Embodiment Construction

[0034] Certain terms are used, for example, in the description and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. As mentioned throughout the specification and claims, "comprising" is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect. In addition, the term "coupled" herein includes any direct and indirect electrical coupling means. Therefore, if it is described that a first device is coupled to a second device, it means that the first device may be directly elect...

Abstract

The invention discloses a virtual reality roaming process collision detection optimization design method and a system thereof. The method comprises the steps of identifying the appearances of all structures and parts on a roaming plane in a virtual reality scene and extracting the projection profile of the appearances of the structures and parts on a scene ground, fitting the extracted projection profile of the appearances of the structures and parts as a polygon shape of a profile edge, and generating a transparent collision surface which is perpendicular to the scene ground according to the polygon shape after fitting. According to the method and the system, a problem that a user can not walk out of a dead corner after entering into the dead corner in virtual reality roaming and the amount of computation is increased caused by nearness to a scene detail in the prior art is solved.

Description

technical field [0001] The present application relates to the field of digital image processing, in particular, to a method and system for collision detection optimization design in virtual reality roaming process. Background technique [0002] Virtual reality (Virtual Reality, referred to as VR) is a high-tech that has emerged in recent years, also known as spiritual technology or artificial environment. Virtual reality is to use computer simulation to generate a three-dimensional virtual world, providing users with simulations of vision, hearing, touch and other senses, allowing users to observe things in three-dimensional space in a timely and unrestricted manner as if they were actually there. This process is called virtual reality tour. At present, virtual reality technology is widely used in many fields such as urban planning, military simulation, geography and industry. [0003] In the existing technology, the simulation system can simulate the scene in the industri...
