Abstract

Information processing methods and devices for instant positioning and map construction are disclosed. The method is applied to a mobile electronic device, which is used for real-time positioning and mapping (SLAM) of an unknown environment. The unknown environment at least includes a first scene and a second scene; it is characterized by: , the method includes the following steps: obtaining a frame of observation data; performing SLAM based on the current frame and the valid historical frame of the first scene, and adding the current frame to the first scene if the current frame meets the first predetermined condition. Valid historical frame; when the first scene meets the second predetermined condition, determine whether the second scene exists; if the second scene does not exist, create the second scene, otherwise the current frame is added as a valid frame of the second scene; when the second scene When the second scene meets the third predetermined condition, the data of the first scene is discarded, and SLAM is performed with the second scene.

Description

technical field [0001] The invention relates to an information processing method and equipment for real-time positioning and map construction. More specifically, it relates to an information processing device and method for real-time positioning and map construction in an unknown environment including at least a first scene and a second scene. Background technique [0002] Simultaneous Localization and Mapping (SLAM) is currently a hot research topic in robot positioning. 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] When the robot runs for SLAM for a long time, the scale of the scene experienced will continue to expand, and the execution overhead of SLAM will become unacceptable, and ultimately cannot ...
