[0024] In order to make the technical problems, technical solutions and advantages to be solved by the present invention more clear, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0025] Figure 1 This is a flow chart of a cockpit display device detection method according to an embodiment of the present application. Figure 1 As shown, the cockpit display device detection method applied to the video board includes the following steps:

[0026] Step 101: Generate a control video data stream according to received test data.

[0027] Step 102: Compare the test video data stream output by the target cockpit display device with the control video data stream to determine a comparison result.

[0028] Step 103: Send the comparison result to the host computer, so that the host computer determines the detection result of the target cockpit display device according to the comparison result.

[0029] In order to understand whether the target cockpit display device can display normally, the video board will generate a control video data stream based on the received test data to compare with the test video data stream output by the target cockpit display device. Since the comparison method of the video board is a simple logical comparison, the video board sends the comparison result to the host computer, and a certain judgment logic can be stored in the host computer to determine whether the detection result of the target cockpit display device is passed or failed based on the comparison result.

[0030] It should be noted that the data used for the test video data stream output by the target cockpit display device is the same as the data used for the control video data stream generated by the video board.

[0031] In the embodiment of the present application, the video board and the target cockpit display device generate video data streams respectively, so that the video board can achieve automatic comparison, and then the detection result of the target cockpit display device is judged by the host computer according to the comparison result, with high accuracy and detection efficiency.

[0032] In one possible implementation, the control video data stream includes an R / G / B monochrome picture, and correspondingly, the test video data stream output by the target cockpit display device is compared with the control video data stream. The process of determining the comparison result may also include: parsing the test video data stream to obtain the R / G / B monochrome picture included in the test video data stream, and comparing the R / G / B monochrome picture included in the test video data stream with the R / G / B monochrome picture included in the control video data stream according to the monochrome pictures of the same color, and obtaining the comparison result according to the monochrome picture comparison results corresponding to each monochrome picture.

[0033] The control video data stream generated by the video board may include three monochrome pictures of R / G / B. In this scenario, the video board will parse the test video data stream output by the target cockpit display device, and divide the test video data stream into three monochrome pictures of R / G / B. At this time, the video board will compare the video stream data of the three color channels respectively. For example, the picture of the R color channel included in the control video data stream is compared with the picture of the R color channel included in the test video data stream, and the picture of the G color channel included in the control video data stream is compared with the picture of the G color channel included in the test video data stream, and so on, until the comparison of the video data streams of the three color channels is completed, and a comparison result is generated based on the comparison results of the three monochrome pictures generated by the three comparisons.

[0034] In the embodiment of the present application, by comparing the three monochrome images of R / G / B included in the test video data stream and the control video data stream respectively, the accuracy of the cockpit display device detection can be further improved.

[0035] In a possible implementation, the reference video data stream includes a plurality of pictures played in a loop at a fixed time interval. Correspondingly, the test video data stream output by the target cockpit display device is compared with the reference video data stream. The process of determining the comparison result may also include:

[0036] The test video data stream is parsed to obtain a plurality of pictures included in the test video data stream, and then the plurality of pictures included in the reference video data stream are compared with the plurality of pictures included in the test video data stream according to the cycle time of the reference video data stream to obtain a comparison result.

[0037] The control video data stream may include multiple pictures played in a loop at a fixed time interval, for example, 10 pictures, which are played in a loop in the same order at a time interval of 0.1 seconds. Since the control video data stream and the test video data stream are the same source, the test video data stream is parsed. Under ideal circumstances, 10 pictures in the same order can also be obtained. At this time, the pictures are compared one by one according to fixed time nodes to determine the comparison result.

[0038] In the embodiment of the present application, a higher accuracy is achieved by comparing pictures at fixed time nodes.

[0039] Figure 2 This is a flow chart of a cockpit display device detection method according to another embodiment of the present application. Figure 2 As shown, the test data includes the video test instructions sent by the host computer, and the corresponding cockpit display device detection method includes the following steps:

[0040] Step 201: Generate test video data according to a video test instruction, and generate a control video data stream according to the test video data.

