opencv-3.2.0安装
安装依赖
sudo apt-get install build-essential
sudo apt-get install libgtk2.0-dev libavcodec-dev libavformat-dev libtiff4-dev libswscale-dev libjasper-dev
sudo apt-get install cmake
sudo apt-get install pkg-config
opencv-3.2.0下载配置
sudo wget https://codeload.github.com/opencv/opencv/zip/3.2.0
解压：sudo unzip 3.2.0.zip
进入目录：cd opencv-3.2.0
创建安装目录：sudo mkdir build
在根目录设置编译参数：cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/home/pi/opencv/opencv-3.2.0/build -DENABLE_PRECOMPILED_HEADERS=OFF
编译安装
编译：sudo make
安装：sudo make install
最后配置
/etc/ld.so.conf.d 目录下增加一个conf文件（可以命名为 opencv3.2.0.conf），同样添加安装目录 /home/pi/opencv/opencv-3.2.0/build
动态库管理命令ldconfig，让opencv的相关链接库被系统共享：sudo ldconfig -v
为程序指定openvc的头文件位置。这里使用pkg-config命令来完成。首先在 /etc/profile 中添加:export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/home/pi/opencv/opencv-3.2.0/build/lib/pkgconfig
pkg-config 命令可以列出关于opencv的配置信息:pkg-config --libs opencv
EasyPR安装
EasyPR下载
git clone https://github.com/liuruoze/EasyPR.git
进入目录：cd EasyPR
安装配置
配置文件：vim CMakeLists.txt ，修改下面：
# OpenVC3 required set(CMAKE_PREFIX_PATH ${CMAKE_PREFIX_PATH} "/home/pi/opencv/opencv-3.2.0/build/share/OpenCV") find_package(OpenCV 3.2.0 REQUIRED)
修改头文件EasyPR/include/easypr/config.h，#define CV_VERSION_THREE_ZERO改为#define CV_VERSION_THREE_TWO
编译安装
首先进入目录EasyPR
删除目录：sudo rm -rf build
创建目录：sudo mkdir build
进入目录：cd build
执行命令：sudo cmake ..
编译：sudo make
返回上层目录：cd ..
执行测试demo：./demo recognize -p resources/image/plate_recognize.jpg --svm resources/model/svm.xml
