[mcj]Ubuntu16.04安装OpenCV3.4.5详细教程

其实不止适用于Ubuntu16.04，同样适用于Ubuntu14.04，以及安装opencv3.4.5以下版本！

1 开发环境：

Ubuntu 16.04 64位
cmake
ant
jdk
git
python

2 下载安装包

从github中down下OpenCV + OpenCV_Contrib库，可以从https://github.com/opencv上下载（注意版本对应），也可以通过指令下载（建议使用）：

git clone https://github.com/Itseez/opencv.git
git clone https://github.com/Itseez/opencv_contrib.git

这种下载方法一般是下载的最新版，我们想要下载3.4.5版本的，可以到github上下载指定版本的压缩包。下载过程中，我们可以先安装依赖。

3 安装依赖

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

卸载apt安装的opencv：

sudo apt-get autoremove libopencv-dev

4 编译

将下载好的压缩包解压，将contrib放入opencv目录下，并命名opencv_contrib，接着创建文件夹build，最后opencv目录结构如下：

进入build文件夹，然后打开终端，输入：

cmake -D CMAKE_INSTALL_PREFIX=/usr/local -D CMAKE_BUILD_TYPE=Release -D OPENCV_EXTRA_MODULES_PATH=../opencv_contrib/modules ..

注意后面两个点不要忘了输。

这时开始编译，等待一段时间（大概10分钟以内吧），出现以下结果：

然后，就可以make了：

make -j8

这个时间也比较长，大概五分钟左右吧，安装完毕：

到了这一步等于已经安装成功了。接下来只需要将编译好的文件安装到系统目录即可。
