1.更新系统
sudo apt-get update sudo apt-get upgrade
2.安装编译工具和依赖包
sudo apt-get install build-essential sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev
3.下载opencv并解压
网址：https://opencv.org/releases.html
mkdir opencv cd opencv
unzip 3.2.0.zip
4.编译安装OpenCV
mkdir build cd build cmake .. #默认设置 make -j7# 多线程执行make任务 sudo make install
5.添加OpenCV库添加到路径（没有opencv.conf文件会自动创建）
sudo gedit /etc/ld.so.conf.d/opencv.conf
6.在文件中添加
/usr/local/lib
执行如下命令使配置路径生效
sudo ldconfig
7.配置bash
sudo gedit /etc/bash.bashrc
在最末尾添加
PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig
export PKG_CONFIG_PATH
保存，执行如下命令使得配置生效
source /etc/bash.bashrc sudo updatedb
8.测试opencv
找到~/opencv-3.2.0/samples/cpp/example_cmake目录
mkdir build cd build cmake .. make ./opencv_example
至此完成配置
