All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
As described in the related art, the related art has problems of high test cost and low test efficiency. For example, fig. 2 shows a schematic diagram of a conventional test scheme, where a camera collects a specific physical scene, and video input signals collected by the camera are divided into 2 cases: in case 1, the video input signal is directly input to the intelligent driving domain controller; in the 2 nd case, the video input signals are processed by the real vehicle cabin domain controller, synthesized and then input to the intelligent driving domain controller. After receiving video signal input, the intelligent driving domain controller is processed by the processor, and video output signals are output through an output interface, and the intelligent driving domain controller comprises: in the 1 st case, the video output signal is directly output to drive the display screen to display; in the 2 nd case, the video output signals are synthesized and output to drive the display screen to display after being processed by the real vehicle cabin domain controller. Finally, the display content of the display screen is checked by manual visual inspection, or the display content of the display screen is shot by an industrial camera vision system, so that the video signal input and output function test of the intelligent driving domain controller is realized.
However, the traditional test scheme requires a camera to shoot a specific real object scene, the required equipment space is large and the cost is high, one camera can usually shoot only one fixed scene, the test coverage is limited, moreover, the intelligent driving domain controller is provided with a ranging single camera and a binocular camera which are long-focus long-distance cameras, the intelligent driving domain controller is easily limited by the conditions of a production and manufacturing site, the actual distance scene cannot be simulated, the shot picture is unclear, and the test quality and the cost are affected. In addition, the traditional test scheme also needs to rely on cabin domain controllers and display screens matched with intelligent driving domain controllers in real vehicles as test accessories, the test accessories are used as products developed by new vehicles in the same period, and some test accessories need to be purchased from the same row or competitors, so that the problems of difficult acquisition, long period and high price exist; along with the trend of large-screen and multi-screen display of the vehicle-mounted display screen, the display screen is larger and larger in size and irregular in shape, and great challenges are brought to the structure and space design of the test system; in the production test process, if the video signal input and output functions are abnormal, the problem of the intelligent driving domain controller product itself or the problem caused by the cabin domain controller and the display screen accessories cannot be directly positioned, and the production efficiency is affected. In addition, if the traditional test scheme adopts a scheme of manually and visually checking the display screen, the risk of misjudgment or missed judgment of personnel cannot be avoided.
Therefore, the application provides a video signal testing method of a domain controller, which is characterized in that a first video signal is acquired, wherein the first video signal is a video signal which is acquired by a camera shooting assembly in a preset testing mode and is received by a video input end, the video testing mode can be switched according to different scene testing requirements, and the problem that the long focus and the short focus of a camera lens are limited by scene space is not required to be considered; and determining the functional state of the video signal input and output function of the domain controller based on the first analysis result data and the second analysis result data, so that the testing accessory such as a display screen is not needed in a video signal loop-back testing mode, the testing cost is reduced, the abnormal problem caused by the testing accessory is effectively avoided, the abnormal functional range can be quickly locked, and the testing efficiency is improved.
