起飞页怎么做网站网页制作的基本步骤

Tesseract OCR 引擎：Tesseract是一个开源的OCR引擎，你需要先安装它。可以从Tesseract官方网站（https://github.com/tesseract-ocr/tesseract）下载适用于你的操作系统的安装程序或源代码，并按照官方文档进行安装。

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 tesseract

The tesseract directory can then be found using brew info tesseract, e.g.

/usr/local/Cellar/tesseract/5.3.2/bin/tesseract

demo:

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。
