Barcode train code 128

Hello,
I used HALCON 13 for barcode controller but it doesn't work well. (It didn't find any barcode in image list on below.)

Codes:
*************
create_bar_code_model ([], [], BarCodeHandle)
set_bar_code_param (BarCodeHandle, 'train', 'all')

for Index := 1 to 2 by 1
    read_image (Image, 'test' + Index + '.jpg')
    find_bar_code (Image, SymbolRegions, BarCodeHandle, 'Code 128', DecodedDataStrings)
endfor

************

may be your image resolution not enough!
only this image can be decoded on beblow


my codes:

1. dev_set_draw ('margin')
   
2. set_display_font (3600, 20, 'mono', 'true', 'false')
   
3. create_bar_code_model ([], [], BarCodeHandle)
   
4. *set_bar_code_param (BarCodeHandle, 'train', 'all')
   
5. 
   
6. for Index := 1 to 2 by 1
   
7.     read_image (Image, 'test' + Index + '.jpg')
   
8.     draw_rectangle2 (3600, Row, Column, Phi, Length1, Length2)
   
9.     gen_rectangle2 (Rectangle, Row, Column, Phi, Length1, Length2)
   
10.     decode_bar_code_rectangle2 (Image, BarCodeHandle, 'auto', Row, Column, Phi, Length1, Length2, DecodedDataStrings)
    
11.     disp_message (3600, DecodedDataStrings, 'window', 12, 12, 'green', 'true')
    
12.     stop()
    
13. *    find_bar_code (Image, SymbolRegions, BarCodeHandle, 'auto', DecodedDataStrings)
    
14. endfor

I tried your codes on HALCON 13. But it didn't find any barcodes. Which version of HALCON do you use?
Thanks for information.

Halcon 12.0.3

Well,
Does anybody have any ideas for

1. [set_bar_code_param] and  [set_bar_code_param_specific]

复制代码

settings?
Thanks.

敢问 这个为什么不是创建条码模型直接create_bar_code_model ([], [], BarCodeHandle)然后直接find_bar_code (Image, SymbolRegions, BarCodeHandle, 'Code 128', DecodedDataStrings)呢？

他是要用训练模式去识别条码，而且这个条码确实不容易识别出来！
而且直接根据条码模型去识别也识别不出来，不信你试试看，应该是分辨率不够！
