执行代码:
import cv2
import pytesseract
img = cv2.imread('1d.png')
print(pytesseract.image_to_string(img))
报错信息:
raise TesseractNotFoundError()
pytesseract.pytesseract.TesseractNotFoundError: tesseract is not installed or it's not in your path
问题原因:
使用pip安装了pytesseract
,但忘记安装tesseract二进制文件。
1、Linux上安装命令
sudo apt update
sudo apt install tesseract-ocr
sudo apt install libtesseract-dev
2、Mac安装命令
brew install tesseract
3、Windows上安装命令
从https://github.com/UB-Mannheim/tesseract/wiki下载二进制文件。然后添加pytesseract.pytesseract.tesseract_cmd = 'C:\\Program Files (x86)\\Tesseract-OCR\\tesseract.exe'
到脚本中。(如有必要,须替换tesseract二进制文件的路径)
参考文档: https://pypi.org/project/pytesseract/(安装部分)和 https://github.com/tesseract-ocr/tesseract/wiki#installation
