案例四：條碼
算子介紹：create_bar_code_model（）創建條形碼模型算子
find_bar_code（）識別條形碼算子
create_data_code_2d_model（）創建二維碼模型
find_data_code_2d（）識別二維碼
read_image(C79iJtv5yGZq36Gm3g, '1.png')
rgb1_to_gray (C79iJtv5yGZq36Gm3g,GrayImage)
*創建條碼模型
create_bar_code_model([], [], BarCodeHandle)
*條碼識別
find_bar_code(GrayImage, SymbolRegions1, BarCodeHandle, 'auto', DecodedDataStrings3)
disp_message(3600, DecodedDataStrings3, 'window', 12, 12, 'black', 'true')
*二維碼識別
read_image (Image,'2-UTF-8.png')
rgb1_to_gray(Image, GrayImage1)
*創建二維碼模型
create_data_code_2d_model('QR Code', [], [], DataCodeHandle)
*二維碼識別
find_data_code_2d(GrayImage1, SymbolXLDs2, DataCodeHandle, 'train', 'all', ResultHandles2,DecodedDataStrings)
disp_message(3600, DecodedDataStrings, 'window', 12, 12, 'black', 'true')
read_image(Image1, '3-GB2312.png')
rgb1_to_gray(Image1, GrayImage2)
find_data_code_2d(GrayImage2, SymbolXLDs1, DataCodeHandle, 'train', 'all', ResultHandles1,DecodedDataStrings2)
disp_message(3600, DecodedDataStrings2, 'window', 12, 12, 'black', 'true')
*清楚模型
clear_bar_code_model(BarCodeHandle)
clear_data_code_2d_model(DataCodeHandle)
