一个精确测量圆环宽度的halcon程序

效果图

1. * Image Acquisition 01: Code generated by Image Acquisition 01
   
2. read_image (Image, 'D:/images/ring.png')
   
3. rgb1_to_gray (Image, GrayImage)
   
4. dev_set_draw ('margin')
   
5. median_image (GrayImage, ImageMedian, 'circle', 3, 'mirrored')
   
6. threshold (ImageMedian, Region, 0, 50)
   
7. gen_contour_region_xld (Region, outContours, 'border')
   
8. fill_up (Region, RegionFillUp)
   
9. *获取内部白色区域
   
10. difference (RegionFillUp, Region, RegionDifference)
    
11. gen_contour_region_xld (RegionDifference, inContours, 'border')
    
12. count_obj (inContours, Number)
    
13. *dev_display(Image)
    
14. dev_set_color('green')
    
15. dev_display(inContours)
    
16. *calculate the distance from the pionts in the inner contour to the outer contour
    
17. get_contour_xld (inContours, Row, Col)
    
18. distance_pc (outContours, Row, Col, DistanceMin, DistanceMax)
    
19. tuple_max (DistanceMin, maxDistance)
    
20. tuple_min (DistanceMin, minDistance)
    
21. disp_message (3600,'Max '+ minDistance, 'window', 20, 20, 'black', 'true')
    
22. disp_message (3600,'Min '+ maxDistance, 'window', 40, 20, 'black', 'true')

根据大家提供的思路优化升级的程序，其实里面很多算子，自己还不知道具体解释，只知道效果

亲 有原图吗 能不能发上来学习学习 谢谢
