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! Fri, 15 Nov 2019 08:30:30 -0600https://answers.ros.org/question/337731/laser_msgs-filter-linear-regression-ros-kinetic-c/Comment by stevemacenski for <p>Hey everybody, </p>

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.Fri, 15 Nov 2019 11:12:04 -0600https://answers.ros.org/question/337731/laser_msgs-filter-linear-regression-ros-kinetic-c/?comment=337744#post-id-337744
