一、安裝tesseract-ocr
- 各版本tesseract：Index of /tesseract (uni-mannheim.de)
- 預設安裝路徑：C:\Program Files (x86)\Tesseract-OCR
二、安裝opencv-python【可略】
python --version
pip install opencv-python
pip install pytesseract
三、安裝語言包tessdata_best
tessdata_best：tesseract-ocr/tessdata_best: Best (most accurate) trained LSTM models. (github.com)下載：chi_tra.traineddata
貼至(預設路徑)：C:\Program Files\Tesseract-OCR\tessdata
四、環境配置
新增【TESSDATA_PREFIX】環境變數
- C:\Program Files\Tesseract-OCR\tessdata
環境變數PATH 新增
- C:\Program Files\Tesseract-OCR\tessdata
- C:\Program Files\Tesseract-OCR
五、確認tesseract是否安裝成功
命令提示字元：tesseract
版本： tesseract --version
列出語言包：tesseract --list-langs
備註：環境變數更動後須重新開機才會啟用設定
