AI Technical Summary

Technical Problem

In the prior art, the map alignment method between head-mounted devices and peripheral devices is inefficient and places a huge burden on processing resources.

Method used

By acquiring keyframes from the host device and client device at preset time points, the host device generates the first client pose, and the client device aligns the client map with the host map. Combined with feature extraction localization technology and time synchronization, efficient map alignment is achieved.

Benefits of technology

It achieves map consistency across multiple device systems, reduces the burden on processing resources, and enhances the user's immersive experience.

Abstract

This disclosure provides a map alignment method, a multi-device system, and a non-transitory computer-readable storage medium. The multi-device system is used to operate in a physical environment and includes a host device and client devices. The map alignment method includes: acquiring host-side keyframes and client-side keyframes at preset time points via the host device and client device, respectively; generating a first client pose via the host device based on the host-side keyframes; and aligning the client map established by the client device based on the first client pose with the host-side map established by the host device based on the physical environment detected by the client device. By generating keyframe pairs between the host device and client device, the client device can continuously align the client map with the host map using the pose corresponding to the host-side keyframes. This allows the multi-device system to efficiently achieve map consistency among multiple devices and has advantages such as lower processing resource burden.
