Self-adaptive intelligent head-hand VR system and method

Abstract

The invention provides a self-adaptive intelligent head-hand VR system, which comprises a head-mounted device, a handle, a control terminal and an electromagnetic module, and is characterized in thatthe head-mounted device is provided with a head-mounted camera, and the head-mounted camera is used for acquiring an external environment image of a head-mounted coordinate system; a handle camera isarranged on the handle and is used for acquiring an external environment image of a handle coordinate system; the control terminal comprises a control end database and a data selection module; a control terminal database is used for storing an external environment image of the handle coordinate system; wherein the data selection module is used for judging a tracking mode adopted by the tracking handle, the tracking mode comprises optical tracking and electromagnetic tracking, the electromagnetic module is connected with the data selection module, and if the optical tracking is adopted, the electromagnetic module is used for carrying out coordinate system conversion on an external environment image of a head-mounted coordinate system and an external environment image of a handle coordinatesystem; and thus, the external environment image acquired by the head-mounted camera and the external environment image acquired by the handle camera are in the same coordinate system, and optical tracking is completed.

Description

technical field [0001] The present invention relates to the field of computer vision, and more specifically, to an adaptive intelligent head-hand VR system and method. Background technique [0002] At present, in the field of VR vision, most of the existing All-in-one VR 6DOF all-in-one machine designs support 6DOF tracking of the head, and judge the relative position relationship between the headset and the handle through optical, ultrasonic, electromagnetic and other solutions. On the basis of wear, the position of the handle is converted into the world coordinate system of the handle through the mapping of the relative relationship. In the above schemes, optical tracking has optical limitations, and ultrasonic tracking has interference problems such as FOV limitations, external reflections, and occlusions. The electromagnetic tracking solution also has the problem of external magnetic field interference, and there is no solution solution that can effectively solve the abo...

Problems solved by technology

[0004] In view of the above problems, the purpose of the present invention is to provide an adaptive intelligent head-hand VR system to solve the FOV limitation of the existing All-in-one VR 6DOF all-in-one machine design if optical tracking is adopted, and if ultrasonic tracking is used, there is FOV limitation , external reflection, occlusion and other interference problems, if the electromagnetic tracking solution is used, there will also be external magnetic field interference problems, resulting in poor anti-interference ability and low accuracy of the VR system
