Tesseract OCR 对于低分辨率或模糊的图片可能无法准确识别。尝试使用更高分辨率和清晰度的图片来提高识别结果的准确性。对于 Mac 上的截图一般都是很清晰的所以这个缺点影响不大。
在 Mac 上使用官网推荐的方式安装
brew install tesseractThe tesseract directory can then be found using brew info tesseract, e.g.
/usr/local/Cellar/tesseract/5.3.2/bin/tesseractdemo:
import pytesseract
from PIL import Image# 可以写一个函数 crop_picture 将原图裁剪一下只保留想要识别文本的部分这样识别更加准确一些。
