Abstract

The invention belongs to the technical field of parking lot map acquisition, and discloses an underground parking lot crowdsourcing map acquisition method. The method comprises the steps of acquiring data information of an Nth area of a parking lot through an Nth acquisition vehicle, and establishing an Nth local map according to the data information of the Nth area; acquiring data information of an (N + 1) th area of the parking lot through an (N + 1) th acquisition vehicle, establishing an (N + 1) th local map according to the data information of the (N + 1) th area, and acquiring positioning information of the (N + 1) th acquisition vehicle in the Nth local map; extracting identifiers of motion tracks and semantic data of the Nth local map and the (N + 1) th local map, and establishing a matching relationship of track shapes and association of the semantic data identifiers; and combining the topological map and the vector semantic map to form a global map. The adaptive time of a new parking lot to the autonomous parking function is shortened, and the map acquisition speed is increased.

Description

technical field [0001] The invention belongs to the technical field of parking lot map collection, and in particular relates to a crowdsourced map collection method for an underground parking lot. Background technique [0002] The autonomous parking system is used to solve the problem of automatic driving of the vehicle from the entrance of the parking lot to the parking space. It is a level 4 fully unmanned driving system with limited scenarios. As an important data source relied on in the field of autonomous driving, high-precision maps can effectively assist the autonomous parking system in positioning and path planning. However, most of the high-precision map collection is usually carried out on the ground and needs to rely on GNSS signals to give reference positions. The establishment of high-precision maps in underground parking lots is complicated due to the lack of relevant reference positioning information and the large number. It is easy to get lost when you are n...
