Handle positioning method and device in head-mounted display system and head-mounted display system

Abstract

The invention discloses a positioning method and device for a handle in a head-mounted display system and the a head-mounted display system. The method comprises the steps that wireless radio frequency master equipment on head-mounted equipment in the head-mounted display system is used for executing the operation of pairing with wireless radio frequency slave equipment of a first handle and wireless radio frequency slave equipment of a second handle; R; receiving electromagnetic waves emitted by the first handle and the second handle by using an electromagnetic wave receiver on the head-mounted equipment and generating an induced electromotive force; A; and according to the induced electromotive force, pose information corresponding to the first handle and pose information corresponding to the second handle are obtained through calculation, positioning is completed, and the pose information comprises position translation information and direction rotation information when the wearer wears the first handle or the second handle to move. According to the embodiment of the invention, t, through electromagnetic positioning, t, the handle data jitter is reduced, and the handle space positioning precision is improved.

Description

Technical field [0001] The invention relates to the field of head-mounted display technology, in particular to a method and device for positioning a handle in a head-mounted display system, and a head-mounted display system. Background technique [0002] With the gradual maturity of head-mounted display technology, various technologies around virtual display devices have also developed rapidly, including virtual reality (Virtual Reality, VR), augmented reality (Augmented Reality, AR), and mixed reality ( Mix Reality, referred to as MR) and so on. Among them, VR is to completely immerse users in the virtual world, AR is to add virtual information to the real environment to enhance the real environment, and MR is to mix the real world and virtual world to produce a new visual environment. The new visualization environment contains both physical entity and virtual information. [0003] In the above-mentioned VR, AR or MR systems, the positioning and tracking of the handle basically ...

AI Technical Summary

Problems solved by technology

[0003] In the aforementioned VR, AR, or MR systems, the positioning and tracking of the handle basically adopts an optical solution. In order to solve the problem of being easily occluded and realize 6-DOF space positioning, it is often arranged by arranging multiple cameras or multiple light towers, and at the same time, the HMD ( Head Mount Display, head-mounted display) and the handle add multiple feature points to minimize the blind area, but due to the influence of the field of view and other effects, the blind area problem cannot be fundamentally solved, and the spatial positioning of the 6-degree-of-freedom movement of the hand is realized. Difficult. At the same time, due to the low frequency of the spatial positioning data of the camera, the delay at the handle end is relatively large, and the accuracy is poor in the edge area of ​​the field of view.
