摘　　要：针对市场上倒车雷达或倒车影像的局限性,提出基于字符视频叠加技术的倒车辅助系统的设计方案。该系统可以采集汽车行驶中所涉及的参数,通过视频叠加显示,并且应用小波理论、温度补偿和盲区控制等方法提高测距的精度。Reversing radar or reverse images used currently in the market is limited to an independent view ranging signal or video signals,this paper presents the design of reversing assistance system based on character-video overlapping technology.When vehicle moving,the involved parameters are collected,and overlapped to display on the video.With the method of wavelet theory,temperature compensation and blind control,the precision of ranging is improved.

关 键 词：字符视频叠加 超声波 测距 小波理论
