Linux搭建OpenCV环境

1. sudo apt-get install build-essential


2. sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev


3. sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev


4. git clone https://github.com/opencv/opencv.git


5. 使用CMake编译OpenCV源代码：
   
   
   
   1. 创建一个临时文件夹，用来存放生成的makefiles。Create a temporary directory, which we denote as <cmake_binary_dir>, where you want to put the generated Makefiles, project files as well the object files and output binaries.
   
   
   2. 进入这个临时文件夹：cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local <opencv源代码路径>
   
   
   
   


6. 在这个临时文件夹下运行make -j8 # -j8 runs 8 jobs in parallel. Change 8 to number of hardware threads available.


7. 运行：sudo make install
