Claim Text:
1. A computer-implemented method for providing object descriptors for objects in point cloud data for an urban environment by segmenting the point cloud data in a computer that is programmed to perform: obtaining, using a ground-based laser scanner, the point cloud data, wherein the point cloud data is for the urban environment; in a pre-process phase, filtering out, in the computer, terrain points from the point cloud data using ground filtering; after the pre-process phase, segmenting, in the computer, the point cloud data into two or more blocks; combining, in the computer, objects that lie on neighboring adjacent blocks of the two or more blocks based on cell continuity; providing, in the computer, object descriptors for the combined objects; utilizing, in the computer, the object descriptors to process the point cloud data, and facilitate and output a scene interpretation of the urban environment.
