Abstract

The invention discloses a crowd evacuation simulation method and a crowd evacuation simulation device, which can provide evacuation path guidance for crowds, prevent falling into local optimum and improve evacuation efficiency. The crowd evacuation simulation method comprises the following steps: obtaining a crowd image, and preprocessing the crowd image; Extracting texture features of the crowd image; Estimating and classifying the crowd density by utilizing an extreme learning machine algorithm according to the texture features of the crowd image to obtain a crowd density level; and according to the crowd density grade, simulating the crowd image by utilizing an artificial fish swarm algorithm to obtain an optimal evacuation path.

Description

technical field [0001] The disclosure belongs to the field of crowd evacuation simulation, in particular to a crowd evacuation simulation method and device based on the combination of artificial fish swarm algorithm and extreme learning machine algorithm. Background technique [0002] With the rapid development of the economy, people's leisure life is becoming more and more abundant. Large-scale crowds often gather in public places, and the safety hazards caused by overcrowding are becoming more and more serious. In order to avoid congestion events and reduce the loss of life and property, computer simulation technology is used for scene modeling, path optimization and crowd movement behavior modeling, which can minimize the cost while achieving the best evacuation drill effect. Therefore, computer simulation has become the most important method to study crowd evacuation under emergencies. [0003] Extreme learning machine (extreme learning machine, ELM) is a kind of machin...