[0041] Step 202: Perform a display test on the target cockpit display device according to the test video data, so that the target cockpit display device outputs a test video data stream.

[0042] Step 203: Compare the test video data stream output by the target cockpit display device with the control video data stream to determine a comparison result.

[0043] Step 204: Send the comparison result to the host computer, so that the host computer determines the detection result of the target cockpit display device according to the comparison result.

[0044] The test data received by the video board can be a video test instruction sent by the host computer. In this scenario, the host computer does not need to communicate with the target cockpit display device. The video board directly generates test video data according to the video test instruction, generates a control video data stream according to the test video data, and performs a display test on the target cockpit display device according to the test video data. The target cockpit display device will output the test video data stream to the video board. The video board compares the test video data stream output by the target cockpit display device with the control video data stream and can determine the comparison result. Since the comparison method of the video board is a simple logical comparison, the video board sends the comparison result to the host computer. Certain judgment logic can be stored in the host computer to determine whether the detection result of the target cockpit display device is passed or failed according to the comparison result.

[0045] In the embodiment of the present application, by directly sending video test instructions to the video board by the host computer, the data processing pressure of the target cockpit display device can be reduced, thereby improving the detection efficiency.

[0046] In a possible implementation manner, the process of performing a display test on the target cockpit display device according to the test video data may also include:

[0047] The test video data is serialized by a first serializer, wherein the first serializer matches a first deserializer in a target cockpit display device. The serialized test video data is sent to the target cockpit display device, so that the target cockpit display device deserializes the serialized test video data according to the first deserializer to obtain the test video data, performs a display test according to the test video data, and outputs a test video data stream.

[0048] When the video board sends test video data to the target cockpit display device, it can first serialize the test video data through the first serializer. The first serializer matches the first deserializer in the target cockpit display device. Therefore, the target cockpit display device can deserialize the serialized test video data according to the first deserializer to obtain the test video data, and then output the test video data stream.

[0049] In an embodiment of the present application, by setting a first serializer in the video board that matches the first deserializer in the target cockpit display device, data transmission between the video board and the target cockpit display device can be supported. In addition, the video board can support the detection of different models of cockpit display devices by replacing serializers of different signals. It is only necessary to ensure that the serializer matches the deserializer of the cockpit display device, thereby reducing the cost of detecting cockpit display devices with different signals.

[0050] Figure 3 This is a flowchart of a cockpit display device detection method according to another embodiment of the present application. Figure 3 As shown, the test data includes a test video data stream output by a target cockpit display device. Correspondingly, the cockpit display device detection method includes the following steps:

[0051] Step 301: Generate a control video data stream according to the test video data stream.

[0052] Step 302: Compare the test video data stream output by the target cockpit display device with the control video data stream to determine a comparison result.

[0053] Step 303: Send the comparison result to the host computer, so that the host computer determines the detection result of the target cockpit display device according to the comparison result.

[0054] The test data received by the video board may include a test video data stream output by a target cockpit display device. In this scenario, the host computer sends a video test instruction to the target cockpit display device. The target cockpit display device generates a test video data stream according to the video test instruction and sends it to the video board. The video board generates a control video data stream according to the test video data stream, and compares the control video data stream with the test video data stream to obtain a comparison result. Since the comparison method of the video board is a simple logical comparison, the video board sends the comparison result to the host computer. Certain judgment logic can be stored in the host computer to determine whether the detection result of the target cockpit display device is passed or failed according to the comparison result.

[0055] In an embodiment of the present application, a video test instruction is sent by a host computer to a target cockpit display device, and then the target cockpit display device sends the generated test video data stream to a video board, which can further ensure the homology of the data stream generated by the video board and the target cockpit display device, thereby improving the detection accuracy of the cockpit display device.

[0056] In a possible implementation, the process of generating a control video data stream according to the test video data stream may further include:

[0057] The test video data stream is deserialized by a second deserializer, wherein the second deserializer matches a second serializer in a target cockpit display device. A control video data stream is generated according to the deserialized test video data stream.

