Abstract

An embodiment of the invention discloses a map data processing method, device, equipment and medium. The method comprises the following steps: determining corresponding map levels according to the current running condition of vehicles, wherein the number of the map levels is two at least, and map data of each map level comprise at least two map elements; and updating the map data according to thecorresponding map levels. By the technical scheme of the embodiment of the invention, the problems that the using efficiency of map information resources is not high, and map information cannot meet requirements are solved, updating of the map data and optimization of a using strategy are realized, effects of maps are played effectively, and consumption of treatment resources is reduced.

Description

technical field [0001] Embodiments of the present invention relate to computer data processing technology, and in particular to a method, device, equipment and medium for processing map data. Background technique [0002] Most of the current self-driving vehicles are equipped with a large number of sensors to realize the perception of the surrounding environment, and then control the vehicle according to the perception results. Under special weather and road conditions, the perception results may fail or be misjudged. Therefore, it is necessary to use high-precision maps as assistance, so that the vehicle can predict the road ahead and the environment in advance, and then control the vehicle based on the perception results. It can greatly improve the reliability of automatic driving. [0003] The accuracy of existing high-precision maps has reached the centimeter level, and it contains rich and detailed road traffic information elements. However, the update and use of high...
