1、安装依赖
命令：sudo apt-get install build-essential
命令：sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev
命令：sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev
2、下载源码
网址：https://download.csdn.net/download/u011109761/10558274
3、下载之后解压opencv_file.tar.gz
命令：tar -zxvf opencv_file.tar.gz
命令：cd opencv_file/opencv
命令：mkdir build
命令：cd build
命令：cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local -D OPENCV_EXTRA_MODULES_PATH=<path to opencv_contrib/modules/> ..
提示：<path to opencv_contrib/modules/>改为自己的路径，注：命令中最后的" .. "（空格+两个点）千万不要忘记
命令：make -j7 # 并行运行七个jobs，这一步也在build目录中进行
命令：sudo make install #这一步也在build目录中进行
提示：以上安装完毕
4、测试安装是否成功
命令：cd opencv_file/opencv/samples/python
命令：python asift.py
5、结果
