Abstract: Pointcloud processing, especially for use with Building Intelligence Modelling (BIM). A method of processing a point cloud to create a representation of objects in the point cloud, the method comprises: superimposing a grid of cubes over the point cloud; and for each cube in the grid, fitting a plane to the points in the cube, using the points in the cube and its neighbouring cubes, to produce a cube plane, and using the cube planes to derive a surface mesh of polygons.

Abstract: Methods and apparatuses are described for generating three-dimensional representations of sets of objects automatically from point cloud data of those sets of objects. The methods and apparatuses partition the space occupied by the objects into a plurality of volumes. If points within a volume approximately coexist on a surface, such a volume is designated a surface volume. Surface volumes with approximately coplanar surfaces are combined to form larger surface volumes. If points within a volume approximately coexist on a line, such a volume is designated a line volume. Line volumes with approximately collinear lines are combined to form larger line volumes.
