Problems solved by technology

Like the first positioning method, the second positioning method also needs to arrange laser emitters around the scene, and will also be affected by occlusion
In addition, the above two methods will strictly limit the user's range of activities, and positioning will fail if the range is exceeded
Moreover, the existing inertial motion capture equipment technology cannot provide accurate spatial positioning

Embodiment Construction

[0067] Below in conjunction with accompanying drawing, further describe the present invention through embodiment, but do not limit the scope of the present invention in any way.

[0068] The invention provides a space positioning device and a positioning method in a virtual reality system. By wearing one or more cameras on the human body, the cameras are fixed on the parts of the human body through a stabilizer or a pan-tilt, and image information is continuously acquired according to the cameras. The image processor analyzes and processes the image information to judge the displacement of the human body, which simplifies the arrangement of peripheral equipment such as cameras in VR positioning scenes, and is more convenient to use.

[0069] figure 1 It is a schematic diagram of the imaging principle of the camera; figure 1 In , the actual object is imaged on the photosensitive sheet through the lens, where α is the angle of view when the camera is shooting; W is the actual s...

Abstract

The invention discloses a space positioning device and positioning method used in a VR (virtual reality) system. The device comprises a camera posture calibration module, a camera posture fixing module, an initialized image collecting processing module and a continuous image processing module, wherein one or more than one camera is worn on the human body; the camera is fixed on the human body positions; in the human body moving process, the continuously collected image is subjected to image processing; the movement of the camera in the axial direction and the moving distance and direction of the camera in the plane vertical to the axial line are obtained through calculation; the human body displacement is obtained. Therefore the space positioning in the VR system is realized. By using the technical scheme, the positioning device and the positioning method have the advantages that peripheral equipment such as arrangement cameras in VR positioning scenes can be simplified, and the use is more convenient.

Description

technical field [0001] The invention relates to virtual reality and augmented reality technologies, in particular to a space positioning device and a positioning method in a virtual reality system. Background technique [0002] Virtual reality (VR) or augmented reality (AR) technology (collectively referred to as VR technology in the present invention) is to produce a visual, auditory, tactile virtual environment or a real environment in a specific range through computer technology and various sensor technologies. Do overlay effect overlay. [0003] In the VR system, many application scenarios involve indoor space positioning, and the use of indoor space positioning technology can achieve better interaction between the real world and the virtual world. However, the existing indoor space positioning technology mainly adopts the following two methods: the first is to arrange reflective points on the human body, and collect images of these reflective points by arranging multip...