[0058] When the target cockpit display device sends a test video data stream to the video board, it can be serialized through the second serializer, so the video board can deserialize through the second deserializer matching the second serializer to obtain the test video data stream.

[0059] In the embodiment of the present application, by providing a second deserializer in the video board that matches the second serializer in the target cockpit display device, data transmission between the video board and the target cockpit display device can be supported.

[0060] Figure 4 This is a schematic diagram of a cockpit display device detection system according to an embodiment of the present application. Figure 4 As shown, the cockpit display device detection system 400 includes: a host computer 401 and a video board 402.

[0061] The video board 402 is used to perform operations corresponding to the cockpit display device detection method in the above embodiment. The host computer 401 is used to receive the comparison result sent by the video board 402 and determine the detection result of the target cockpit display device 600 according to the comparison result.

[0062] In order to understand whether the target cockpit display device 600 can display normally, the video board 402 will generate a control video data stream based on the received test data to compare with the test video data stream output by the target cockpit display device 600. Since the comparison method of the video board 402 is a simple logical comparison, the video board 402 sends the comparison result to the host computer 401. A certain judgment logic can be stored in the host computer 401 to determine whether the detection result of the target cockpit display device 600 is passed or failed based on the comparison result.

[0063] It should be noted that the data used for the test video data stream output by the target cockpit display device 600 is the same as the data used by the video board 402 to generate the control video data stream.

[0064] Specifically, when the comparison result indicates that the similarity between the control video data stream output by the video board and the test video data stream output by the target cockpit display device 600 is higher than a preset similarity threshold, the host computer 401 determines that the detection result of the target cockpit display device 600 is passed, and the similarity threshold may be 95%.

[0065] In the embodiment of the present application, the video board 402 and the target cockpit display device 600 generate video data streams respectively, so that the video board 402 can realize automatic comparison, and then the detection result of the target cockpit display device 600 is judged according to the comparison result through the host computer 401, with high accuracy and detection efficiency.

[0066] In a possible implementation, the host computer 401 is used to send a video test instruction to the video board 402. The video board 402 is used to generate test video data according to the video test instruction, generate a control video data stream according to the test video data, and perform a display test on the target cockpit display device 600 according to the test video data, so that the target cockpit display device 600 outputs the test video data stream.

[0067] The test data received by the video board 402 may be a video test instruction sent by the host computer 401. In this scenario, the host computer 401 does not need to communicate with the target cockpit display device 600. The video board 402 directly generates test video data according to the video test instruction, generates a control video data stream according to the test video data, and performs a display test on the target cockpit display device 600 according to the test video data. The target cockpit display device 600 will output the test video data stream to the video board. The video board 402 compares the test video data stream output by the target cockpit display device 600 with the control video data stream, and can determine the comparison result.

[0068] In the embodiment of the present application, by directly sending a video test instruction to the video board 402 by the host computer 401, the data processing pressure of the target cockpit display device 600 can be reduced, thereby improving the detection efficiency.

[0069] In a possible implementation, the host computer 401 is used to send a video test instruction to the target cockpit display device 600, so that the target cockpit display device 600 generates a test video data stream according to the video test instruction, and sends the test video data stream to the video board 402. The video board 402 is used to generate a control video data stream according to the test video data stream.

[0070] The test data received by the video board 402 may include a test video data stream output by the target cockpit display device 600. In this scenario, the host computer 401 sends a video test instruction to the target cockpit display device 600. The target cockpit display device 600 generates a test video data stream according to the video test instruction and sends it to the video board 402. The video board 402 generates a control video data stream according to the test video data stream, and compares the control video data stream with the test video data stream to obtain a comparison result.

[0071] In an embodiment of the present application, a video test instruction is sent to the target cockpit display device 600 by the host computer 401, and then the target cockpit display device 600 sends the generated test video data stream to the video board 402, which can further ensure the homology of the data generated by the video board 402 and the data stream generated by the target cockpit display device 600, thereby improving the detection accuracy of the cockpit display device 600.
