安装OpenCV
OpenCV 官网，下载见 SourceForge and GitHub。
若使用官网版本安装不成功，则可试试Github版本。
或者
git clone https://github.com/Itseez/opencv.git安装依赖库

wget https://codeload.github.com/opencv/opencv/zip/3.2.0
unzip 3.2.0 && cd opencv-3.2.0
mkdir build
cd build 或者 推荐下面的下载方法。
git clone https://github.com/Itseez/opencv.git
cd opencv编译安装

import cv2配置Python3.5 调用OpenCV
以上OpenCV的python解释器版本是2.7, Python3.5想调用OpenCV，如何配置呢
安装依赖库
sudo apt-get update
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-setuptools python3-dev sudo easy_install3 pip
pip3 install numpy
sudo apt-get install cmake git libgtk2.0-dev 特别注意
sudo apt install python3-dev libpython3.5-dev python3-numpy1. 进入opencv-3.2.0/build/路径下，执行ccmake
sudo ccmake .2. 添加python3路径
向下翻页，找到python3，手动添加自己的python3路径 
具体添加细节如下
CMAKE_BUILD_TYPE=Release
CMAKE_INSTALL_PREFIX=/usr/local
PYTHON3_EXECUTABLE=/usr/bin/python3
PYTHON3_INCLUDE_DIR=/usr/include/python3.5
PYTHON3_LIBRARY=/usr/lib/x86_64-linux-gnu/libpython3.5m.so
PYTHON3_NUMPY_INCLUDE_DIRS=/usr/local/lib/python3.5/dist-packages/numpy/core/include命令行配置方法
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 ..3. 生成make文件
按c键配置。如果有错，例如找不到xx库，自行调整对应选项或者安装对应库。配置成功后，按g键生成makefile。
4. make一下
make一下。多核处理器优势很大，几分钟就make好了。
sudo make -j12 # 根据你自己电脑核心数
sudo make install 5. 验证
python3
import cv26.查询OpenCV版本
pkg-config --modversion opencv 或者
python
import cv2
cv2.__version__参考文献
