Embodiment Construction

[0035] The real-time spatial positioning system based on laser scanning of the present invention includes: a laser emitting scanning part and a laser receiving part.

[0036] Refer to attached figure 1 As shown, the laser emitting scanning part includes two rotors 1 and 2 driven by high-speed motors, two laser emitters 3 and 4, two zero-scale induction sensors 6 and 7, and an infrared LED lamp array 5. Wherein, the rotating shafts 8 and 9 of the two rotors 1 and 2 are perpendicular to each other, and the optimal way is that the rotating shafts 8 and 9 of the two rotors 1 and 2 are arranged perpendicular to each other, as shown in the attached figure 2 shown.

[0037] Specifically: one rotor is horizontally arranged in the positioning space, that is, the horizontal rotor 2 , and the other rotor is vertically arranged in the positioning space, that is, the longitudinal rotor 1 . The two laser emitters 3 and 4 are one-line lasers, which are respectively fixed on the two rotors...

Abstract

The invention discloses a real-time spatial positioning system. The real-time spatial positioning system comprises a laser emission scanning part and a laser receiving part. The laser emission scanning part comprises a 360-degree transverse scanning laser and a 360-degree longitudinal scanning laser, and zero-graduation activation of the scanning lasers is achieved through zero graduation inductive sensors respectively; laser receiving sensors are arranged on a device needing spatial positioning; besides, an infrared LED lamp array is arranged to achieve signal synchronization of laser emission scanning and laser receiving. The invention further discloses a spatial positioning method and a virtual reality device comprising the spatial positioning system. The two perpendicular 360-degree lasers are arranged for emission scanning, and the receiving sensors are arranged for receiving; besides, signal synchronization of laser emission scanning and laser receiving is achieved through zero graduation infrared exposure; in addition, the three-dimensional position of the laser receiving part in a positioning space is accurately obtained by calculating the quartic signal time difference within one working cycle, and thus the real-time accurate positioning effect is achieved. Use is convenient, positioning is accurate, and the refreshing rate is high.

Description

technical field [0001] The invention relates to the technical field of space positioning, in particular to a real-time space positioning system and method and a virtual reality device including the system. Background technique [0002] Existing technologies for indoor positioning include: 1. Technology based on infrared through-beam binocular and multi-eye cameras. The realization of this positioning technology requires the user to carry out professional camera calibration work, as long as the position and angle of the camera change, it needs to be re-calibrated. Moreover, the positioning business depends on the coverage field of view of the camera. The larger the field of view, the more cameras are required. The more cameras, the more complicated the calibration work of the whole system, and the more complicated the data fusion. 2. There is also indoor positioning technology based on UWB ultra-wideband. The realization of this positioning technology requires more than thr...
