Abstract
Mid-range and long-range laser scanners are useful for measuring large-scale engineering facilities. In this paper, we discuss a solid modeling system based on point-clouds captured from engineering facilities. When an engineering facility is measured by a laser scanner, the location of the scanner is restricted in most cases. Components of the engineering facility are only scanned from one side, and they are sometimes partially occluded by other components. To construct solid models using incomplete point-clouds, we propose a new image-based modeling approach combined with point-based modeling techniques. Since point-clouds captured by mid/long-range scanners have reflectance values as well as coordinates, their reflectance images can be used for image-based modeling. We show that our image-based modeling approach is useful for interactively complementing missing information. In addition, we show how to extract shape parameters as precisely as possible by considering industrial standards, assembly constraints, and user-specified constraints.
