Problems solved by technology

[0005] The purpose of the present invention is to propose a dynamic detection of VR operating space and parameterized virtual scene reconstruction in view of the fact that the current VR equipment cannot realize the free movement of VR objects in the operating space, and get rid of the current operating mode that is only bound by special fixed seats or fixed platforms. The structure system and method are simple in structure, easy to operate, and superior in performance, and are suitable for capturing and virtualizing experience of composite parameters of three-dimensional entities in various VR operating spaces.

Abstract

The invention relates to a system and method for dynamically detecting VR operation spaces and reconstructing parameterized virtual scenes. The system consists of a laser radar unit, a three-dimensional space imaging unit, a scene virtual unit and a virtual scene reappearance unit. By adoption of the system and method, the free movement of VR using objects in operation spaces can be realized, the existing operation mode restrained in special fixed seats, special fixed platforms and the like is dispensed, three-dimensional space entity composite parameters such as absolute distance parameters, relative distance parameters, time parameters and the like of dynamic and static entities in VR operation spaces can be captured, the VR operation spaces can be virtualized to user appointed virtual scenes according to the obtained three-dimensional space entity composite parameter information, and meanwhile, the data fusion and interactive game experience among a plurality of VR using objects can be realized. The system disclosed by the invention is simple in structure, simple and convenient to operate and excellent in performance, and is suitable for the capturing and virtualization experiences of three-dimensional space entity composite parameters of various VR operation spaces.

Description

technical field [0001] The invention relates to a system and method for reconstructing a virtual scene in a VR running space, in particular to a system and a method for dynamic detection and parameterized virtual scene reconstruction of a VR running space. Background technique [0002] Virtual reality technology (Virtual Reality, VR), that is, the use of computer technology to simulate a three-dimensional virtual world, allowing users to perceive things in the virtual space in a timely and unlimited manner. At present, in order to obtain the spatial position of VR devices such as VR headsets and handles in real time in the VR game experience, many VR experience games use the mode of binding the user to a special fixed seat or platform, and use the VR spatial positioning technology to real-time Get the spatial position of the VR device. VR space positioning technology is a key technology in the VR field. It can locate the real-time position of VR devices such as VR headsets ...
