我正在使用点云库获取深度图,然后每秒左右将 PCD 文件写入内存,以便其他程序可以获取它。
我让程序使用可视化器正确渲染深度图,除了实际写入文件的一行外,它都可以正常工作。
这是我的代码:
#include <pcl/io/openni_grabber.h>
#include <iostream>
#include <pcl/io/pcd_io.h>
#include <pcl/visualization/cloud_viewer.h>
class SimpleOpenNIViewer
{
public:
SimpleOpenNIViewer () : viewer ("PCL OpenNI Viewer") {}
void cloud_cb_ (const pcl::PointCloud<pcl::PointXYZ>::ConstPtr &cloud)
{
if (!viewer.wasStopped())
viewer.showCloud (cloud);
//this is the line to write the file.
//I am not sure it is the correct location.
pcl::io::savePCDFileASCII ("test_pcd_here.pcd", cloud);
}
void run ()
{
pcl::Grabber* interface = new pcl::OpenNIGrabber();
boost::function<void (const pcl::PointCloud<pcl::PointXYZ>::ConstPtr&)> f =
boost::bind (&SimpleOpenNIViewer::cloud_cb_, this, _1);
interface->registerCallback (f);
interface->start ();
while (!viewer.wasStopped())
{
boost::this_thread::sleep (boost::posix_time::seconds (1));
}
interface->stop ();
}
pcl::visualization::CloudViewer viewer;
};
int main ()
{
SimpleOpenNIViewer v;
v.run ();
return 0;
}
这是我在尝试 cmake 文件时遇到的错误:
