LIDAR range scanners are a popular tool for data acquisition in the field of urban modeling, archaeological preservation, city planning, and more. However, range scanners output a series of discrete distance samples as disconnected points, providing a fundamentally incomplete representation of the underlying structure in a scene. Data from a single LIDAR scan of a region can be trivially triangulated,...
Efficient 3D scanning technology has led to acquisition of very large datasets for application areas such as terrain and urban modeling. However, relatively few techniques exist to automatically extract meaningful regions from this data, and the largest datasets examined in the literature rarely exceed millions of points in size. In this paper, we present an efficient algorithm for identification...
