Actual and virtual space mapping method and system suitable for virtual roaming system

Abstract

The invention provides an actual and virtual space mapping method and system suitable for a virtual roaming system, and the method comprises the steps: extracting a two-dimensional plane graph of a given virtual roaming scene, and building a Voronoi graph for the two-dimensional plane graph; establishing a skeleton path according to the established Voronoi diagram; generating a corresponding skeleton roaming path according to the input starting point of the roaming path, and merging the paths to obtain the roaming path; mapping the roaming path in the virtual scene into an actual walking pathin an actual space; obtaining the spatial position and direction, tracked in real time, of the user in the physical space in the walking process along the actual walking path, and calculating the corresponding spatial position and direction of the user in the virtual space in real time through a position inverse mapping algorithm for image rendering. The user can be effectively guided to be away from the boundary of the tracking area, the user resetting frequency of the system is greatly reduced, pause feeling is reduced, and immersion of the user is enhanced.

Description

technical field [0001] The disclosure belongs to the technical field of virtual reality, and relates to a method and system for mapping real and virtual spaces suitable for a virtual roaming system. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] Virtual reality technology (Virtual Reality, abbreviated as VR) is a new practical technology developed in the 20th century. This technology integrates computer, electronic information, and simulation technologies, and simulates the virtual environment through the computer to give people a sense of environmental immersion. With the continuous development of social productivity and science and technology, all walks of life have a growing demand for VR technology, especially immersive virtual reality. This technology has a wide range of applications in education, data visualization, real estate, t...

AI Technical Summary

Problems solved by technology

Although such a path planning strategy brings freedom of roaming, when the virtual scene area is large (such as a campus, a natural park, or a geographical administrative area), it is difficult for users to roam efficiently and immerse themselves in the environment. One of the biggest limitations of the current roaming system is that users cannot stay in this environment for a long time. When it exceeds 20 minutes, most users will feel obvious dizziness

Therefore, the path planning of random walk is obviously not suitable for the needs of users to visit larger virtual scenes.
