Polylidar3D -- Fast Polygon Extraction from 3D Data
Jeremy Castagno, Ella Atkins
Flat surfaces captured by 3D point clouds are often used for localization, mapping, and modeling. Dense point cloud processing has high computation and memory costs making low-dime…
Polylidar -- Polygons from Triangular Meshes
Jeremy Castagno, Ella Atkins
This paper presents Polylidar, an efficient algorithm to extract non-convex polygons from 2D point sets, including interior holes. Plane segmented point clouds can be input into Po…
Realtime Rooftop Landing Site Identification and Selection in Urban City Simulation
Jeremy Castagno, Yu Yao, Ella Atkins
Safe autonomous landing in urban cities is a necessity for the growing Unmanned Aircraft Systems (UAS) industry. In urgent situations, building rooftops, particularly flat rooftops…
Automatic Classification of Roof Shapes for Multicopter Emergency Landing Site Selection
Jeremy D. Castagno, Ella M. Atkins
Geographic information systems (GIS) now provide accurate maps of terrain, roads, waterways, and building footprints and heights. Aircraft, particularly small unmanned aircraft sys…
