Problems solved by technology

Although there are many systems and models for crowd simulation, there are still many problems in crowd simulation, such as the lack of simulation systems with high simulation degree, high authenticity and high diversity, such as low authenticity and lack of crowd diversity.
At present, it still cannot meet people's needs for high-fidelity systems.

Embodiment 1

[0074] Such as figure 1 As shown, a crowd simulation system based on virtual reality, the system includes a virtual reality scenario module, a building model library module, a virtual character library module, a character voice and environmental sound collection library module, a collision visual blur module, and has a high degree of simulation Character library module, real person database module, character model module with physical differences, character attribute library module, tester module, virtual reality equipment module and system evaluation and detection module.

[0075] Building and obstacle model library module: 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...

Embodiment 2

[0108] The invention also provides a crowd simulation database. After the system is in operation, the system's building and obstacle model library, character sound and environmental sound collection library, real character database, character model library with physical differences, character attribute library, and character library with high simulation , virtual reality scenarios, system evaluation and other modules will collect a large amount of data and information about crowd simulation, and with the growth of the system operation time, the database of the system will become very rich and powerful, thus providing abundant information for future crowd simulation. database.

Abstract

The invention discloses a virtual reality crowd simulation method and system based on avoiding the uncanny valley effect, including avoiding the "uncanny valley" effect in vision and the "uncanny valley" effect in touch. In terms of avoiding the visual "uncanny valley", a virtual character library module is added. In terms of avoiding the tactile "uncanny valley", a character sound and environmental sound collection library module and a collision visual blur module are added to effectively reduce and avoid the visual and tactile "uncanny valley". "The discomfort and loss of immersion brought to people, thus making the crowd simulation more human-like and natural, more immersive and more authentic.

Description

technical field [0001] The invention relates to a virtual reality crowd simulation method and system based on avoiding the uncanny valley effect. 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. At present, the society's demand for crowd simulation is increasing, especially for crowd simulation with high simulation degree, high crowd diversity, high authenticity, high interactivity, and high computing efficiency. Now the crowd simulation is relatively real and impressive. . [0003] Virtual reality technology is an emerging digital human-machine interface. After the outbreak of virtual reality in the first year of virtual reality, new technologies and new devices continue to appear...
