Hi,

PCL has a RANSAC based method to detect planes from a set of 3d points. One of the user inputs to the SACSegmentation class is a "distance threshold" that's set using the pcl::SACSegmentation::setDistanceThreshold() function. However, the documentation doesn't contain info on how that value is used? What are the units that it expects and is it any different for lines and planes?

This might not be directly related to ROS but I know a lot of robotics developers use the pcl_ros stack so maybe someone has an answer to this (let me know if pcl questions should not go on this website)

Thanks

PCL has a dedicated support forum: www.pcl-users.org. This is more appropriate there.

If you do post there, please comment here with a link to your pcl-users post.
