更新 apt-get（在安装前最好先更新一下系统，不然可能会安装失败。）
sudo apt-get update
sudo apt-get upgrade
安装依赖 （太多了，自己相应替换）
sudo apt -y install libopencv-dev build-essential cmake git libgtk2.0-dev pkg-config python-dev python-numpy
sudo apt -y install libdc1394-22 libdc1394-22-dev libjpeg-dev libpng12-dev libjasper-dev libavcodec-dev libavformat-dev
sudo apt -y install libswscale-dev libgstreamer0.10-dev libgstreamer-plugins-base0.10-dev libv4l-dev libtbb-dev libqt4-dev
sudo apt -y install libfaac-dev libmp3lame-dev libopencore-amrnb-dev libopencore-amrwb-dev libtheora-dev libvorbis-dev libxvidcore-dev x264 v4l-utils unzip
sudo apt -y install libopencv-dev build-essential cmake git libgtk2.0-dev pkg-config python-dev python-numpy libdc1394-22
sudo apt -y install libdc1394-22-dev libjpeg-dev libpng12-dev libjasper-dev libavcodec-dev libavformat-dev libswscale-dev
sudo apt -y install libgstreamer0.10-dev libgstreamer-plugins-base0.10-dev libv4l-dev libtbb-dev libqt4-dev libfaac-dev
sudo apt -y install libmp3lame-dev libopencore-amrnb-dev libopencore-amrwb-dev libtheora-dev libvorbis-dev libxvidcore-dev x264 v4l-utils unzip --fix-missing
下载并解包（手动下载快一些)
wget https://github.com/Itseez/opencv/archive/3.2.0.zip
unzip opencv-3.2.0.zip
编译
在cmake下载过程中可能会出现 ICV:DOWNLONDING ippicv_linux_20151201.tgz 但是一直下载不下来，自己可以手动下载，把压缩包放到opencv-3.2.0/3rdparty/ippicv/downloads/linux-808b791a6eac9ed78d32a7666804320e/下
cd opencv-3.2.0
mkdir build
cd build
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/home/your_path/opencv-3.2.0/lib -D WITH_TBB=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON -D WITH_QT=ON -D WITH_OPENGL=ON ..
安装
make -j8 (-j8是表示使用多线程编译，加快速度，make 过程比较漫长，请耐心等待)
使用安装命令，将opencv安装到系统目录下；若系统有多个opencv版本，可以不使用安装命令，在工程中使用的时候直接指定某个版本的opencv就好
sudo make install
安装完成，进行整理
sudo /bin/bash -c 'echo "/usr/local/lib" > /etc/ld.so.conf.d/opencv.conf'
sudo ldconfig
sudo apt-get update
测试是否安装成功
python
>>> import cv2
>>> cv2.__version__
'3.2.0'
>>>
