Abstract

The invention discloses a handle positioning method, head-mounted display equipment and a storage medium. The handle positioning method comprises the steps: emitting a magnetic field signal emitted byan electromagnetic emission module of a handle, and obtaining the electromagnetic pose of the handle according to the magnetic field signal; shooting an optical mark point of the handle to obtain animage, and obtaining the optical pose of the handle according to the image; and fusing the handle electromagnetic pose and the handle optical pose, and realizing the positioning of the handle based ona fused pose. According to the embodiment of the invention, the technical problem that electromagnetic positioning tracking is easy to lose is avoided, the limitation of a field angle when optical positioning is independently used is broken through, the ambient light interference is reduced, and the positioning precision is improved.

Description

technical field [0001] The present application relates to the field of virtual reality technology, and in particular to a handle positioning method, a head-mounted display device and a storage medium. Background technique [0002] With the vigorous development of the virtual reality (Virtual Reality, referred to as VR) industry, users' demand for head-mounted display device HMD (Head-Mounted Display) interaction is increasing. Capturing hand movements is very important for interactive experience. Currently, Hand positioning and motion capture are easily disturbed by the environment, and the accuracy is not high. Contents of the invention [0003] In view of the above problems, the present application is proposed to provide a handle positioning method, a head-mounted display device, and a storage medium that overcome the above problems or at least partially solve the above problems. [0004] According to an aspect of the embodiments of the present application, a handle pos...
