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 ~/opencvmkdir releasecd releasecmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local ..?makesudo 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：
