$ sudo apt-get update $ sudo apt-get upgrade # 开发工具 $ sudo apt-get install build-essential cmake unzip pkg-config # 图形库 $ sudo apt-get install libjpeg-dev libpng-dev libtiff-dev # 视频库 $ sudo apt-get install libjpeg-dev libpng-dev libtiff-dev $ sudo apt-get install libxvidcore-dev libx264-dev # GTK $ sudo apt-get install libgtk-3-dev # 其他 $ sudo apt-get install libatlas-base-dev gfortran # python头文件 $ sudo apt-get install python3-dev

下载

$ cd ~ $ wget -O opencv.zip https://github.com/opencv/opencv/archive/3.4.1.zip $ wget -O opencv_contrib.zip https://github.com/opencv/opencv_contrib/archive/3.4.1.zip $ unzip opencv.zip $ unzip opencv_contrib.zip

官方安装文档

上图的右上角的"OpenCV"旁边可以看到最新的版本号。如果你要使用opencv3.4.3，修改https://github.com/opencv/opencv/archive/3.4.1.zip 为https://github.com/opencv/opencv/archive/3.4.3.zip 即可。

安装

$ mkdir build $ cd build $ cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr/local -DOPENCV_EXTRA_MODULES_PATH=../../opencv_contrib-3.4.0/modules -DOPENCV_ENABLE_NONFREE=True $ sudo make install $ export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH $ sudo ldconfig
