Raspbian安装Opencv3

如果旧版本使用apt-get安装
sudo apt-get remove libopencv
sudo apt-get remove opencv
 
如果旧版本使用编译安装
sudo make uninstall

2. 安装相关依赖

sudo apt-get install build-essential
sudo apt-get install cmake git libgtk2.-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev
 
sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394--dev

3. 下载opencv到任意目录下

git clone https://github.com/Itseez/opencv.git
git clone https://github.com/Itseez/opencv_contrib.git
cd opencv

  git checkout 3.1.0

  cd ..

  git checkout 3.1.0

  cd ..

4. 编译

cd opencv
mkdir release
cd release
 
cmake -D CMAKE_BUILD_TYPE=RELEASE \
    -D CMAKE_INSTALL_PREFIX=/usr/local \
    -D INSTALL_PYTHON_EXAMPLES=ON \
    -D OPENCV_EXTRA_MODULES_PATH=~/opencv_contrib/modules \
    -D BUILD_EXAMPLES=ON ..
 
注意修改OPENCV_EXTRA_MODULES_PATH的目录为您本机中opencv_contrib的目录，否则会报configuring incomplete

5. 安装

make -j4
sudo make install
sudo ldconfig

6. 测试

python
 
>>import cv2
>>cv2.__version__
