安装OPenCV

https://blog.csdn.net/u014337397/article/details/80895940

CLion配置opencv

cmake_minimum_required(VERSION 3.8)
project(helloCV)

include_directories(/usr/local/include/opencv4/opencv2)
set (OpenCV_LIBS /usr/local/lib)
find_package(OpenCV REQUIRED)


set(CMAKE_CXX_STANDARD 11)
set(SOURCE_FILES main.cpp)
add_executable(helloCV ${SOURCE_FILES})

target_link_libraries(helloCV ${OpenCV_LIBS})

• 增加内容为 :

include_directories(/usr/local/include/opencv4/opencv2)
set (OpenCV_LIBS /usr/local/lib)
find_package(OpenCV REQUIRED)
target_link_libraries(helloCV ${OpenCV_LIBS})

跑helloworld代码

#include <opencv2/opencv.hpp>
#include <iostream>
#include <string>
using namespace cv;
using namespace std;
int main(int argc,char **argv)
{
    Mat img = imread("../test.jpg");
    cout<<img;
    if(img.empty())
    {
        cout<<"error";
        return -1;
    }
    cout<<"My picture: "<< img.size() <<endl;
    imshow("image",img);
    waitKey();
    return 0;
}
