponding to the second image data B can be displayed, i.e., the second time "2024 / 10 / 24 14:11:26.809".

[0082] In some embodiments of this application, the vehicle-mounted screen can render and display multiple frames of repeating image data in response to the tester ending their touch on the screen. To determine whether the second image data B in the first video data is the first frame of image data rendered when the vehicle-mounted screen responds to the tester ending their touch, the tester can click... Figure 5C The next frame control 500 is used to compare the second image data B with the next frame image data.

[0083] For example Figure 5D In the interface 505 of the first application 502 shown, the third image data B is displayed. The performance calculation displays the rendering completion time 5050 corresponding to the third image data B, i.e., "2024 / 10 / 24 14:11:28.800". It can be seen that the third image data B is the same as the second image data B, and the third image data B is displayed after the second image data B. Based on this, it can be determined that the second image data B is the first frame of image data rendered after the vehicle screen response tester ends touching the vehicle screen.

[0084] S404: Displays the first time interval between the first and second time points.

[0085] In some embodiments of this application, based on a first time point determined by the first application 502 and a second time point determined by the tester, the first application 502 can automatically calculate the time interval between the first time point and the second time point, referring to the above. Figure 5C In the interface 504 of the first application shown, the time consumption information 5041 displayed is "2901ms". This time consumption information 5041 is the first time interval, which can be used to characterize the accurate response speed of the in-vehicle screen, and thus characterize the smoothness of the in-vehicle system.

[0086] S405: Determine the response speed of the on-board equipment based on the first time interval.

[0087] In some embodiments of this application, testers can obtain a first time interval "2901ms" through the first application 502 and use the first time interval as the response speed of the vehicle device. Furthermore, testers can optimize the response speed of the vehicle device based on the first time interval; for example, the response speed of the vehicle device can be optimized to a value less than the first time interval "2901ms," which is not limited here.

[0088] Based on the first application in the test equipment of the aforementioned test system, the smoothness of the in-vehicle device's operation is tested. The configuration process required for the test is relatively simple, and the corresponding functional interface of the first application is simple yet complete, reducing the learning cost for testers. Furthermore, it can effectively improve the testing efficiency of testers during long-term testing.

[0089] Furthermore, the testing system provided in this application embodiment is applicable to the smoothness testing of most intelligent vehicle systems. Moreover, compared to precise performance testing solutions on the market, testing based on the testing system provided in this application embodiment can obtain accurate test results of the smoothness of vehicle equipment operation, while significantly reducing software, hardware, and labor costs.
