你提供的jpg图片在halcon中打不开，我把它转换成了bmp格式

1. create_data_code_2d_model ('QR Code', 'default_parameters', 'maximum_recognition', DataCodeHandle)
   
2. dev_get_window (WindowHandle)
   
3. set_display_font (WindowHandle, 20, 'mono', 'true', 'false')
   
4. for Index := 1 to 4 by 1
   
5.     read_image (Image, Index+'.bmp')
   
6.     threshold (Image, Region, 250, 255)
   
7.     fill_up (Region, RegionFillUp)
   
8.     connection (RegionFillUp, ConnectedRegions)
   
9.     select_shape (ConnectedRegions, SelectedRegions, ['area','rectangularity'], 'and', [60000,0.8], [70000,1])
   
10.     shape_trans (SelectedRegions, RegionTrans, 'rectangle2')
    
11.     area_center (RegionTrans, Area, Row, Column)
    
12.     gen_cross_contour_xld (Cross, Row, Column, 26, 0.785398)
    
13.    
    
14.     reduce_domain (Image, RegionTrans, ImageReduced)
    
15.     smooth_image (ImageReduced, ImageSmooth, 'gauss', 0.5)
    
16.     find_data_code_2d (ImageSmooth, SymbolXLDs, DataCodeHandle, [], [], ResultHandles, DecodedDataStrings)
    
17.    
    
18.     *提取二维码准确区域
    
19.     erosion_rectangle1 (RegionTrans, RegionErosion, 11, 11)
    
20.     reduce_domain (Image, RegionErosion, ImageReduced1)
    
21.     threshold (ImageReduced1, Region1, 0, 200)
    
22.     shape_trans (Region1, RegionTrans1, 'rectangle2')
    
23.     area_center (RegionTrans1, Area1, Row2, Column2)
    
24.     gen_cross_contour_xld (Cross2, Row2, Column2, 26, 0)
    
25.    
    
26.     *也可直接用SymbolXLDs求二维码区域中心
    
27. *     area_center_xld (SymbolXLDs, Area1, Row1, Column1, PointOrder)
    
28. *     gen_cross_contour_xld (Cross1, Row1, Column1, 26, 0)
    
29.    
    
30.     dev_display (Image)
    
31.     get_draw (WindowHandle, Mode)
    
32.     dev_set_draw ('margin')
    
33.     dev_set_color ('red')
    
34.     dev_display (RegionTrans)
    
35.     dev_display (Cross)
    
36.     dev_set_color ('green')
    
37.     dev_display (RegionTrans1)   
    
38.     dev_disp_text (DecodedDataStrings, 'image', Row2+10, Column2+10, 'green', [], [])
    
39.     dev_display (Cross2)
    
40.      dev_set_draw (Mode)
    
41.     stop ()
    
42. endfor
