Abstract

The invention belongs to a VR helmet positioning method. In order to solve the problem that in the positioning technology applied to VR glasses at present, the setting operation is inconvenient and the setting is more complex when the VR helmet positioning method is particularly used for a 360-degree rotating motion platform, the invention provides a VR helmet positioning method suitable for a rotating platform, which comprises the following steps: S1, determining the spatial orientation zero position reference, the rotating angle zero position reference and the rotating positive direction ofthe rotating platform; s2, according to the space orientation zero position reference, the rotation angle zero position reference and the rotation positive direction, obtaining the current space orientation and the rotation angle of the rotation platform; s3, acquiring a relative position and a relative spatial orientation of the VR helmet and any fixed position on the rotating platform; s4, performing superposition calculation to obtain the spatial orientation of the VR helmet in the real physical space; and S5, adjusting the image in the VR helmet according to the spatial orientation of theVR helmet in the real physical space and the relative position between the VR helmet and any fixed position on the rotating platform, so as to enable the virtual space to be matched with the real physical space.

Description

technical field [0001] The invention relates to a VR helmet positioning method, in particular to a VR helmet positioning method suitable for a rotating platform. Background technique [0002] Positioning technology plays a vital role in the practical application of VR glasses, and requires millimeter-level positioning accuracy and millisecond-level positioning speed to achieve a smooth VR interactive experience. This also means that there are relatively high requirements on the manufacturing process and cost of the positioning device itself. [0003] At present, in practical applications, VR positioning devices usually use at least two positioning units placed diagonally to achieve 360-degree omnidirectional positioning. In addition, complex setting operations such as demarcating the range, measuring the height of the horizon, and adjusting the angle are required during the initial setting. Especially for the positioning of VR glasses on a motion platform that can rotate 3...
