1. read_image (Image0, 'D:/个人/5/裂纹20260123.png')
   
2. rgb1_to_gray (Image0, Image0)
   
3. mean_image (Image0, Image, 3, 3)
   
4. scale_image_max (Image, Image)
   
5. 
   
6. *提取有效区域
   
7. threshold (Image, RegionB, 0, 87)
   
8. connection (RegionB, RegionB)
   
9. select_shape_std (RegionB, RegionB, 'max_area', 70)
   
10. erosion_circle (RegionB, RegionB, 10)
    
11. 
    
12. *提取缺陷区域
    
13. local_threshold (Image, Region, 'adapted_std_deviation', 'dark', ['mask_size','scale','range'], [15,0.1,128])
    
14. connection (Region, Region)
    
15. select_shape (Region, RegionS, 'area', 'and', 5, 9999999)
    
16. *//把你画的红框去掉
    
17. union1 (RegionS, RegionS)
    
18. closing_circle (RegionS, RegionS, 3.5)
    
19. connection (RegionS, RegionS)
    
20. select_shape (RegionS, RegionS, 'width', 'and', 0, 40)
    
21. 
    
22. intersection (RegionB, RegionS, RegionS)
    
23. 
    
24. dev_clear_window ()
    
25. dev_display (Image)
    
26. dev_set_draw ('margin')
    
27. dev_set_color ('green')
    
28. dev_display (RegionB)
    
29. dev_set_color ('red')
    
30. dev_display (RegionS)
