Hey everybody,

I am trying to use the Laser Data(sensor_msgs/LaserScan) to get the exact position of an reflective marker. Therefore, I want to filter the data a little bit:

  1. Filter; Intensity filter
  2. Filter: Range filter
  3. Filter: Angular Bounds filter
  4. Filter: Median Filter

Once I have run all the filters I would like to execute linear regression on the data to make sure, that all the points are on the same line. I just found the laser_filters package, which can help me a lot to run the first four filters on the data. But I am still looking for a linear regression package. Is there a package for this specific issue?

Thanks in advance!

This is a fairly simple algorithm, I don't know that its worth having a "ROS" specific package for it. You clearly know you need to do it and its pretty simple linear algebra.
