摘　　要：测距是提高车辆安全性的关键技术,本文研究了测距系统硬件的组成和图像测距算法,就如何通过数字图像处理技术获得与前车的距离值,并将该值通过CAN总线传送到汽车主控单元中显示进行了讨论,完成了系统的总体和各模块设计,为避免汽车追尾事故的发生提供了一个可行性方案。Moving vehicle distance measurement is one of the key technology for vehicle safety.The article discussed the compose of system hardware and the method of image distance measurement. Mainly discussed the way to detect vehicle distance by using the digital image processing technology, and send the distance data to the main control to display unit via CAN bus. The design of the whole system and the modules is completed, and provide a useful scheme for vehicle collision avoidance.
