pcl coordinate system orientation
I am aware that ros uses the positive coordinate system in which x=forward, y=left, and z=up, but can anyone tell me what pcl data uses?

The same, in whatever frame of reference the PointCloud2 message specifies.

joq, that's what I thought until I used the function pcl::fromROSMsg() and a pcl passthrough filter. The PCL z parameter pertained to forward direction and y pertainted to the upward direction. I'm speaking in terms of the pcl namespace. Is this correct?
Check the
header.frame_id
field in the message. It may be using an "optical" frame by mistake. See: http://www.ros.org/reps/rep-0103.html#coordinate-frame-conventionsThanks for the help!
