Embodiment Construction

[0052] In order to better understand the purpose, structure and function of the present invention, a method for simulating the motion of a multi-emotional crowd based on a fractional potential field model of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0053] Such as figure 1 , figure 2 As shown, the multi-emotional crowd motion simulation method based on the fractional potential field model of the present invention comprises the following steps:

[0054] Step 1: Divide the crowd according to their different emotional states during exercise, such as image 3As shown, the emotional state is divided into four states: Calm, Anxiety, Panic, and Hysteria. At the same time, the anxiety degree range is divided for pedestrians in different emotional states, and the maximum expected speed and range of sight are set for pedestrians in different emotional states. Combined with the actual situation, we can get Schemati...

Abstract

The invention belongs to the field of crowd modeling and simulation, and discloses a multi-emotion crowd motion simulation method based on a fractional order potential field model. According to the method, individual emotional states are divided into Calm, Anxiity, Panic and Hysteria according to different emotional states generated by factors such as environment in the movement process of pedestrians, corresponding vision field ranges are divided for the different emotional states, and a fractional order potential field model is redefined as an emotional field conforming to the movement law of people; according to the areas, the motion states and the emotional states of other individuals, the emotion acting force between the individuals is obtained, and interaction behaviors between the individuals and the environment and other individuals are simulated through the Newton's second law. The method can effectively simulate the mutual influence between individuals and surrounding individuals under the emotional effect, pedestrians in different emotional states present different interaction forms in the evacuation process, and the method has the advantages of novelty, simplicity, easiness in understanding and simplicity, convenience and effectiveness in operation.

Description

technical field [0001] The invention belongs to the field of crowd modeling and simulation, and in particular relates to a motion simulation method for multi-emotional crowds based on a fractional potential field model. Background technique [0002] Crowd motion modeling and simulation is a research hotspot in computer graphics, safety science, and artificial intelligence, and has been used in many application areas, such as crowd evacuation, digital entertainment, and social security. Crowd simulation can well reproduce the self-organization phenomenon of crowd movement, and at the same time combine various uncertain factors such as individual physiological characteristics and social factors, it can more accurately simulate the evacuation behavior of crowds in emergency situations. [0003] Emergency situations in real life often cause pedestrians to be nervous. And these negative emotions can easily spread among the crowd, which may eventually lead to large-scale crowd di...
