tesseract/tesjeract 在实例化时导致应用程序崩溃

我想在 Java 中使用 tesseract，因为我需要为我的 ImageJ 插件执行 OCR。因此我使用 Java 包装器“tesjeract”。但是，当我实例化 new Tesjeract("eng") ImageJ 崩溃时没有提供任何信息。

加载库似乎有效，因为当我不实例化 new Tesjeract("eng") 并运行同一插件两次时，第二次我收到 UnsatisfiedLinkError: Native library C :\Windows\System32\tessdll.dll 已在另一个类加载器中加载。

有什么想法，我能做些什么来解决这个问题吗？

如果相关的话，我使用的是 Windows 7 64 位，但已将 ImageJ 配置为使用 32 位 JVM，因为 tesseract 仅作为 32 位 dll 提供。我正在静态块中加载 dll，它们都放置在 C:\Windows\System32 文件夹中。

static
{
    System.loadLibrary("tessdll");
    System.loadLibrary("tesjeract");
}

编辑：

如果发现有人在 c++ 中遇到类似的问题，并且解决方案是语言文件丢失。我想这也是我的情况的问题。

这就是目录的样子（找到此处）：

project.exe
tessdll.dll
tessdata ----- eng.DangAmbigs
            |- eng.freq-dawg
            |- eng.inttemp
            |- eng.normproto
            |- eng.pffmtable
            |- eng.unicharset
            |- eng.user-words
             - eng.word-dawg

ImageJ 配置为使用 C:\Program Files(x86)\Java\jre7\bin\javaw.exe。因此，我将包括 tessdata 文件夹在内的 dll 放在同一目录中，并从 System32 中删除了 dll。尽管如此，应用程序还是崩溃了。

原文

I'd like to use tesseract in Java as I need to perform OCR for my ImageJ plugins. Therefore I am using the Java wrapper "tesjeract". However, when I instantiate new Tesjeract("eng") ImageJ crashes without giving any information.

Loading the libraries seems to be working, because when I don't instantiate new Tesjeract("eng") and run the same plugin twice, the second time I receive an UnsatisfiedLinkError: Native library C:\Windows\System32\tessdll.dll already loaded in another classloader.

Any ideas, what I can do to solve the problem?

In case it is relevant, I'm using Windows 7 64-bit, but have configured ImageJ to use 32-bit JVM, since tesseract is only available as 32-bit dll. I'm loading the dlls in a static block and both of them are placed in C:\Windows\System32 folder.

static
{
    System.loadLibrary("tessdll");
    System.loadLibrary("tesjeract");
}

Edit:

If found out that someone was experiencing a similar problem in c++, and the solution was that the languange files were missing. I suppose that's the problem in my case as well.

This is how the directory should look like ( found here ):

project.exe
tessdll.dll
tessdata ----- eng.DangAmbigs
            |- eng.freq-dawg
            |- eng.inttemp
            |- eng.normproto
            |- eng.pffmtable
            |- eng.unicharset
            |- eng.user-words
             - eng.word-dawg

ImageJ is configured to use C:\Program Files(x86)\Java\jre7\bin\javaw.exe. So I placed my dlls including the tessdata folder in the same directory and deleted the dlls from System32. Still, the application crashes.
