我有 2 套 pf pcd 文件,它们中的数据在点数方面相似,但 pcd 文件的加载时间仍然存在巨大差异(8 倍以上)。以下行显示相同。
suraj@suraj:~/PCL_Project/Data$ pcl_viewer PCD/000000.pcd
The viewer window provides interactive commands; for help, press 'h' or 'H' from within the window.
> Loading PCD/000000.pcd [PCLVisualizer::setUseVbos] Has no effect when OpenGL version is ≥ 2
[done, 143 ms : 115385 points]
Available dimensions: x y z intensity
suraj@suraj:~/PCL_Project/Data$ pcl_viewer 0001/data1.pcd
The viewer window provides interactive commands; for help, press 'h' or 'H' from within the window.

我想看这些文件的头部,如何打印一个pcd文件的头部信息?
