Ubuntu16.04安装PCL并测试

第一步、 安装依赖

     sudo apt-get update
     sudo apt-get install git build-essential linux-libc-dev
     sudo apt-get install cmake cmake-gui 
     sudo apt-get install libusb-1.0-0-dev libusb-dev libudev-dev
     sudo apt-get install mpi-default-dev openmpi-bin openmpi-common  
     sudo apt-get install libflann1.8 libflann-dev
     sudo apt-get install libeigen3-dev
     sudo apt-get install libboost-all-dev
     sudo apt-get install libvtk5.10-qt4 libvtk5.10 libvtk5-dev
     sudo apt-get install libqhull* libgtest-dev
     sudo apt-get install freeglut3-dev pkg-config
     sudo apt-get install libxmu-dev libxi-dev 
     sudo apt-get install mono-complete
     sudo apt-get install qt-sdk openjdk-8-jdk openjdk-8-jre

第二步、下载源码

git clone https://github.com/PointCloudLibrary/pcl.git

这一步我在ubuntu系统下载很慢，直接用windows系统下载好，然后粘贴到对应位置上。

第三步、 编译源码
（这一步，如果复制下载好的名字不一定是pcl,重命名改一下就好

     cd pcl
     mkdir release
     cd release
     cmake -DCMAKE_BUILD_TYPE=None -DCMAKE_INSTALL_PREFIX=/usr \
           -DBUILD_GPU=ON -DBUILD_apps=ON -DBUILD_examples=ON \
           -DCMAKE_INSTALL_PREFIX=/usr ..
     make
     sudo make install

第四步（可选 and 建议）：如果需要PCLVisualizer 安装OpenNI、OpenNI2

sudo apt-get install libopenni-dev 
sudo apt-get install libopenni2-dev

接下来是测试部分：
在home下建立文件夹 pcl_test

cd pcl_test
vim pcl_test.cpp

pcl_test.cpp如下：

#include <iostream>
#include <pcl/common/common_headers.h>
#include <pcl/io/pcd_io.h>
#include <pcl/visualization/pcl_visualizer.h>
#include <pcl/visualization/cloud_viewer.h>
#include <pcl/console/parse.h>
 
 
int main(int argc, char **argv) {
    std::cout << "Test PCL !!!" << std::endl;
    
    pcl::PointCloud<pcl::PointXYZRGB>::Ptr point_cloud_ptr (new pcl::PointCloud<pcl::PointXYZRGB>);
    uint8_t r(255), g(15), b(15);
    for (float z(-1.0); z <= 1.0; z += 0.05)
    {
      for (float angle(0.0); angle <= 360.0; angle += 5.0)
      {
	pcl::PointXYZRGB point;
	point.x = 0.5 * cosf (pcl::deg2rad(angle));
	point.y = sinf (pcl::deg2rad(angle));
	point.z = z;
	uint32_t rgb = (static_cast<uint32_t>(r) << 16 |
		static_cast<uint32_t>(g) << 8 | static_cast<uint32_t>(b));
	point.rgb = *reinterpret_cast<float*>(&rgb);
	point_cloud_ptr->points.push_back (point);
      }
      if (z < 0.0)
      {
	r -= 12;
	g += 12;
      }
      else
      {
	g -= 12;
	b += 12;
      }
    }
    point_cloud_ptr->width = (int) point_cloud_ptr->points.size ();
    point_cloud_ptr->height = 1;
    
    pcl::visualization::CloudViewer viewer ("test");
    viewer.showCloud(point_cloud_ptr);
    while (!viewer.wasStopped()){ };
    return 0;
}

CMakeLists.txt文件如下：

cmake_minimum_required(VERSION 2.6)
project(pcl_test)
 
find_package(PCL 1.2 REQUIRED)
 
include_directories(${PCL_INCLUDE_DIRS})
link_directories(${PCL_LIBRARY_DIRS})
add_definitions(${PCL_DEFINITIONS})
 
add_executable(pcl_test pcl_test.cpp)
 
target_link_libraries (pcl_test ${PCL_LIBRARIES})
 
install(TARGETS pcl_test RUNTIME DESTINATION bin)
 

然后在pcl_test文件夹下新建一个build文件夹：

mkdir build && cd build
cmake ..                      ##cmake ..代表对上级目录内的CMakeLists进行生成编译文件
make                          ##根据生成的编译文件进行编译
./pcl_test                    ##执行生成的可执行文件

下面是我运的结果，如果是一团变红色，旋转一下鼠标就好啦。
