一、conda安装

如果你已经安装anaconda，那么接下来就简单了，直接如下命令安装。

conda install opencv

安装完成后进行测试。

python
import cv2

如果报错No module:cv2

pip install opencv-python

如果报错ImportError: libSM.so.6: cannot open shared object file: No such file or directory

apt-get update
apt-get install -y libsm6 libxext6 libxrender-dev

二、编译安装

Step 1: Update Packages

sudo apt -y update
sudo apt -y upgrade

Step 2: Download opencv and opencv_contrib

git clone https://github.com/opencv/opencv.git
cd opencv
git checkout $cvVersion
cd ..

git clone https://github.com/opencv/opencv_contrib.git
cd opencv_contrib
git checkout $cvVersion
cd ..

Step 3: Compile and install OpenCV with contrib modules

# First we navigate to the build directory
cd opencv
mkdir build
cd build


# Next, we start the compilation and installation process.

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 OPENCV_PYTHON3_INSTALL_PATH=/usr/lib/python3.5/site-packages \
        -D WITH_QT=ON \
        -D WITH_OPENGL=ON \
        -D OPENCV_EXTRA_MODULES_PATH=../../opencv_contrib/modules \
        -D BUILD_EXAMPLES=ON ..

make -j 4
make install

如果有报错，参考1中解决方法。其他报错，根据提示对症下药。
