pointcloud_to_laserscan parameter min_height
hey guys,
short question:
Is the pointcloud_to_laserscan package capable of using negative values as min_height?
Background information: I'm desperatly trying to get a scan out of my PointCloud2 data, that my kinect generates - as it happens the kinect is not on the ground level, which means that some obstacles have negative height values... that somehow seems to be a problem for the node - the obstacles are part of the pcl, but the laserscan does not see them... I hope you get what my problem is, for sure I can't be the first to try this :(
Edit: Update As a workaround I've changed some part of the cloud_to_scan.cpp file and manually increased the height - this works, even though I don't understand why -y+1 < min_height with min_height =0 works, wenn -y < min_height with a value of -1 fails...
I mean, if y is like 0.5 in the first case it is: -0.5+1 <0 => 0.5 < 0 => false in the second case: -0.5 < -1 => false
Edit:
Thanks for your answer, that indicates that somehow I messed up my package. I'm sure that I set the parameters correct in the launchfile, and just to check that I changed the default values - with no result.
