简介

OpenCV是一个基于BSD许可（ 开源 ）发行的跨平台计算机视觉库，可以运行在Linux、Windows、Android和Mac OS操作系统上。它轻量级而且高效——由一系列C函数和少量C++类构成，同时提供了Python、Ruby、MATLAB等语言的接口，实现了图像处理和计算机视觉方面的很多通用算法。

编译和测试方式

1.配置编译环境

1)安装wget工具。

yum install wget -y

2)安装OpenCV依赖库和工具

yum install -y git gcc-c++  -y

3)安装cmake依赖

yum install -y git gcc-c++ cmake
----结束

2.获取源码

获取“OpenCV-3.0.0”源码包。

cd /usr/local/src
wget https://github.com/opencv/opencv/archive/3.0.0.tar.gz

3.编译和安装

编译“OpenCV-3.0.0”并进行安装。

cd /usr/local/src/
tar -zxvf 3.0.0.tar.gz
cd opencv-3.0.0/
mkdir build
cd build/
cmake ..
make -j8 && make instal

4.运行和验证

查看安装OpenCV所生成的库文件和头文件。

ll /usr/local/lib

回显内容如下，表示安装正常。
