Abstract

The invention provides a high-precision map updating method and device and a storage medium. The method comprises the following steps of obtaining a crowdsourcing image uploaded by a crowdsourcing vehicle terminal, wherein each image carries the position information when the corresponding vehicle terminal collects the image; based on the crowdsourcing images and a high-precision map database, determining the effective change elements of the current high-precision map and the position information of the effective change elements; and obtaining the video data uploaded by the first vehicle terminal set according to the position information carried by each image and the position information of the effective change elements, and updating the high-precision map database according to the video data uploaded by the first vehicle terminal set. According to the technical scheme, the updating of the high-precision map database is based on the image and video information uploaded by a crowdsourcing vehicle terminal, the collection by using an expensive collection vehicle is not needed, the updating speed is high, the timeliness of map updating can be ensured, and the driving safety problem of an automatic driving vehicle is avoided.

Description

technical field [0001] The present application relates to the technical field of automatic driving, and in particular to a high-precision map updating method, device and storage medium. Background technique [0002] HD maps are designed specifically for autonomous vehicles and include road definitions, intersections, traffic signals, lane rules, and other elements for vehicle navigation. Since high-precision maps can provide detailed information about the driving environment to ensure the safety of autonomous vehicles, how to ensure timely updates of high-precision maps is the key to ensuring the safety of autonomous driving. [0003] In the high-precision map update scheme of the prior art, high-precision sensors such as laser point cloud sensors and irrigation equipment installed on special acquisition vehicles are usually used to collect road trajectory data, and upload them to the cloud server. The map is updated with the received road trajectory data. [0004] However...
