AI Technical Summary

Technical Problem

Existing XR positioning technology cannot simultaneously achieve precise positioning and flexible deployment of joints throughout the body. Out-to-in technology is costly and cannot be moved, while in-to-out technology cannot position the wrists and ankles, increasing the burden on players.

Method used

By utilizing the player's glasses camera to observe the opponent in a competitive XR game, combined with field anchor points and 6DoF autolocalization, cross-device collaborative triangulation is achieved to calculate the world position of each player's key points, reducing the need for additional sensors.

Benefits of technology

It enables precise positioning of the wrist and ankle in XR combat games without the need for additional wearable sensors, reducing costs and the burden of wearing them, and improving the gaming experience.

Abstract

The application discloses a method and system for body positioning in a face-to-face confrontation XR game, and relates to the technical field of spatial positioning in a confrontation XR game. In the face-to-face confrontation XR game, the glasses camera of an opponent player is used as an outward-inward sensor, and the world coordinates of key points such as the glasses center, left and right wrist, and left and right ankle of each player are calculated through triangulation in cooperation with the outward-inward 6DoF positioning of each pair of glasses. In the game, precise body positioning can be realized without wearing any additional sensors at the positions of the wrist, ankle and the like.
