Map updating method, map fusion updating method, terminal and server

Abstract

The invention provides a map updating method, a map fusion updating method, a terminal and a server, and the map updating method comprises the steps: collecting the terrain information of an operationregion with a changed terrain after the operation is completed; and forming a first vector boundary according to the topographic information, and updating the current map. Aiming at the situation that the terrain is changed after operation, the map is automatically updated by collecting the changed terrain information, and the map updating efficiency is ensured; furthermore, the collected topographic information is uploaded to the server side and is accurately calculated by the server side, the map element increment accurate vector boundary is returned, the map is further updated, and the mapupdating accuracy is improved.

Description

Technical field [0001] The present disclosure relates to the field of information processing, and further relates to map update applied to automatic driving in mining areas, and also relates to a map update method, a map fusion update method, a terminal for implementing the map update method, and a server for implementing map fusion update. Background technique [0002] In today’s society, electronic maps are like another pair of eyes to facilitate people’s life and work, such as automatic driving or manual driving on public roads, or driving in a closed environment. For example, a relatively closed environment in a mining area is autonomous driving. One of the best choices for technology landing scenarios. The key technologies of autonomous driving involve environment perception, high-precision positioning, decision-making planning, execution control, etc. Among them, high-precision maps are highly accurate due to their high-precision, high-granularity, and real-time characterist...

AI Technical Summary

Problems solved by technology

The existing high-precision map update is often a low-frequency update of the public environment, which is difficult to apply to environments with a relatively fast update frequency (such as minutes or even seconds) (such as open areas in mining areas such as loading areas, dumps, etc.)
