Does laser_scan_matcher work with scans of more/less than 180 degrees? [closed]

Hi all, I use the package laser_scan_matcher to detect whether a TrutleBot2 robot is stuck (by comparing the matcher pose to the odometry/commanded velocity). It works when I use an hokuyo laser and set min/max angles to -/+ pi/2, but matching fails most of the time if I use the 270 degrees scan. It's even worse if I use the fake laser scan extracted from the kinect by depthimage_to_laserscan. So... looks like laser_scan_matcher must be tweaked to uses non-180 deg scans, right? If so:

  • To the package authors: Would it be very difficult to do so?
  • To everybody: any alternative out there to get odometry from the laser? I tried also to install a camera and run viso2_ros, but didn't work well and takes a lot of CPU.

UPDATE I have created a github issue asking for this change.

Thank you a lot

I'm using a SICK LMS100 with a 270 degree scan with laser_scan_matcher and haven't run into any issues.

you are right! I retried with better combinations of parameters and performance improved regardless the fov
