基于MATLAB图像处理的非结构化道路识别

摘要

In this article ,the color images of unstructured road was identified in the color space by use of MATLAB image processing toolbox .Firstly ,the image was segmented by Otsu method in color space .Secondly ,the image was denoised through mathematical morphology and threshold value area expunction .Thirdly ,the road edge was detected with Roberts operator .Finally ,a smooth road boundary curve could be fitted by means of the least square method .%应用MATLAB图像处理工具箱，针对非结构化道路的彩色图像，在颜色空间对道路进行识别处理。首先在颜色空间中使用Otsu法（大津法）对道路图像进行分割，再利用数学形态学和阀值面积消去法对图像进行去噪处理，然后利用Roberts算子检测出道路边缘，最后利用最小二乘法对图像进行曲线拟合，得到平滑的道路边界曲线。
