上位机HALCON视觉通过区域快速获得圆半径与圆心

简单阈值分割后，求最大内接圆，便可

1. dev_close_window ()
   
2. read_image (image, '1.jpg')
   
3. dev_open_window(0, 0, 512, 512, 'black', WindowHandle)
   
4. rgb1_to_gray(image,gray)
   
5. dev_display (gray)
   
6. threshold (gray, Regions, 120, 255)
   
7. inner_circle(Regions,Row,Column, Radius)
   
8. dev_clear_window()
   
9. dev_set_draw('margin')
   
10. dev_display(image)
    
11. disp_arrow(WindowHandle,Row, Column, Row+Radius*sin(deg(-135)), Column+Radius*cos(deg(-135)), 1)
    
12. 
    
13. gen_circle(Circle, Row, Column, Radius)
    
14. gen_cross_contour_xld(Cross, Row, Column, 6, 0)
    
15. Message:='坐标:'+Row+' ,'+Column
    
16. Message[1] := '半径:'+Radius
    
17. disp_message (WindowHandle, Message, 'image', Row, Column+Radius, 'black', 'true')
