Problems solved by technology

However, in the actual application process, the driving trajectory data obtained by the vehicle is often complicated and has a lot of redundant data, and due to user behavior habits, a large amount of trajectory data overlaps, which has no reference value, resulting in the process of obtaining the map road network. There are more invalid processing

Embodiment Construction

[0018] In order to enable those skilled in the art to better understand the solutions of the present application, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application.

[0019] At present, the development of automobile intelligence is rapid, and there are many usage scenarios and functions of automobiles, but most of them are about the extended application of vehicles in the process of driving on the road. some problems. For example, most of the parking lots are in the underground environment, the GPS signal is weak, and the vehicle positioning ability is poor, so it is not easy to realize the navigation in the parking lot. Moreover, it is difficult to obtain the navigation map of the parking lot, so that the automatic driving of the vehicle in the parking lot lacks the support of positioning and maps.

Abstract

The invention discloses a map road network updating method and device, computer equipment and a storage medium, and the method comprises the steps: obtaining the driving track data of a vehicle in a parking lot, obtaining a first matching rate used for representing the matching probability of a track point in the track data and a node in a target map road network, the second matching rate is used for representing the probability that a target node exists in nodes matched with the track points in the target map road network; and based on the first matching rate and the second matching rate, determining whether the driving track data meets a preset updating condition, and if the preset updating condition is met, updating the target map road network based on the driving track data. According to the method, the driving tracks of a plurality of vehicles in the parking lot can be screened, and the parking lot map road network is updated based on the screened driving tracks.

Description

technical field [0001] The present application relates to the technical field of map processing, and more particularly, to a method, device, computer equipment and storage medium for updating a map road network. Background technique [0002] In the process of realizing the intelligentization of automobiles, in order to make the application range wider, the vehicle can obtain the map road network of the parking lot by obtaining the driving trajectory data of the vehicle in the parking lot, and then navigate the parking of the vehicle based on the map road network. and positioning. However, in the actual application process, the driving trajectory data obtained by the vehicle is often complicated and there is a lot of redundant data, and due to user behavior habits, a large amount of trajectory data overlaps, which has no reference value, which leads to the process of obtaining the map road network. There are many invalid processes. SUMMARY OF THE INVENTION [0003] In vie...
