Description

Technical Field

[0001] The embodiments of the present invention relate to the field of panoramic display technology, and in particular to a display function testing device and system. Background Art

[0002] As the number of family cars continues to increase, collisions and scratches often occur. Car owners pay more and more attention to driving safety. For this reason, the 360-degree panoramic imaging system, also known as the satellite panoramic driving safety system, was born, which can observe the situation around the car in a panoramic view. The existing 360-degree panoramic imaging system collects images around the vehicle based on the front, rear, left and right four cameras. After unit distortion restoration-viewing angle conversion-image stitching-image enhancement image processing, a seamless 360-degree panoramic bird's-eye view of the vehicle is finally formed on the car display screen. While displaying the panoramic view, a single view of any party can also be displayed. In the single view in front and behind the car, there are marked track auxiliary lines to locate the position and distance of obstacles, and predict the vehicle's driving path, improving parking safety and efficiency. The driver can monitor the front, rear, left and right video images outside the car in real time in the car to avoid accidents and drive the vehicle more intuitively and safely.

[0003] The existing 360 panoramic products are developed and designed according to different car models, mainly involving CAN protocol and imaging. The 360 ​​panoramic products convert the YUV656 or 601 signals collected by the camera into RGB signals through the main control IC. The RGB signals are output as FPD-Link III interface signals through the serializer IC, and the data is transmitted to the vehicle display screen through coaxial or shielded twisted pair (STP) cables. The original vehicle display screen restores the FPD-Link III interface signals into RGB signals through the deserializer IC, and displays the 360 ​​panoramic images on the original vehicle screen. The serializer IC on the 360 ​​panoramic product and the deserializer IC on the original vehicle display screen need to be used in pairs.

[0004] In the process of developing 360-degree panoramic display products, both functional testing and aging testing require display images. However, because the serializer IC of each product is different, the display device required for testing is also different. If the original car screen is directly used as the display device, the testing cost will be greatly increased. The existing display function test device is not universal for display products of different models and is inconvenient to use. Summary of the invention
