Method for enriching three-dimensional map representation for navigation system for e.g. vehicle, involves creating virtual three-dimensional model using pre-defined location of maximum surface, and item of model of predefined location

摘要

The method (100) involves determining a position of a predefined place (110) without any information about a three-dimensional (3D) shaping, and determining a maximum area for a pre-defined location (120), where the maximum area describes a pre-defined spatial distribution of a two-dimensional (2D) map. An item of a decomposition model is selected (130) using the maximum area. A virtual 3D model is created (140) using the pre-defined location of the maximum surface, the information on the predetermined location and the item of the decomposition model of the predefined location. Independent claims are also included for the following: (1) an information system (2) a computer program product comprising a set of instructions for a method for enriching 3D map representation for navigation system.
