Abstract

The invention discloses an instant positioning and map construction device, system and method. The device comprises an instant positioning and map construction unit which is used for performing instant positioning and map construction in an unknown environment, a communication unit which is used for communicating with an external guide system to obtain direct map or positioning information and further communicating with an external regional server to obtain regional map information, and a processing unit which is used for further amending an instant positioning and map construction result obtained by the instant positioning and map construction unit based on data obtained by the communication unit and simultaneously sending the amended result back to the regional server via the communication unit to facilitate updating of a regional map.

Description

technical field [0001] The invention relates to real-time positioning and map construction equipment, system and method. More specifically, it relates to devices, systems and methods that enable faster and sustainable instant positioning and mapping. Background technique [0002] Simultaneous Localization and Mapping (SLAM) is currently a hot research topic in robot localization. The so-called SLAM is the integration of mobile robot positioning and environmental map creation, that is, the robot builds an incremental environmental map according to its own pose estimation and sensor perception of the environment during the movement process, and uses the map to realize its own positioning. [0003] A robot's navigation performance is limited by its ability to acquire information about its environment (eg, a map) and its current location. Accurate and timely updates of surrounding maps and current location can provide robots with greater degrees of freedom in path finding, pat...
