Abstract

Mid-range and long-range laser scanners are capture dense point-clouds from engineering facilities. The captured point-clouds can be converted to smooth mesh models by using streaming operations. In this paper, we discuss a solid modeling system based on large-scale mesh models. When an engineering facility is measured by a laser scanner, components are scanned only from the limited directions, and they may be partially occluded by other components. To construct solid models using such incomplete mesh models, we introduce modeling and editing operations based on the reflectance images, which can be generated from point-clouds. We also show how to generate 3D models of standard parts.
