openalpr编译步骤-vs2013
最近公司在搞车牌，偶然间发现国外一个比较好的车牌开源项目，于是决定移植过来学习学习。
本文最终实现openalpr在VS2013下的移植。参考网上很多资料，发现openalpr下还用到了很多其他的库，在此贴出我用的库。
giflib416-static-mtdll.lib
libjpeg8c-static-mtdll.lib
liblept171-static-mtdll.lib
libpng143-static-mtdll.lib
libtesseract304-static.lib
libtiff394-static-mtdll.lib
zlib128-static-mtdll.lib
这里贴出的是64位Release静态库，当然还有Debug版本，动态库的版本，32位的版本。
知道依赖库了，首先就是移植，编译这些依赖库。其中最重要的就是libtesseract304-static.lib
因为openalpr依赖于libtesseract304-static.lib，libtesseract304-static.lib再依赖于上面列出的其他库。
首先，我们移植libtesseract工程，项目主页为：https://github.com/tesseract-ocr/tesseract 因为我的是vs2013，所以参考的教程是https://vorba.ch/2014/tesseract-3.03-vs2013.html
下面一步一步贴出我移植的步骤：
1、安装环境，包括Git，SVN，OPENCV。并且需要更新这些执行文件到环境变量里面。
2、Building thedependencies
基本按照教程走，只是把目录换成我自己的了。
3、BuildingTesseract
这里需要注意的是，Tesseract代码已经不在Google管理了，所以SVN下载的时候要换成GitHub的地址。https://github.com/tesseract-ocr/tesseract
再按照教程走就能得到Tesseract的vs2013的工程了。这里注意vs中要配置属性中的opencv库。
4、按照这个教程，移植openalpr为vs2013的工程。

How to statically compiling, linking and using OpenALPR and Tesseract withVisual Studio 2013 on Windows?
All library is official I used. it consists of five parts:
Part 1: Downloading, installing and extracting tools.
Part 2: Building Tesseract OCR
Part 3: Reconfiguring OpenALPR with CMAKE for VS2013
Part 4: Building OpenALPR
Part 5: Using and testing OpenALPR
--------------------------------- PART 1 ----------------------------------
Let's download tools before
CMAKE WINDOWS INSTALLER: http://www.cmake.org/download/
OPENCV: http://sourceforge.net/projects/openc...
TESSERACT SOURCE CODES: https://tesseract-ocr.googlecode.com/...
TESSERACT INCLUDES: https://tesseract-ocr.googlecode.com/...
TESSERACT VS2008: https://tesseract-ocr.googlecode.com/...
LEPTONICA INCLUDES: https://leptonica.googlecode.com/file...
OPENALPR SOURCE CODES: https://github.com/openalpr/openalpr/...
I have already installed CMAKE
I have already downloaded TESSERACT
I have already downloaded LEPTONICA
I have already downloaded OPENALPR
I have already downloaded OPENCV
I extracted OpenCV 3.0 to "D:\GoruntuIsleme\OpenCV" directory
I will extract all codes to "C:\build" directory
PART 1 IS COMPLETE
注1：
CMAKE和OPENCV自己在網上下載就可以了。
TESSERACT和LEPTONICA庫就用上面編譯出來的庫。
-------------------------------- PART 2 ----------------------------------
I WILL BUİLD TESSERACT
Follow me now
I using libtesseract project
I changing project to "Release" mode
I adding INCLUDE DIRS to project
Finally I building project+
it is not important
Follow me for this message
rebuild
It was successfuly builded+
Now I moving .lib file to lib directory
PART 2 IS COMPLETE
注2：
此步驟就是將上面編譯出來的庫拷貝到openalpr源代碼的lib目錄下，并把頭文件放到include目錄下。
--------------------------------- PART 3 ----------------------------------
I WILL RECONFIGURE OPENALPR
I creating new folder for reconfigured codes for VS2013
I opening CMAKE
I adding path of openalpr source codes to CMAKE
I setting reconfigured source codes path
I setting CMAKE for Visual Studio 2013
I adding LEPTONICA and TESSERACT path
I adding OPENCV build path
I generating reconfigureed project+
Generating done
PART 3 IS COMPLETE
--------------------------------- PART 4 ----------------------------------
I WILL BUILD OPENALPR
I opening Reconfigured OpenALPR code: "src.sln"
I changing project to "Release" mode
I removing "openalpr" project from "Solution Explorer"because is dynamic library
I building "openalpr-static" project
Follow me for this error
I rebuilding now
it is done
I adding Tesseract lib directory to "AdditionalLibraryDirectories" on"alpr" project
I changing "Additional Dependencies"; openalpr.lib toopenalpr-static.lib
I adding following lines to "Additional Dependencies"
libtesseract302-static.lib
liblept168-static-mtdll.lib
libtiff394-static-mtdll.lib
libjpeg8c-static-mtdll.lib
libpng143-static-mtdll.lib
giflib416-static-mtdll.lib
I changing "Image Has Safe Exception Handlers" to NO
I adding same settings to "unittest" project.
I building...
It was successfully builded
aplr.exe and unittest.exe in here
PART 4 IS COMPLATE
注3：
附加庫的名稱要用剛才添加到lib目錄下的名稱，不然會存在找不到庫的問題。
--------------------------------- PART 5 ----------------------------------
I WILL TEST OPENALPR WITH A CAR IMAGE
At first, This folder not important, is empty, you can delete it
I adding OPENCV bin dir to PC Environment
I copying runtime_data folder to Release folder
I copying openalpr.conf to Release folder
I copying image file to Release folder
I opening CMD
cd into Release
And running alpr.exe with this:
alpr dd.jpg -c eu
ALL DONE
THANKS FOR WATCHING
Mr. Kozmon
