摘　　要：提出了一种基于连通区域选择的导航线特征点确定算法。首先在传统农业图像分割的基础上选取面积最大的连通区域。然后通过开操作去除连通区域边界的毛刺,再逐行提取图像的特征点。对25幅图像分别按传统方法、未进行开操作的连通区域选择法,进行开操作的连通区域选择法进行导航线特征点提取。统计分析结果表明与传统方法比较进行开操作的连通区域选择法的特征点误差显著降低。A guidance directrix feature point extraction algorithm is proposed which is based on connected do- main selection. The biggest connected domain is first selected from the agriculture segmentation image which is seg- mented with traditional method. And then the edge spur of connected domain is reduced with open operation. The feature point is extracted from every line in connected domain. 25 images are processed with 3 methods including traditional method, connected domain selection method without open operation and connected domain selection method with open operation. The statistic analysis of the results shows that the errors of the connected domain selec- tion method with open operation are obviously reduced compared with traditional method.
