    一、更新源

    1
    2
    mv sources.list /etc/apt/sources.list 
    mv raspi.list /etc/apt/sources.list.d/raspi.list

    更新源的配置，注意文件存放的位置
    文件sources.list和raspi.list具体内容如下

    sources.list文件: 

    deb http://mirrors.ustc.edu.cn/raspbian/raspbian/ stretch main contrib non-free rpi
deb http://mirrors.aliyun.com/raspbian/raspbian/ stretch main contrib non-free rpi
deb http://mirrors.tuna.tsinghua.edu.cn/raspbian/raspbian/ stretch main contrib non-free rpi
deb http://mirrors.neusoft.edu.cn/raspbian/raspbian/ stretch main contrib non-free rpi

    raspi.list文件:

    deb http://mirrors.ustc.edu.cn/raspbian/raspbian/ stretch main ui
    deb http://mirrors.aliyun.com/raspbian/raspbian/ stretch main ui
    deb http://mirrors.tuna.tsinghua.edu.cn/raspbian/raspbian/ stretch main ui
    deb http://mirrors.neusoft.edu.cn/raspbian/raspbian/ stretch main ui

    在终端执行更新命令:

    1
    2
    sudo apt-get update
    sudo apt-get upgrade

    二、安装依赖包

    sudo apt-get install build-essential cmake git pkg-config 
    sudo apt-get install libjpeg8-dev 
    sudo apt-get install libtiff5-dev 
    sudo apt-get install  libjasper-dev 
    sudo apt-get install  libpng12-dev

    sudo apt-get install libavcodec-dev libavformat-dev libswscale-dev libv4l-dev
    sudo apt-get install libgtk2.0-dev
    sudo apt-get install libatlas-base-dev gfortran

    注意：降级安装
    有些安装包依赖的版本低需要降级安装，如下，对depends后面的进行降级安装

    1
    sudo aptitude install xxxx

    三、下载源码

    1
    git clone https://github.com/opencv/opencv.git

    四、编译

    1

    4
    cmake dir/of/opencv/source
    sudo make -j4 
    sudo make install
    sudo ldconfig
