Ubuntu 16.04安装opencv 2.4.13

1.下载安装一些一类包 以及编译工具

#安装编译工具
sudo apt-get install build-essential
#安装依赖包
sudo apt-get install cmake git libgtk2.0-dev pkg-config
libavcodec-dev libavformat-dev libswscale-dev
#安装可选包
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opencv

cd opencv-2.4.13
mkdir release   //新建一个文件夹用于存放临时文件
cd release

sudo cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local .. //开始编译(大概15分钟)
sudo make install

3.相关环境配置

sudo vim /etc/ld.so.conf.d/opencv.conf

sudo ldconfig （使配置生效）

ln -sf /usr/local/cuda-8.0/lib64/libcudnn.so.5.0.5 /usr/local/cuda-8.0/lib64/libcudnn.so.5

sudo ldconfig

sudo vim /etc/bash.bashrc

PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig export PKG_CONFIG_PATH

sudo source /etc/bash.bashrc #使配置生效

source /etc/bash.bashrc
ctrl+d (推迟root)
sudo updated（更新）

python
