摘要
测距是实现车辆安全系统的关键技术,本文在对路面图片进行数字图像处理的基础上,先对路面区域确定和汽车目标识别进行了算法改进,针对我国汽车常见车型,提出通过对图像进行等效变换,实现洲量前车距离的新算法,根据实测数据,确定出相关测量系数,并给出了实验结果。
Moving vehicle distance measurement is one of the key technology for road safety. This article proposed one method to detect vehicle distance by using the digital image processing technology. After a series of image preprocesses of the gathered picture, the road surface region recognition and the automobile goal extraction improvement are conducted. Targeting the common types of vehicles road, equivalent transformation method is used, vehicle profile ahead is detected, and a new method is proposed to measure the moving vehicle distance. Experimental data and images are gathered and processed, the result is given.
