More Information
Summary:The invention discloses a deceleration strip identification method, comprising the main identification steps: acquiring a road image by a vehicle-mounted camera; preprocessing the acquired image; segmenting the image by using an Otsu method; extracting the edge of the deceleration strip in the image by adopting an improved canny algorithm; extracting a straight line where the deceleration strip ispossibly located through hough transformation and angle screening; and determining a straight line where the deceleration strip is located through extraction of the gray blocks. By means of the deceleration strip identification method, the driverless vehicle can be helped to quickly and accurately recognize the deceleration strip on the road, and deceleration processing can be conveniently conducted in time, and technical support is provided for popularization of the driverless vehicle. 本发明公开一种减速带的识别方法，主要识别步骤为：车载摄像头获取道路图像；对采集的图像进行预处理；使用大津法对图像进行分割；采用改进的canny算法提取图像中减速带的边缘；通过hough变换以及角度的筛选提取减速带可能所在的直线；通过灰度块的提取确定减速带所在的直线
