Abstract

The invention provides a map construction method, a repositioning method, a map construction device, a repositioning device, a computer readable storage medium and electronic equipment, and relates tothe technical field of augmented reality. The map construction method comprises the steps of obtaining a target key frame, performing feature extraction on the target key frame to obtain feature point information of the target key frame, and determining semantic information corresponding to the feature point information of the target key frame; obtaining feature point information of a previous key frame of the target key frame and corresponding semantic information; determining a feature matching result of semantic information matching and feature point information matching between the targetkey frame and the previous key frame; and generating local map point information according to the feature matching result so as to construct a map in combination with the local map point information.According to the invention, the accuracy of feature matching in the augmented reality scheme can be improved, and the accuracy of the mapping and repositioning process is further improved.

Description

technical field [0001] The present disclosure relates to the field of augmented reality technology, and in particular, relates to a map construction method, a relocation method, a map construction device, a relocation device, a computer-readable storage medium, and an electronic device. Background technique [0002] Augmented Reality (Augmented Reality, AR) is a technology that integrates the virtual world and the real world. This technology has been widely used in many fields such as education, games, medical care, Internet of Things, and intelligent manufacturing. [0003] In multi-person AR technology, both mapping and relocation schemes involve the process of feature matching, and feature matching plays a crucial role in AR experience. However, due to the change of viewing angle, distance change and environmental factors between the mapping device and the relocation device, there may be a problem of feature mismatch, resulting in low robustness of mapping and relocation,...
