Problems solved by technology

However, because ultrasonic waves are susceptible to wireless clutter interference and multipath reflection of ultrasonic signals, the distance value measured by the ultrasonic sensor jitters greatly, which in turn leads to poor position accuracy of the external device determined by the distance value, and The motion track of the external device is not smooth
[0005] In addition, the data update frequency of the ultrasonic sensor is low, so that the location of the obtained external device is less consistent and reduces the user experience.

Abstract

The invention discloses an external equipment locating method and device, virtual reality equipment and system. The external equipment is provided with an ultrasonic transmitter and the virtual reality equipment is provided with an ultrasonic receiver, or the virtual reality equipment is provided with the ultrasonic transmitter and the external equipment is provided with the ultrasonic receiver. The method comprises the following steps: according to ultrasonic wave signal information received by the ultrasonic receiver, determining first distance information of the ultrasonic transmitter and the ultrasonic receiver; carrying out filtering processing on the first distance information to obtain second distance information; and according to the second distance information, determining first position information of the external equipment. According to one embodiment of the invention, accuracy of a position, determined by distance value of the ultrasonic transmitter and the ultrasonic receiver, of the external equipment is improved, and the motion track of the external equipment is smoother.

Description

technical field [0001] The present invention relates to the field of virtual reality technology, and more specifically, to a positioning method for an external device of a virtual reality device, a positioning device for an external device of a virtual reality device, a virtual reality device, and a virtual reality system. Background technique [0002] Virtual reality (Virtual Reality), referred to as VR technology, is to use virtual reality equipment to simulate a three-dimensional virtual world, providing users with simulations of vision, hearing, touch and other senses, so that users can feel as if they are in the scene. Observe things in three-dimensional space in time and without limitation. [0003] Developers are now paying more and more attention to the simulation of the user's immersive experience in a virtual reality environment. The immersive experience may be a hand game experience, and may also be a foot game experience. For example, virtual reality headsets c...
