Ubuntu 16.04 LTS 安装OpenCV3.2

实不相瞒，折腾opencv真是要了我电脑的老命，google了一大圈终于找到了一个省事的方法，就是使用github上的脚本，简直一键安装啊，真是感谢作者啊，我这里放出原链接吧OpenCV3.2一键安装脚本。

如果大家不想麻烦的的话我把它复制过来了，还把里面的apt-get换成了apt，这个其实没什么大区别，就是多了个进度条，官方推荐使用apt来代替apt-get，我的这个需要大家提前安装好Java环境。

使用的话就是新建一个install.sh文件，把下面的这些复制进去，保存，加执行权限chmod u+x install.sh，再sudo ./install.sh就可以自动安装了，这个是从源码安装的所以时间可能会比较长。

# 1. KEEP UBUNTU OR DEBIAN UP TO DATE

sudo apt -y update
sudo apt -y upgrade
sudo apt -y dist-upgrade
sudo apt -y autoremove

# 2. INSTALL THE DEPENDENCIES

# Build tools:
sudo apt install -y build-essential cmake

# GUI (if you want to use GTK instead of Qt, replace 'qt5-default' with 'libgtkglext1-dev' and remove '-DWITH_QT=ON' option in CMake):
sudo apt install -y qt5-default libvtk6-dev

# Media I/O:
sudo apt install -y zlib1g-dev libjpeg-dev libwebp-dev libpng-dev libtiff5-dev libjasper-dev libopenexr-dev libgdal-dev

# Video I/O:
sudo apt install -y libdc1394-22-dev libavcodec-dev libavformat-dev libswscale-dev libtheora-dev libvorbis-dev libxvidcore-dev libx264-dev yasm libopencore-amrnb-dev libopencore-amrwb-dev libv4l-dev libxine2-dev

# Parallelism and linear algebra libraries:
sudo apt install -y libtbb-dev libeigen3-dev

# Python:
sudo apt install -y python-dev python-tk python-numpy python3-dev python3-tk python3-numpy

# Java:
# 我的就这里和原来的不太一样，因为我的电脑原来安装了Java的环境了
# sudo apt install -y ant default-jdk
# Documentation:
sudo apt install -y doxygen

# 3. INSTALL THE LIBRARY (YOU CAN CHANGE '3.2.0' FOR THE LAST STABLE VERSION)

sudo apt install -y unzip wget
wget https://github.com/opencv/opencv/archive/3.2.0.zip unzip 3.2.0.zip
rm 3.2.0.zip
mv opencv-3.2.0 OpenCV
cd OpenCV
mkdir build
cd build
cmake -DWITH_QT=ON -DWITH_OPENGL=ON -DFORCE_VTK=ON -DWITH_TBB=ON -DWITH_GDAL=ON -DWITH_XINE=ON -DBUILD_EXAMPLES=ON -DENABLE_PRECOMPILED_HEADERS=OFF ..
make -j4
sudo make install
sudo ldconfig

# 4. EXECUTE SOME OPENCV EXAMPLES AND COMPILE A DEMONSTRATION
