Problems solved by technology

[0002] In related technologies, in some indoor areas with weak GPS signals or GNSS (Global Navigation Satellite System, Global Navigation Satellite System) signals, such as indoor parking lots, there is generally no map. Therefore, when the user's vehicle enters the indoor parking area In the field, since there is no map of the indoor parking lot, if the user is not familiar with the internal environment of the indoor parking lot, the user will easily get lost in the indoor parking lot, causing the user to spend a lot of time looking for a parking space

Abstract

The invention discloses a map generation method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining a plurality of pieces of track data, the track data comprises the position and posture information of a vehicle and a bird's-eye view splicing image associated with the position and posture information of the vehicle; performing road element identification on each aerial view spliced image, and determining road elements in each aerial view spliced image; generating first point cloud trajectory data corresponding to the trajectory data according to the road elements in the aerial view spliced images and the vehicle pose information associated with the aerial view spliced images; splicing the first point cloud trajectory data corresponding to the multiple pieces of trajectory data to obtain a point cloud base map; and by taking the point cloud base map as an alignment medium, carrying out alignment fusion on the second point cloud track data and the point cloud base map to obtain a map. The scheme can be applied to map generation of areas with weak navigation signals.

Description

technical field [0001] The present application relates to the field of map technology, and more specifically, to a map generation method, device, electronic device, and storage medium. Background technique [0002] In related technologies, in some indoor areas with weak GPS signals or GNSS (Global Navigation Satellite System, Global Navigation Satellite System) signals, such as indoor parking lots, there is generally no map. Therefore, when the user's vehicle enters the indoor parking area In the parking lot, since there is no map of the indoor parking lot, if the user is not familiar with the internal environment of the indoor parking lot, the user will easily get lost in the indoor parking lot, causing the user to spend a lot of time looking for a parking space. Contents of the invention [0003] In view of the above problems, the embodiments of the present application propose a method, device, electronic device, and storage medium for generating a map, so as to improve ...
