摘要
随着汽车电子技术的进步,FPD-Link Ⅲ作为高速串行视频传输接口,正广泛应用于智能座舱系统.为对其进行检测,提出一套基于DS90UB948解串芯片的FPD-Link Ⅲ视频处理方案.系统采用ZYNQ作为处理核心,对解串芯片输出的并行信号进行图像压缩拼接和输出,输出的拼接视频流用于实时显示.采集的单路图像用于质量检测,通过图像相似度算法进行定量分析.实验结果表明:系统可正确接收、处理三路FPD-Link Ⅲ视频流,拼接图像连贯流畅,采集图像清晰;并且SSIM图像相似度算法可准确定位异常通路,满足了FPD-Link Ⅲ的质量验证要求,为构建高阶智能驾驶仿真测试平台的图像采集与传输提供了技术支持与保障.
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.
