halcon学习笔记——实例篇 长度和角度测量
实例二：长度和角度测量 素材图片：
halcon代码：
1: *读取并截取图片 2: dev_close_window()
3: read_image (Image, 'D:/MyFile/halcon/长度和角度测量/图.png') 4: crop_rectangle1 (Image, ImagePart, 75, 0, 400, 400) 5: get_image_size (ImagePart, Width, Height)
6: dev_open_window (0, 0, Width, Height, 'black', WindowHandle) 7: dev_display (ImagePart) 8:
9: *获取图形的边界
10: threshold (ImagePart, Regions, 0, 112) 11:
12: *分离三角形和圆形
13: connection(Regions,ConnectedRegions)
14: sort_region(ConnectedRegions,SortedRegions,'upper_left','true','column') 15: select_obj(SortedRegions,Circle,1) 16: select_obj(SortedRegions,Triangle,2) 17:
18: *获取三角形各边的信息
19: skeleton(Triangle,TriangleSkeleton)
