升级到新版本
尝试执行cmake,提示我们需要安装3.2版本openCV

CMake Error at CMakeLists.txt:13 (find_package):
Could not find a configuration file for package "OpenCV" that is compatible
with requested version "3.2.0".
The following configuration files were considered but not accepted:
/usr/local/share/OpenCV/OpenCVConfig.cmake, version: 2.4.13.2
-- Configuring incomplete, errors occurred!
See also "/Users/tyrad/Desktop/EsayPR/CMakeFiles/CMakeOutput.log".
尝试安装opencv3
brew install opencv3
Error: opencv 2.4.13.2 is already installed
To upgrade to 3.3.0_3, run `brew upgrade opencv`
继续按提示安装:
查看当前的版本:
pkg-config --modversion opencv
安装

cmake
~ cmake -version
cmake version 3.9.0
1). 修改 include/esaypr/config.h 文件
Opencv3.2版本的支持，编译前仅需要将config.h中将#define CV_VERSION_THREE_ZERO改为#define CV_VERSION_THREE_TWO即可。
config.h文件的位置：include/esaypr/config.h
2). 为了避免系统中安装的老版本opencv对编译的影响，需要在 CMakeLists.txt 中修改：
set(CMAKE_PREFIX_PATH ${CMAKE_PREFIX_PATH} "/usr/local/opt/opencv@3")
3). 项目提供了一键编译shell，
最后在目录生成了demo文件,尝试下运行:
./demo recognize -p resources/image/plate_recognize.jpg --svm resources/model/svm.xml --ann resources/model/ann.xml
具体使用: https://github.com/liuruoze/EasyPR/blob/master/Usage.md
1). 集成openCV具体看这里
2). 将libeasypr.a、libthirdparty.a、include目录导入工程
3). header search path添加: $(SRCROOT)/EasyPRDemo/include
4). Edit Scheme中,将Work Directory改成当前工程的路径
5). 将EasyPR原文件中的models目录放到当前当前工程目录下(目的是为了和include/easypr/config.h中的路径对应起来)
6). 测试效果
#include <iostream>
#include <opencv2/opencv.hpp>
#include "easypr.h"
using namespace easypr;
using namespace cv;
void showImage2();
int main(int argc, const char * argv[]) {
// insert code here...
std::cout << "Hello, World!\n";
CPlateRecognize pr;
pr.setResultShow(false);
pr.setDetectType(PR_DETECT_CMSER);
vector<CPlate> plateVec;
Mat src = imread("test.jpg");
int result = pr.plateRecognize(src, plateVec);
if(plateVec.size() > 0){
string name=plateVec[0].getPlateStr();
cout<<endl<<"resunt = "<<name <<endl;
}
return 0;
}
使用 Xcode cmake
测试环境 Xcode9.0
1). 进入下载好的EasyPR目录下
2). 创建新目录Xcode: mkdir Xcode
3). cd Xcode
4). cmake -G "Xcode" ..
5).需要配置的地方:
Edit Scheme中,将Work Directory改成EasyPR所在路径。
6). 运行Demo target 即可
