Parameter analysis of disc fitting method

Abstract

The Disc Fitting method is an point cloud processing algorithm which can calculate the elevation of the ground surface in a position. This result depends on two parameters: an radius (R) and an quantile (q), because the Fitting Disc method selects the points of the cloud that are nearest the examined position that R, and fit a plane (a disk) to this area whose three sectors contain q quantile of the points under the plane. This article describes some study about the accuracy of the Disc Fitting method with different R and q parameters.
