摘要
测距是实现车辆安全系统的关键技术,计算机视觉提供人类视觉的计算模型。在总结国内外已有的车辆测距的理论的基础上,比较了机器视觉中单目视觉和立体视觉测距的优缺点,重点总结了国内已有的基于单目视觉的车距测量方法,并给出了相应的原理及测距模型。最后,给出了每一种方法存在的优点和一些不足,并对未来进行了展望。
Moving vehicle distance measurement is one of the key technology for road satefy,and computer vision provides computational model of human vision.Based on the theory of domestic and foreign vehicle distance measurements,by comparing advantages and disadvantages of monocular vision with what of stereo vision in machine vision,we summarize domestic vehicle distance measurements based on monocular vision,and provide the corresponding principle and location model.At last,we give the merits and demerits of each method,and prospect the future work.
