Problems solved by technology

[0004] When performing crowd simulation, since most crowd simulation systems cannot simulate crowd attention, there is a lack of data collection and research on crowd simulation attention
Sometimes the attention of the crowd also plays an important role, but it is often difficult to obtain, especially in the event of an emergency

Abstract

The invention discloses a virtual reality crowd simulation method and system based on eye movement tracking. A crowd simulation database is established, which comprises a building and obstacle model database, a human voice and environment sound collection database, a real human database, a human model database and a human attribute database. The virtual reality scene is constructed by selecting building and obstacle models from the building and obstacle model database and combining with the human voice and environment sound collection database. Based on the real character database, the human model database and the human attribute database, the virtual human with high simulation degree is constructed and placed in the virtual reality scene. According to the route planning of crowd escape orevacuation in emergencies, the virtual human is simulated and the eye movement tracking data is collected in simulation. The eye movement tracking data is labeled on the surface of the building modelto determine whether the locations of safety signs in the building are reasonable or not. The invention is helpful to improve the efficiency of crowd escape and evacuation in emergencies such as disasters.

Description

technical field [0001] The invention relates to the field of crowd simulation, in particular to a virtual reality crowd simulation method and system based on eye movement tracking. Background technique [0002] With the development of society, the progress of human beings, and the continuous increase of the population, the probability of people traveling in various public places is also 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 a new digital human-machine interface. Shorten th...
