问题描述
我使用Tessnet2组件（它使用的tesseract）做OCR。不幸的是，PROGRAMM崩溃后不我调用init方法的任何异常：
I'm using the Tessnet2 assembly (which uses Tesseract) to do OCR. Unfortunately the programm crashes without any exception after I call the init method:
tessnet2.Tesseract ocr = new tessnet2.Tesseract();
ocr.Init(@"D:\Test\Tessdata\german", "deu", false);
德国文件夹包含以下的tesseract 2字数据：
The german folder contains the following tesseract 2 word data:
- deu.DangAmgigs
- deu.freq-耶
- deu.inttemp
- deu.normproto
- deu.pffmtable
- deu.unicharset
- 申。用户字
- deu.word-耶
- deu.DangAmgigs
- deu.freq-dawg
- deu.inttemp
- deu.normproto
- deu.pffmtable
- deu.unicharset
- deu.user-words
- deu.word-dawg
如果我用空，因为我在我的机器上安装的tesseract它工作正常的路径。不过，我需要与路径的解决方案，因为那里的PROGRAMM将deplyoed它没有保证的tesseract安装。
If I use null for the path it works fine because I installed tesseract on my machine. However I need a solution with the path because where the programm will be deplyoed it is not ensured that tesseract is installed.
推荐答案
现在的问题是，如果你有安装的tesseract有一个环境变量集（ TESSDATA_PREFIX ），其中包含tessdata的路径。要使用自己的道路，有必要的tesseract卸载和删除的环境变量。
The problem is that if you have Tesseract installed there is an environment variable set ( TESSDATA_PREFIX )which contains the path of the tessdata. To use your own path it is necessary to uninstall Tesseract and delete the environment variable.
