1.安装依赖

[compiler] sudo apt-get install build-essential
[required] sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev
[optional] sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev

2.下载opencv源码

navy@DEEPIN:~/Desktop$ mkdir workspace
navy@DEEPIN:~/Desktop$ cd workspace
git clone https://github.com/opencv/opencv.git
git clone https://github.com/opencv/opencv_contrib.git
git clone https://github.com/opencv/opencv_extra.git

3.使用cmake编译源码

navy@DEEPIN:~/Desktop/workspace$ mkdir build
navy@DEEPIN:~/Desktop/workspace$ cd build
navy@DEEPIN:~/Desktop/workspace/build$ cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local ../opencv
navy@DEEPIN:~/Desktop/workspace/build$ make -j7
navy@DEEPIN:~/Desktop/workspace/build$ sudo make install

4.其他根据需要安装

5.使用clion创建基于opencv的项目

6.修改CMakeLists.txt文件

7.源码编写

附源码

CMakeLists.txt文件

cmake_minimum_required(VERSION 3.9.5)
project(test)

set(CMAKE_CXX_STANDARD 14)
set(OpenCV_DIR "/home/navy/Desktop/workspace/build")
find_package(OpenCV REQUIRED)
include_directories(${OpenCV_INCLUDE_DIRS})
add_executable(test main.cpp)
set(OpenCV_LIBS opencv_core opencv_imgproc opencv_highgui opencv_imgcodecs)
target_link_libraries(test ${OpenCV_LIBS})

main.cpp文件

#include<opencv2/opencv.hpp>
#include <iostream>
#include <math.h>

using namespace cv;

int main(){
    Mat src = imread("/home/navy/Desktop/workspace/opencv_extra/testdata/gpu/caltech/image_00000009_0.png",0);
    if(src.empty()){
        printf("load fail\n");
    }
    namedWindow("test");
    imshow("test",src);
    waitKey(0);
    return 0;
}
