| 摘 要： | 针对高分辨率航空影像的特点,提出了基于角点检测的建筑物轮廓矢量化方法:首先,对航空影像进行多尺度面积形态学分割,获取建筑物的二值图像；其次,利用边缘跟踪技术,记录边缘点,在边界曲线上利用高斯函数计算其曲率,提取候选角点集,并由自适应支持区域确定的角点角度和一个动态曲率阔值代替固定的阈值筛选出正确角点；最后,以直角作为约...

| Abstract: | In this paper,a novel vectorization algorithm of building' contours is proposed:firstly,the multi-scale area morphological segmentation is carried out on the aerial imagery and the binary image is generated;secondly,the edge points are recorded by applying the edge tracking technology,according to the curvature calculated at a fix low scale of Gaussian filter for each point of the contour,the corner candidates are obtained;then,angles of corner candidates checked in an adaptive region of support and a dynam... |
