I am a Portuguese Master Degree's student and I am currently developing my Master Thesis which Theme is "People Detection from Laser Range Data".

I have already developed my Detector and I have already got results from a bunch of bagfiles that I recorded with a MOnarCH robot, but now I need to compare them to see if my method is, at least, acceptable.

To that matter I am using your leg_detector however, for a Bagfile with only one static people in the scenario under analysis all the time, leg_detector sees at least 10.

This results are obtained by echoing the topic (people_tracker_measurements).

The following link is for you to download the bagfile that I have recorded if you want to check the results, mentioned above, by yourself.

Link for the bagfile:

Thanks in advance.

In my usage of the leg detector, I too found that it had a high number of false positives. My usual solution was to ignore laser points that matched the static map using map_laser
