US 2013/0211699 A1 · PARKING LOT DETECTION USING PROBE DATA

Abstract

Parking lot (18, 20) locations and geometries are discerned from probe data (22) and integrated with a digital map (12) for use in navigation and other map-related activities. The steps of this invention include: identifying the positions in the probe data (22) where cars are probably parked, detecting the positions of parking lots (18, 20), determining the extension and shape of the detected parking lots (18, 20), and adjusting the parking lots (18, 20) into the road network (14). Optionally, the parking lot (18, 20) can be classified and additional attributes computed. Finally, a topological connection of the parking lot (18, 20) is made to the road network (14) during which entrances (34) and exits (36) are identified.

Dependent claims

A method for detecting parking lots from collected probe data for use in digital maps, said method comprising the steps of:

providing a digital map containing a road network of the type corresponding to roads in reality that support vehicular traffic;
providing probe data comprising a plurality of individual probe traces, each probe trace representing the movements of a real life vehicle over the road network;
identifying probe trace candidates contained within the probe data that correspond to at least one predetermined pattern indicative of parking lot behavior;
discerning at least one distinct parking lot from the probe trace candidates;
and
classifying said at least one distinct parking lot based on a pattern of probe data associated with said at least one distinct parking lot, wherein different parking lot classes are represented by different patterns.
