halcon 自带的字符库'Pharma.omc'和  'DotPrint.omc'

\**********申明字符数组，将0-9和A-Z赋值**********************/
CharH := []
for i := 0 to 9 by 1
   CharH[i] := chr(round(i + ord('0')))
endfor
for i := 10 to 36-1 by 1
   CharH[i] := chr(round(i-10 + ord('A')))
endfor
NumChar := |CharH|


\**********申明一个训练文件, 后缀名是.trf***=*******************/
TrainFile := 'E:\Halcon学习资料\s.trf'


\**********将训练文件与图像关联***=*******************/
for i := 1 to NumChar-1 by 1
select_obj(Image, SingleWord, i)
append_ocr_trainf(SingleWord, Image, CharH[i], TrainFile)
endfor

/*****************制作OCR识别文件********************/
