Under the premise of when the moved distance from the camera to the obstacle is known, based on monocular vision distance measure technology, integrating and using the limited area image fast matching algorithm, an enhanced reversing video system, which can timely measure a rear obstacle distance, is being researched on. Simulation experiment results demonstrate that, the essential technologies that are being researched on possess comparatively high measurement precision and faster response speed, which have laid a good technical foundation for further research, development, promotion and application of products of this system.%在摄像头相对障碍物移动距离可知的前提条件下,基于单目视觉的距离测量技术,结合运用有限局域图像快速匹配算法,研究一种可以实时测量后方障碍物距离的增强型倒车影像系统.模拟实验结果表明,所研究的关键技术具有较高的测量精度和较快反应速度,为该系统产品的深入研发和推广应用奠定了良好的技术基础.
