A method, device, terminal and storage medium for aligning multiple maps

Abstract

A multi-map alignment method applied to a terminal or a cloud includes: acquiring N maps including description information of map points of a first path (S101); the description information in the N maps being different, N being an integer greater than one; selecting a map from the N maps as a reference map, the remaining maps being used as correction maps (S102); adjusting the description information of the map points of the first path in the correction maps according to the description information of the map point of the first path in the reference map (S103). The present invention also relates to a multi-map alignment device, a terminal and a storage medium.

Description

technical field [0001] The present application relates to the field of computer vision, and in particular to a method, device, terminal and storage medium for aligning multiple maps. Background technique [0002] The current visual simultaneous localization and mapping (vSLAM) technology uses a visual sensor to collect image data and builds a map based on the collected image data. [0003] In the process of researching the prior art, the inventor found that the map established by the vSLAM technology is relativity. For the same path, there are differences between the image data collected by the forward movement and the image data collected by the reverse movement, resulting in differences in the output results of the same position during the positioning process, that is, when the map established by the collected image data is directly used for positioning. , two different results are obtained. Similarly, for two maps with a common path, the above situation also exists in t...
