title Abstracting and Trimming Reality - One-Click-Region-Growing and Surface Trimming in Point Clouds

summary Measured point clouds are the cast of the as-built reality. In this paper, we present an approach to derive a partially closed surface model from a point cloud. Without using fully-automated methods we instead leverage the users abstract thinking towards a half-automated approach. Hence we present our algorithm for a one click region growing in point clouds and intersecting and trimming those regions to achieve a partially watertight surface model.
