一、环境 
Win10 X64 
VS2015 
PCL1.8.0AllinOne

二、代码

#include "stdafx.h"
#include <pcl/point_types.h>
#include <pcl/io/pcd_io.h>
#include <pcl/kdtree/kdtree_flann.h>
#include <pcl/features/normal_3d.h>
#include <pcl/surface/gp3.h>
#include <pcl/visualization/pcl_visualizer.h>
#include <pcl/io/pcd_io.h>
#include <pcl/features/integral_image_normal.h>
#include <boost/thread/thread.hpp>
#include <pcl/visualization/pcl_visualizer.h> int main(int argc, char** argv)
{
//加载点云模型
pcl::PointCloud<pcl::PointXYZ>::Ptr cloud(new pcl::PointCloud<pcl::PointXYZ>);
// pcl::PCLPointCloud2 cloud_blob;
if (pcl::io::loadPCDFile<pcl::PointXYZ>("rabbit.pcd", *cloud) == -) { PCL_ERROR("Could not read file \n");
}
//* the data should be available in cloud // Normal estimation*
//法向计算
pcl::NormalEstimation<pcl::PointXYZ, pcl::Normal> n;
pcl::PointCloud<pcl::Normal>::Ptr normals(new pcl::PointCloud<pcl::Normal>);
//建立kdtree来进行近邻点集搜索
pcl::search::KdTree<pcl::PointXYZ>::Ptr tree(new pcl::search::KdTree<pcl::PointXYZ>);
//为kdtree添加点云数据
tree->setInputCloud(cloud); n.setInputCloud(cloud);
n.setSearchMethod(tree);
//点云法向计算时,需要搜索的近邻点大小
n.setKSearch();
//开始进行法向计算
n.compute(*normals);
//* normals should not contain the point normals + surface curvatures // Concatenate the XYZ and normal fields*
//将点云数据与法向信息拼接
pcl::PointCloud<pcl::PointNormal>::Ptr cloud_with_normals(new pcl::PointCloud<pcl::PointNormal>);
pcl::concatenateFields(*cloud, *normals, *cloud_with_normals); /*图形显示模块*/
//显示设置
boost::shared_ptr<pcl::visualization::PCLVisualizer> viewer(new pcl::visualization::PCLVisualizer("3D Viewer")); //设置背景色
viewer->setBackgroundColor(, , 0.7); //设置点云颜色,该处为单一颜色设置
pcl::visualization::PointCloudColorHandlerCustom<pcl::PointXYZ> single_color(cloud, , , ); //添加需要显示的点云数据
viewer->addPointCloud<pcl::PointXYZ>(cloud, single_color, "sample cloud"); //设置点显示大小
viewer->setPointCloudRenderingProperties(pcl::visualization::PCL_VISUALIZER_POINT_SIZE, , "sample cloud"); //添加需要显示的点云法向。cloud为原始点云模型,normal为法向信息,10表示需要显示法向的点云间隔,即每10个点显示一次法向,5表示法向长度。
//viewer->addPointCloudNormals<pcl::PointXYZ, pcl::Normal>(cloud, normals, 1, 0.01, "normals");
viewer->addPointCloudNormals<pcl::PointNormal>(cloud_with_normals, , 0.5, "normals");
//--------------------
while (!viewer->wasStopped())
{
viewer->spinOnce();
boost::this_thread::sleep(boost::posix_time::microseconds());
} // Finish
return ();
}
