我正在使用tess4j,Tesseract的java包装器.我也安装了正常的Tesseract.我不确定tess4j是如何工作的,但由于它附带了一个tessdata文件夹,我可以假设您将语言数据文件放在那里.但是,tess4j仅在语言数据文件位于“真实”tessdata文件夹(tesseract附带的文件夹,而不是tess4j)中时才起作用.如果我删除该文件夹,我收到此错误消息：

Error opening data file C:\Program Files\Tesseract-OCR\tessdata/jpn.trained

data

Please make sure the TESSDATA_PREFIX environment variable is set to the par

ent directory of your "tessdata" directory.

Failed loading language 'jpn'

Tesseract couldn't load any languages!

这是否意味着我需要安装Tesseract才能使用tess4j？为什么？或者maby我的tess4j tessdata文件夹位于错误的位置(目前我的.java文件中,tess4j jars位于我设置了类路径的lib文件夹中).
