Ubuntu环境配置

OpenCV

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

如果提示unable to locate libjasper-dev，可以执行以下代码：

sudo add-apt-repository "deb http://security.ubuntu.com/ubuntu xenial-security main"
sudo apt update
sudo apt install libjasper1 libjasper-dev  #libjasper1是libjasper-dev的依赖包

下载OpenCV和OpenCV-contrib模块

1. 官网地址
   OpenCV下载地址
2. git clone下载

cd <working_directory>
git clone https://github.com/opencv/opencv.git
git clone https://github.com/opencv/opencv_contrib.git

编译

1. 把opencv-contrib模块移入opencv目录下（没有contrib模块就不移入）

2. 在opencv目录下新建一个build目录

   cd <opencv_directory>
   mkdir build  //建立一个build目录，把cmake的文件都放着里边
   cd build　　　//进入build目录

3. 开始cmake，这一步需要一会儿才能cmake完。

   1. 有contrib模块

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

   2. 无contrib模块

      cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local ..

      编译过程中ippicv遇到下载问题，可以参考下面链接：https://blog.csdn.net/orDream/article/details/84311697

4. build一下，把代码编译成可执行文件

   make -j7 # 运行7个并行作业

5. 安装库文件

   sudo make install

PCL 1.9.1
