環境 : Android 4.2 + leptonica-1.71.tar.gz
- Android 版 tesseract
必備 : leptonica
( compile方法參考README ) - tesseract - 語言包
( 語言包下載後,路徑如 : /mnt/sdcard/tesseract/tessdata/eng.traineddata) - 建立一個專案,接者把compile好的jar檔加入專案:
專案上右鍵 > Properties > Android > 下方的Library加入 tess-two和eyes-two

Google Glass OCR Tutorial using Eclipse
請問我參考你的文章且我也照著下列的方法去做,但是用手機執行後,拍攝完進入ocr的時候就停止了 想請問這個問題可能是卡在哪裡呢??
回覆刪除Download the NDK from the Android Development site and extract it to any folder.
Go to Preferences-->Android -->NDK and select the path for Android-Ndk directory ex-->D:\Work\Android\Android Tools\android-ndk-r9
Import tess-two project. File -> Import -> Existing Projects into workspace -> tess-two directory.
Right Click on Tess-two--> Properties-->Builders then give any name for Builder like Ndk tess Builder And add location for ndk-build.cmd ex-->:D:\Work\Android\Android Tools\android-ndk-r9\ndk-build.cmd. select working directory as ${Workspace/tess-two}
Refresh tess-two, It will take time to build
After complete build Add it as library:Right click the project, Android Tools -> Fix Project Properties. Right click -> Properties -> Android -> Check Is Library.
嗨,你好
回覆刪除我是用linux環境去compile的, 然後也是在linux下使用eclipse完成的
使用過程都沒問題 : )
