Design of intelligent cockpit domain controller FPD-Link Ⅲ detection system
摘要
Abstract
With the progression of automotive electronic technology,FPD-Link Ⅲ,as a high-speed serial video transmission interface,is extensively employed in intelligent cockpit systems.In order to conduct its examination,a FPD-Link Ⅲ video processing solution based on the DS90UB948 unstring chip is proposed.In this system,ZYNQ is used as the processing unit to compress,splice,and output the parallel signals output by the unstring chip.The output splice video stream is used for real-time display.The collected single image is used for quality detection,and the image similarity algorithm is used for the quantitative analysis.The experimental results show that the system can receive and process three channels of FPD-Link Ⅲ video streams correctly,providing coherent and smooth spliced images along with clear captured images.The SSIM image similarity algorithm can accurately locate abnormal paths,meet the quality verification requirements of FPD-Link Ⅲ,and provide technical support and guarantee for image acquisition and transmission of the construction of high-level intelligent driving simulation test platform.关键词
