Method and System for Semantic Labeling of Point Clouds

摘要

A system for assigning a semantic label to a three-dimensional (3D) point of a point cloud includes an interface to transmit and receive data via a network, a processor connected to the interface, a memory storing program modules including a communicator and a labeler executable by the processor. In this case, the communicator causes the processor to perform operations including establishing, using the interface, a communication with an external map server storing a map defined in a map coordinate system, determining a location on the map corresponding to the 3D point, and querying the map using the location to obtain an information relevant to the semantic label at the location in the map, wherein the labeler causes the processor to determine the semantic label of the 3D point using the information.
