PytesseractOCR多配置选项

我有pytesseract的一些问题.我需要将Tesseract配置为配置为接受单个数字,同时也只能接受数字,因为数字零通常与"O"混淆.

像这样:

target = pytesseract.image_to_string(im,cOnfig='-psm 7',cOnfig='outputbase digits')

非常感谢,

尼尔

tesseract-4.0.0a支持如下psm.如果要进行单字符识别,请设置psm = 10.如果您的文本仅包含数字,则可以设置tessedit_char_whitelist=0123456789.

Page segmentation modes:
  0    Orientation and script detection (OSD) only.
  1    Automatic page segmentation with OSD.
  2    Automatic page segmentation, but no OSD, or OCR.
  3    Fully automatic page segmentation, but no OSD. (Default)
  4    Assume a single column of text of variable sizes.
  5    Assume a single uniform block of vertically aligned text.
  6    Assume a single uniform block of text.
  7    Treat the image as a single text line.
  8    Treat the image as a single word.
  9    Treat the image as a single word in a circle.
 10    Treat the image as a single character.
 11    Sparse text. Find as much text as possible in no particular order.
 12    Sparse text with OSD.
 13    Raw line. Treat the image as a single text line,
                        bypassing hacks that are Tesseract-specific.

以下是image_to_string具有多个参数的示例用法.

target = pytesseract.image_to_string(image, lang='eng', boxes=False, \
        cOnfig='--psm 10 --oem 3 -c tessedit_char_whitelist=0123456789')

希望这可以帮助.

这不是一个新问题.它是您的解决方案的后续,它直接推断您提供的内容.如果你想提到你曾经使用白色列表参数的tesseract版本会有所帮助.请再次阅读我的评论,你会明白的.

你能告诉我这个`pyt.image_to_data（im_gray_res，lang =&＃39;eng&＃39;，cOnfig=&＃39;-psm 11 --oem 3 -c tessedit_char_whitelist = ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789&＃39;）是什么问题吗？我在限制字符的搜索域时遇到了很多麻烦。
