tesseract-4.0.0a支持下面
psm。如果要具有单个字符识别，请设置
psm =10。并且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.
这是
image_to_string带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。
