Problems solved by technology

[0003] In the prior art, the attitude of the handle can be determined through an IMU (inertial measurement unit, inertial measurement unit), but the IMU unit cannot determine the spatial position of the handle
In order to determine the spatial position of the handle, multiple camera base stations can be arranged in the space, and the handle can be positioned through the images captured by the camera base stations, but this outside-in (Outside-In) positioning scheme requires more space. Relatively more expensive

Abstract

The invention discloses a method and system for tracking a position of a matched gamepad of a VR (virtual reality) head-mounted device, the matched gamepad of the VR head-mounted device, the matched VR head-mounted device of the gamepad and a VR device. The method includes arranging an infrared light source on a gamepad shell, arranging a binocular infrared camera for shooting the infrared light source on the VR head-mounted device, and measuring spatial attitudes of the gamepad and the VR head-mounted device; computing a related position relation of the gamepad and the VR head-mounted device according to spatial attitude information of the gamepad, spatial attitude information of the VR head-mounted device and image information shot by the binocular infrared camera; determining the spatial position of the gamepad according to the spatial position of the VR head-mounted device and the related position relation of the gamepad and the VR head-mounted device.

Description

technical field [0001] The present invention relates to virtual reality technology, in particular, to a method for tracking the position of a handle matched with a VR head-mounted device, a position tracking system for a handle matched with a VR head-mounted device, and a method for tracking the position of a handle matched with a VR head-mounted device. A handle, a VR head-mounted device matched with the handle, and a VR device. Background technique [0002] In VR (Virtual Reality, virtual reality) technology, it is sometimes necessary to perform motion tracking on the handle to determine the gesture and spatial position of the handle, so as to recognize the user's action or operation. [0003] In the prior art, the attitude of the handle can be determined through an IMU (inertial measurement unit, inertial measurement unit), but the IMU unit cannot determine the spatial position of the handle. In order to determine the spatial position of the handle, multiple camera base ...
