c++pcl读取txt点云数据

可以使用PCL库的PointCloud类读取txt格式的点云数据。具体操作如下：

1. 创建PointCloud对象

pcl::PointCloud<pcl::PointXYZ>::Ptr cloud(new pcl::PointCloud<pcl::PointXYZ>);

2. 读取txt文件

if (pcl::io::loadPCDFile<pcl::PointXYZ>("filename.txt", *cloud) == -1)
{
PCL_ERROR("Couldn't read file test_pcd.pcd \n");
return (-1);
}

3. 遍历点云数据

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;

希望这个回答能够帮到你。
