Preparation of 3D models of Trucks for Timber Load Analysis

Abstract

The article describes a unique method of processing scanned point cloud on a moving object with variable speed. Point clouds represent a set of trucks loaded by a scanning gate made up of four 2D laser scanners. Three scanners record the surface of the truck from three sides, the fourth scanner records the longitudinal change of the profile of one of a truck s side. From this profile, the method evaluates the motion movement function by which all other point clouds are recalculated. The result is a modified point clouds representing the surface of the standing set. The article also provides a way of point segmentation that separates the points representing the timber load from the truck.
