The invention discloses a reversing video fixation detection system, a detection method and a system anomaly detection method in the technical field of reversing imaging, and the reversing video fixation detection system comprises a Camera System which is a reversing camera system and is used for collecting a reversing video and outputting a GVIF3 signal, the Camera System is connected with an ADAS, the ADAS is used for carrying out video synthesis processing and sending the processed reversing video to an AVN, and the ADAS is connected with the AVN. The camera system sends collected videos to the ADAS, the ADAS synthesizes the videos in the camera system and sends the synthesized videos to the AVN, and the AVN detects a video source input by the ADAS and displays an image. The AVN comprises an SOC chip AC8025 with a rapid CRC (cyclic redundancy check) function, and is used for processing, displaying and imaging a fixed video. According to the invention, the problems of risks caused by no fixation detection of the reversing video, no risk prompt after the reversing fixation is detected, poor driving experience caused by frequent fixation of the reversing video due to AVN video processing, and incapability of continuing fixation detection due to no abnormal error reporting mechanism of the AVN video processing module are solved.

    本发明公开了倒车成像技术领域内的倒车视频固着检测系统、检测方法及系统异常检测方法,倒车视频固着检测系统,包括Camera System,为倒车摄像头系统,用于采集倒车视频,输出GVIF3信号,Camera System与ADAS相连,ADAS用于视频合成处理,将处理后的倒车视频发给AVN,ADAS与AVN相连。Camera System将采集到视频发送给ADAS,ADAS将Camera System中视频进行合成,并发送给AVN,AVN检测ADAS输入的视频源并显示成像。AVN包含具备快速CRC检验的SOC芯片AC8025,并对固着的视频进行处理和显示成像。解决了倒车视频无固着检测带来的风险难题、检测到倒车固着后但没有风险提示问题、因AVN视频处理造成倒车视频频繁固着导致驾驶体验较差的难题,以及因AVN视频处理模块无异常报错机制导致无法继续进行固着检测的问题。
