ubuntu16.04 完整make安装opencv 3.2.0

ubuntu下卸载opencv步骤

1. 进入build文件夹，命令行执行make uninstall

2. cd ..

3. sudo rm -r build

4. sudo rm -r /usr/local/include/opencv2 /usr/local/include/opencv /usr/include/opencv /usr/include/opencv2 /usr/local/share/opencv /usr/local/share/OpenCV /usr/share/opencv /usr/share/OpenCV /usr/local/bin/opencv* /usr/local/lib/libopencv*

 

 

安装相关依赖库（相关依赖库一定得装上，否则后果自负）

sudo apt-get update

sudo apt-get upgrade

sudo apt-get install build-essential cmake pkg-config

sudo apt-get install libjpeg8-dev libtiff5-dev libjasper-dev libpng12-dev

sudo apt-get install libavcodec-dev libavformat-dev libswscale-dev libv4l-dev

sudo apt-get install libxvidcore-dev libx264-dev

sudo apt-get install libgtk-3-dev

sudo apt-get install libatlas-base-dev gfortran

sudo apt-get install python3.5-dev

 

 

执行cmake命令

cmake -D CMAKE_BUILD_TYPE=RELEASE  -D CMAKE_INSTALL_PREFIX=/usr/local -D PYTHON3_EXECUTABLE=/usr/bin/python3 -D PYTHON3_INCLUDE_DIR=/usr/include/python3.5 -D PYTHON3_LIBRARY=/usr/lib/x86_64-linux-gnu/libpython3.5m.so -D PYTHON3_NUMPY_INCLUDE_DIRS=/usr/local/lib/python3.5/dist-packages/numpy/core/include -D WITH_FFMPEG=ON -D WITH_TBB=ON -D WITH_GTK=ON -D WITH_LIBV4L=ON ..

 

执行编译命令

make -j8

 

执行安装命令

sudo make install

 

加入到动态链接库

sudo ldconfig

 

 

查看是否支持FFMPEG

python -c "import cv2; print(cv2.getBuildInformation())" | grep -i ffmpeg

输出FFMPEG: YES才是正确的

 

 

查看opencv版本

pkg-config --modversion opencv
