Opencv在mac系统的安装与试用

1.在mac终端内，使用brew安装opencv3，这时我的opencv被安装到/usr/local/Cellar/opencv3/3.2.0内。

2.新建xcode 项目，选择command line tool，在项目目录内新建一个group，把/usr/local/Cellar/opencv3/3.2.0/lib内的含有libopencv的dylib都添加进去。

3.在build settings 内更改Header Search Paths为/usr/local/Cellar/opencv3/3.2.0/include, Library Search Paths 更为/usr/local/Cellar/opencv3/3.2.0/lib。注意此处不能copy网上仅仅是/usr/local/include 或者/usr/local/lib，要根据你opencv安装地址而定

4.在main函数中输入，即可显示出图片，注意图片的路径要正确，自己定。

#include "opencv2/core.hpp"

#include "opencv2/imgcodecs.hpp"

#include "opencv2/highgui.hpp"

#include <iostream>

#include <string>

using namespace cv;

using namespace std;

int main(int argc, char** argv)

{

    String imageName("/Users/mac-jcc/Desktop/opencv-00/jcc.png");

    Mat image;

    image = imread(imageName, IMREAD_COLOR);

    if(image.empty())

    {

        cout<<"could not open or find the image"<<std::endl;

        return -1;

    }

    namedWindow( "Display window", WINDOW_AUTOSIZE ); 

    imshow( "Display window"，image );                

    waitKey(0);

    return 0;

}
