Adaptive pointcloud segmentation for assisted interactions

Abstract

Figure 1: Our novel interactive approach for shape detection in point clouds allows for sophisticated interactions: Left: A Lasso selection selects only points that lie on the support shape as shown in the top image. Points in front and back of the support shape are not selected (bottom). Middle: A volumetric brush selection is performed on the selected support shape (top). Points are only selected if they belong to the support shape and intersect the brush (bottom). Right: Interactive LoD increment interaction along the selected support shape (drawn in red). The top image shows the original rendering model of the point cloud; the bottom image shows the point cloud with the additional points.
