A virtual reality roaming system and method based on improved redirection walking

Abstract

The invention provides a virtual reality roaming system and method based on improved redirection walking, and the method comprises the steps: inputting a virtual space plane graph, and employing a skeleton graph generation algorithm based on a Voronoi graph to calculate a feasible skeleton graph of a user in a virtual space in advance; according to the skeleton map in the virtual space, establishing a mapping relation between the user feasible skeleton map in the virtual space and the user feasible skeleton map in the physical space by using a static skeleton map mapping algorithm; tracking the spatial position and direction of the user in the physical space in real time through the input module; and according to the established mapping relationship between the virtual space and the physical space, calculating the corresponding spatial position and direction of the user in the virtual space in real time by using a position inverse mapping algorithm and a curvature gain redirection technology, and generating a corresponding user view image through a rendering module.

Description

technical field [0001] The present disclosure relates to a virtual reality roaming system and method based on improved redirection walking. Background technique [0002] Virtual reality technology integrates computer graphics, machine vision, artificial intelligence and other information technologies from a higher level, presents virtual information in a three-dimensional simulation way, gives users the ability to interact in the three-dimensional virtual world, and realizes users' immersive observation Even control the purpose of scene information. Among them, an extremely important interactive content in virtual reality technology is how the user moves in the virtual space. Traditional virtual reality systems mostly use hand-held controllers (such as keyboards, mice or handles) or mechanical auxiliary devices (such as virtual treadmills) to move users in the virtual space. Among them, the mechanical auxiliary device uses the mechanism of relative motion to keep the user ...

AI Technical Summary

Problems solved by technology

[0003] 1) The hand-held controller only realizes the user's visual spatial movement, and the user is still in a static state. There is a deviation between this virtual motion state and the actual cognition of the brain, which will cause some users to experience dizziness and discomfort during the experience;

[0004] 2) Mechanical auxiliary devices have high requirements on hardware equipment, requiring extremely high equipment precision and response speed

However, the current mechanical auxiliary device is not enough to achieve complete synchronization with the user, so it cannot truly restore the natural somatosensory walking ability, and the user experience is very limited;

[0005] 3) Although spatial positioning technology can provide users with a real and natural walking experience, it can only realize free walking in a virtual space of the same size as the physical space due to factors such as the scannable range of the locator and the size of the physical space. The design of the virtual space will cause great restrictions, and cannot provide a complete real walking experience in a large-scale virtual space
