Ubuntu安装OpenCV

首先，我们需要安装一些必要的包

[compiler] sudo apt-get install build-essential
[required] sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev
[optional] sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev

然后，我们去官网下载Opencv2.4.13 for Linux

接着，我们进行编译和安装

unzip opencv-2.4.13.zip
cd opencv-2.4.13/
cmake -D WITH_GTK_2_X=ON -D CMAKE_INSTALL_PREFIX=/usr/local .
make    # make -j4表示开4个线程来进行编译
make install

安装完成后，我们查看下OpenCV版本进行测试

>>> import cv2
>>> cv2.__version__
'2.4.13'

出现版本信息，就是大功告成啦~
