Problems solved by technology

[0006] 1) For most users, the tracking devices and areas they provide for the virtual reality environment may be much smaller, so there will be space limitations, and users will face many wall collisions and reset problems, so Users experience severe pauses during roaming navigation
[0007] 2) In RDW, the traditional steering algorithm is to guide the user to walk towards the center of the area or certain target points in the tracking area, and the result is that the user will appear at a certain point in the actual space with a higher frequency. In some points or areas, such as the central point position in the actual space; in this case, the method is difficult to satisfy the situation of multiple people roaming at the same time, and collisions between users will inevitably occur

Embodiment 1

[0058] Such as figure 1 As shown, Embodiment 1 of the present invention provides a method for mapping actual and virtual spaces suitable for a virtual roaming system, including:

[0059] Step (1): Given a virtual roaming scene, establish a Voronoi diagram; establish a skeleton path according to the Voronoi diagram; generate a corresponding skeleton roaming path according to the user's choice, and merge the paths to obtain a roaming path;

[0060] Step (2): Decompose the roaming path VPath in the virtual scene into K segments according to the divide-and-conquer strategy;

[0061] Step (3): The segmented virtual path is sequentially mapped to a Bézier curve with the goal of minimizing the internal energy;

[0062] Step (4): Connect adjacent curves into continuous smooth curves through smooth constraints to obtain the walking path in the actual space.

[0063] Step (5): The user walks along the actual path mapped in step (4).

[0064] In step (1), the process of establishing a...

Abstract

The invention provides a mapping method and system suitable for large-scale virtual reality redirection walking. The mapping method comprises the following steps of acquiring virtual roaming scene data, obtaining a roaming path according to the obtained virtual roaming scene data, decomposing a roaming path in the virtual scene into a plurality of segments, sequentially mapping the segmented virtual paths into Bezier curves by taking minimization of internal energy as a target, according to a preset smooth constraint condition, connecting adjacent curves into a continuous smooth curve, and obtaining a walking path in an actual space. According to the method, the user can be effectively guided to be far away from the boundary of the tracking area, the number of times of resetting the user by the system is greatly reduced, the navigation speed and smoothness are effectively improved, the pause feeling and perception distortion are reduced, and the immersion feeling of the user is enhanced.

Description

technical field [0001] The invention relates to the technical field of virtual reality, in particular to a mapping method and system suitable for large-scale virtual reality redirected walking. Background technique [0002] The statements in this section merely provide background art related to the present invention and do not necessarily constitute prior art. [0003] The concept of VR (Virtual Reality, virtual reality) was proposed in the 1980s. With the development of computer technology, especially the development of high-performance computing, computer graphics and human-computer interaction technology, human beings have achieved the goal of simulating the real world. latest state of affairs. In contemporary VR technology, virtual roaming technology has become one of the current VR research hotspots, and its research purpose is how to allow users to move naturally in the virtual world and explore a larger virtual space in a limited physical space. In order to solve th...
