为了避免倒车过程中因视觉盲区可能出现的安全隐患问题[1][2]，文章采用飞思卡尔单片机做主机，Aptina图像传感器ASX340[3]做从机，利用ASX340内部的OVERLAY位图叠加系统，设计了一种能够将倒车过程中实时的车辆尾部的影像，距离障碍物的安全距离，倒车轨迹路径等信息提供驾驶员倒车影像系统[9][10]。使用HYRes3_1、Imatest软件[4]测量了影像图像质量的主要因素。测量结果表明成像质量能够满足目前车厂的要求。

In order to avoid safety hazards during the process of reversing caused by visual blind spot, this paper presents a reversing video system based on Freescale microcontroller as the host, Aptina image sensor as the slave. By using OVERLAY systems inside ASX340, the system puts the overlay bitmap information to the output video display in car DVD, provides the information of real-time car rear image, safety distance to obstacles and reversing trajectory path to drivers. Use HYRes3_1, Imatest imaging software to measure the main factor in image quality. Measurement results show that the image quality meet the requirements of the current depot.
