1.环境检查
需安装：
gcc
cmake
2.下载下载opencv的安装包opencv-3.1.0.zip
wget http://nchc.dl.sourceforge.net/project/opencvlibrary/opencv-unix/3.1.0/opencv-3.1.0.zip
3.将安装包移动到指定安装路径并解压
mv opencv-3.1.0.zip /usr/local
unzip opencv-3.1.0.zip
4.编译
cd /usr/loacal/opencv-3.1.0
camke CMakeList.txt
如果这里出错，显示808b791a6eac9ed78d32a7666804320e的hash dismatch
可以自己先在网上下载好ippicv_linux_20151201.tgz这个压缩包，然后将其拷贝到下面的文件夹目录：
/usr/local/opencv-3.1.0/3rdparty/ippicv/downloads/linux-808b791a6eac9ed78d32a7666804320e/
然后重新cmake CMakeList.txt
5.编译安装
cd /usr/local/opencv-3.1.0
make
如下所示为编译成功
执行
make install
即可
