OpenCV C++ (for Mac)

OpenCV的项目构建使用的是CMake.

简单的实现一个Demo 来实现在Mac上的C++测试，效果如下：

在Mac上使用HomeBrew安装：

brew install opencv

安装成功后，简单测试一下使用、

CMakeLists.txt

#设置版本号

cmake_minimum_required(VERSION 3.5)

project(OpenCV_Test)

set(CMAKE_CXX_STANDARD 11)

find_package(OpenCV REQUIRED)

include_directories(${OpenCV_INCLUDE_DIRS})

set(CMAKE_CXX_STANDARD 11)

add_executable(OpenCV_Test main.cpp)

target_link_libraries(OpenCV_Test ${OpenCV_LIBS})

main.cpp:

#include

#include

#include<string>

using namespace cv;

voidImageThreshold(std::string str) {

    Mat image = imread(str);

    imshow("test_opencv",image);

    waitKey(0);

}

int main() {

    std::string str ="/Users/huangshiping/Desktop/aaa.png";

    ImageThreshold(str);

    return0;

}

在当前目录下执行： 

cmake .

make 

./OpenCV_Test
