我在linux上运行tesseract-ocr引擎时遇到问题.我已经下载了RUS语言数据并将其放到tessdata目录(/ usr/local/share/tessdata).当我尝试使用命令运行tesseract时tesseract blob.jpg out -l rus,它会显示错误:
Error opening data file /usr/local/share/tessdata/eng.traineddata
Please make sure the TESSDATA_PREFIX environment variable is set to the parent directory of your "tessdata" directory.
Failed loading language eng
Tesseract couldn't load any languages!
Could not initialize tesseract.
根据编译指南,我曾经export TESSDATA_PREFIX='/usr/local/share/'
指向我的tessdata目录.也许我应该编辑任何配置文件？Tesseract尝试加载'eng'数据文件而不是'rus'.
