METHOD AND APPARATUS FOR REPRESENTING MAP ELEMENT AND METHOD AND APPARATUS FOR LOCATING VEHICLE/ROBOT

摘要

A method and an apparatus for representing a map element and a method and an apparatus for locating a vehicle/robot based thereupon. The method for representing a map element comprise: generating a Gaussian Mixture Model for the map element (110); generating a signature for identifying the map element, wherein the signature comprises properties of the map element (120); and generating Gaussian Mixture Model comprises the Gaussian Mixture Model, the signature and an existence probability of the map element (130). A novel technology for representing map elements and an improved vehicle/robot localization technology are provided based thereupon.
