代码下载：https://download.csdn.net/download/qq_40008325/11176459

https://sourceforge.net/projects/opencvlibrary/files/opencv-unix/3.3.0/

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

  1. 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：

  1. 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

  1. #include <opencv2/opencv.hpp> 
  3. int main()
  4. {    
  5.         cv::Mat image, image_gray;
  6.     image = cv::imread("1.png", cv::IMREAD_COLOR);
  7.     cv::imshow("lenna", image);
  8.     cv::cvtColor(image, image_gray, cv::COLOR_BGR2GRAY);
  9.     cv::imwrite("lenna_gray.jpg", image_gray);
  10.     cv::waitKey(0);
  11.     return 0;
  12. }

编译：

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