Embodiment 1

[0063] Such as figure 1 As shown, a virtual reality-based crowd simulation system includes: a virtual reality scene building module, a building and obstacle model library, a character library, a real person database, a character model library with physical differences, a character attribute library, Test modules and evaluation modules.

[0064] Building and obstacle model library: contains a large number of building models and obstacle models. The building and obstacle model library is not limited to the building itself as a complete building, but also includes various facilities in the building, etc. The building models in this module can be enriched and added through manual modeling, physical scanning, etc. , can be any building model, obstacle model, etc. that already exists in the real world or can be conceived. Through the rich building model library, various physical environments required in crowd simulation can be met.

[0065] Real person database: Contains a large n...

Embodiment 2

[0096] The invention also provides a crowd simulation database. After the system is in operation, the system's building and obstacle model library, real person database, character model library with physical differences, character attribute library, character role library, virtual reality scenarios, system evaluation and other modules will collect a large number of The data and information about the crowd simulation, and with the growth of the system operation time, the database of the system will become very rich and powerful, thus providing a rich database for the crowd simulation in the future.

Abstract

The invention discloses a virtual reality based crowd simulation method and system. The method includes: step (1), establishing a building and obstacle model library; step (2), respectively establishing a real person database, a model database of people with physique differences and a character attribute library; step (3), establishing a character library according to results of the step (2); step(4), establishing a virtual reality scene according to results of the step (1) and the step (3); step (5), testing the virtual reality scene; evaluating a test result, and outputting an evaluating result. By combination of person models and character attributes, various characters can be created; in addition, the real person database enables direct use of real person mapping which includes various attributes of real persons; moreover, due to real person control of the system, crowd diversity in crowd simulation is further improved.

Description

technical field [0001] The invention relates to the technical field of crowd simulation, in particular to a crowd simulation method and system based on virtual reality. Background technique [0002] With the development of society and the progress of human beings, the number of population is also increasing, and the probability of people traveling in various public places is getting higher and higher. Encountering congestion is also a frequent occurrence. Places with many people are prone to various question. Nowadays, people's demand for crowd simulation is getting higher and higher, and with the improvement of hardware level, everyone's demand for crowd simulation with high simulation degree, high authenticity and high diversity is also getting higher and higher. [0003] Virtual reality technology is a combination of simulation technology, computer graphics, multimedia technology and other technologies. It is an emerging digital human-machine interface. The emergence of...
