在本教程中,我们将学习如何从PCD文件中读取点云数据。
#代码
首先,在你最喜欢的编辑器中创建一个名为pcd_read.cpp
的文件,并在其中放置下面的代码:
#include <iostream>
#include <pcl/io/pcd_io.h>
#include <pcl/point_types.h>
int
main (int argc, char** argv)
{
pcl::PointCloud<pcl::PointXYZ>::Ptr cloud (new pcl::PointCloud<pcl::PointXYZ>);
if (pcl::io::loadPCDFile<pcl::PointXYZ> ("test_pcd.pcd", *cloud) == -1) //* load the file
{
PCL_ERROR ("Couldn't read file test_pcd.pcd \n");
return (-1);
}
std::cout << "Loaded "
<< cloud->width * cloud->height
<< " data points from test_pcd.pcd with the following fields: "
<< std::endl;
for (size_t i = 0; i < cloud->points.size (); ++i)
std::cout << " " << cloud->points[i].x
<< " " << cloud->points[i].y
<< " " << cloud->points[i].z << std::endl;
return (
