Mac下安装 OpenCV

Mac下安装 OpenCV

1.下载Opencv：

cd ~/<my_working _directory>
svn co http://code.opencv.org/svn/opencv/trunk

2.使用CMake编译Opencv

cd ~/opencv
mkdir release
cd release
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local ..
make
sudo make install

3.测试～
cpp 代码：

#include <cv.h>
#include <highgui.h>

using namespace cv;

int main(int argc, char** argv) {
    Mat image;
    image = imread(argv[1], 1);

    if(argc != 2 || !image.data) {
        printf("No image data \n");
        return -1;
    }

    namedWindow("Display Image", CV_WINDOW_AUTOSIZE);

    imshow("Display Image", image);

    waitKey(0);

    return 0;
}

Cmake 代码：

project( DisplayImage )
find_package( OpenCV REQUIRED )
add_executable( DisplayImage DisplayImage )
target_link_libraries( DisplayImage ${OpenCV_LIBS} )

终端运行：
