AI Technical Summary

Technical Problem

In collaborative interaction among multiple VR terminals, when occlusion causes interruption of visual tracking of virtual characters, existing technologies lack effective pose maintenance and transition mechanisms, resulting in abrupt changes in the position and posture of virtual characters, which seriously damages the immersive experience and spatial consistency.

Method used

A collaborative perception network is constructed by exchanging visual and ranging data among multiple VR terminals. Each terminal evaluates the credibility of the virtual character's pose, broadcasts the last observation information when occlusion interrupts, and determines the pose constraint boundary by combining the observation credibility. The virtual character's skeletal key point trajectory is predicted and the pose transition is adjusted.

Benefits of technology

It effectively avoids visual jumps when virtual characters are interrupted by occlusion, ensures the consistency of the virtual world state, and enhances the immersive experience of multi-user collaboration.

Abstract

This application provides a multi-VR terminal collaborative interaction system and method based on mutual positioning computation, relating to the field of VR terminal collaborative interaction technology. It involves constructing a collaborative perception network; evaluating the pose reliability of the virtual character mapped to each VR terminal in the collaborative perception network to obtain the observation reliability of each virtual character's pose; when all VR terminals detect a virtual character with lost visual observation, the collaborative perception network broadcasts the last observation information of the lost virtual character to determine the pose constraint boundary of the lost virtual character during the VR terminal occlusion interruption; predicting the trajectory of the skeletal keypoints of the lost virtual character to obtain the predicted motion trajectory of the virtual character's skeletal keypoints; and performing a pose transition on the lost virtual character to obtain the virtual character's pose transition parameters, thereby adjusting the virtual character's spatial position. This application can prevent visual jumps in virtual characters when VR terminal occlusion interruption occurs.
