Android OCR using tess-two a fork of tesseract
提问by Alfred
Am using OCR as a module in a project that am doing. After digging in deep for a week i thought that i should run a test application on eclipse just to see how accurately it works. i found tess-two a fork of tesseract as a support to my OCR. i downloaded tess-two from:
我在正在做的项目中使用 OCR 作为模块。在深入研究一周后，我认为我应该在 eclipse 上运行一个测试应用程序，看看它的工作准确度如何。我发现 tess-two 是 tesseract 的一个分支，作为对我的 OCR 的支持。我从以下位置下载了 tess-2：
https://github.com/rmtheis/tess-two/downloads
https://github.com/rmtheis/tess-two/downloads
I was all set i imported tess-two into my eclipse. I did set my eclipse for handling and building projects involving native code. I did build tess-two successfully after solving 1 or 2 build path errors. DONE!
我已经准备好将 tess-two 导入到我的日食中。我确实设置了我的 Eclipse 来处理和构建涉及本机代码的项目。在解决 1 或 2 个构建路径错误后，我确实成功构建了 tess-2。完毕！
Then i found a simple OCR application which was using the same tess-two. i download it from:
然后我发现了一个简单的 OCR 应用程序，它使用相同的 tess-two。我从以下地址下载：
https://github.com/GautamGupta/Simple-Android-OCR
https://github.com/GautamGupta/Simple-Android-OCR
I imported this project into my workspace. Corrected the build path i included tess-two as a supporting project in the build path. When i successfully build the two projects and run it on my target device the application runs successfully. when i run the camera with the button the camera opens but when i save the picture so that the ocr runs on it i get an exception:
我将这个项目导入到我的工作区。更正了我在构建路径中包含 tess-two 作为支持项目的构建路径。当我成功构建这两个项目并在我的目标设备上运行它时，应用程序成功运行。当我使用按钮运行相机时，相机会打开，但是当我保存图片以便在其上运行 ocr 时，出现异常：
could not find class 'com.googlecode.tesseract.android.TessBaseAPI' referenced from method com.datumdroid.android.ocr.simple.SimpleAndroidOCRActicity.picturetaken'
This was the exception generated by the logcat on eclipse. Any idea how can i deal and remove this exception?? Tess-two was android target-8 and simple ocr application was target-10.
这是eclipse上logcat产生的异常。知道如何处理和删除此异常吗？Tess-2 是 android target-8，简单的 ocr 应用程序是 target-10。

make sure you marked tess-two as a library in the properties then right click your simple ocr and in the properties add tess two library and apply
确保您在属性中将 tess-two 标记为库，然后右键单击您的简单 ocr 并在属性中添加 tess 两个库并应用
