| 摘 要： | 提出一种高分辨率遥感影像中操场跑道的自动识别方法。在分析操场跑道结构特征的基础上,采用改进的Hough变换方法提取操场跑道圆弧形边缘;然后结合识别出的圆弧形结构信息识别与之相连的直线形边缘;最后对识别出的操场跑道进行细化和修剪处理,实现操场跑道的自动识别。

| Abstract: | A method is proposed to extract the playground racetrack in high resolution remote sensing image automatically in this article. Based on the structure of playground racetrack an improved hough transform is firstly utilized to detect the arc-shaped edge of the target. Secondly, the straight-edge is identified according to the outcome of arc-shaped edge. Finally, the refinement and pruning is completed and the results are validated. |
