Problems solved by technology

In the actual experience process, the VR application lacks interaction with the user. The user usually changes the user's perspective and operates the VR application by turning the VR wearable device or operating the handle paired with the VR wearable device, which fails to provide a strong immersive experience. sense of experience

Abstract

The invention relates to the field of VR technologies, and discloses a spatial position detection method and system and a VR wearing device. The method comprises the steps that the VR wearing device transmits a first radio frequency signal to at least three reference objects in a specific space and receives a first reflected signal transmitted by each reference object for the first radio frequency signal; according to the time of receiving the first reflected signal transmitted by a reference object and the time of transmitting the first radio frequency signal, the relative distance between the reference object and the VR wearing device in a particular space is acquired, and at least three relative distances are acquired according to at least three reference objects; the spatial position information of the VR wearing device in the particular space is acquired according to at least three relative distances; the spatial position information is transmitted to a VR host device; the VR host device carries out processing according to the spatial position information to acquire a virtual environment, and the virtual environment is received and displayed; the real environment position of a user is detected in real time and used as the control input of the virtual environment; and the immersive experience of the user in the virtual environment is improved.

Description

technical field [0001] The present invention relates to the technical field of virtual reality (VR for short), in particular to a spatial position detection method, system and VR wearable device. Background technique [0002] VR technology integrates computer graphics technology, computer simulation technology, sensor technology, network parallel processing and other technologies. It is a technology that provides immersive feeling in an interactive three-dimensional environment generated on a computer. The three-dimensional environment is called the virtual environment (Virtual Environment, referred to as VE). Devices based on VR technology (such as VR wearable devices) can provide various VR applications, and in the VR applications, output a virtual environment with immersive experience for users. In the actual experience process, the VR application lacks interaction with the user. The user usually changes the user's perspective and operates the VR application by turning t...
