sudo apt-get install p7zip

解压缩7z文件

7za x opencv3.3安装包.7z -r -o./

解压后的文件是opencv3.3

安装记录：

cd opencv3.3

mkdir build

cd build

使用CMake   
cmake -D CMAKE\_BUILD\_TYPE=RELEASE \\  
      -D CMAKE\_INSTALL\_PREFIX=/usr/local \\  
      -D INSTALL\_C\_EXAMPLES=ON \\  
      -D INSTALL\_PYTHON\_EXAMPLES=ON \\  
      -D WITH\_TBB=ON \\  
      -D WITH\_V4L=ON \\  
      -D WITH\_QT=ON \\  
      -D WITH\_OPENGL=ON \\  
      -D OPENCV\_EXTRA\_MODULES\_PATH=/usr/local \\  
      -D BUILD\_EXAMPLES=ON ..

sudo make -j8

sudo make install

sudo sh -c 'echo "/usr/local/lib" >> /etc/ld.so.conf.d/opencv.conf'

sudo ldconfig

方法二：

接下来就需要配置一些OpenCV的编译环境首先将OpenCV的库添加到路径

sudo gedit /etc/ld.so.conf.d/opencv.conf

里面添加：添加后保存

sudo ldconfig

opencv安装测试：

pkg-config --cflags --libs opencv

下载补充：linux下命令行下载（3.4可以正常安装)

wget https://sourceforge.net/projects/opencvlibrary/files/opencv-unix/3.4.3/opencv-3.4.3.zip

unzip opencv-3.4.3.zip

cd opencv-3.4.3

mkdir build && cd build

cmake -D CMAKE\_BUILD\_TYPE=RELEASE -D CMAKE\_INSTALL\_PREFIX=/usr/local ..

sudo make && sudo make install

测试opencv

#include <opencv2/opencv.hpp> 
    
    int main()
    {	
            cv::Mat image, image_gray;
    	image = cv::imread("1.png", cv::IMREAD_COLOR);
    	cv::imshow("lenna", image);
    	cv::cvtColor(image, image_gray, cv::COLOR_BGR2GRAY);
    	cv::imwrite("lenna_gray.jpg", image_gray);
    	cv::waitKey(0);
    	return 0;
    }

编译：

g++ `pkg-config opencv --cflags` 1.cpp  -o app `pkg-config opencv --libs`
