Abstract

The invention discloses a route planning-based crowd evacuation simulation method and system. The method comprises the following steps of: creating an evacuation scene three-dimensional model, creating a three-dimensional figure model, and importing the three-dimensional figure model into the evacuation scene three-dimensional model; dividing a to-be-evacuated crowd into a plurality of groups according to positions of individuals and distances between adjacent individuals, and selecting a leader for each group; establishing a one-to-one mapping relationship between each parameter of crowd evacuation and each parameter of an artificial bee colony algorithm; carrying out macro route planning by adoption of the artificial bee colony algorithm, and searching a route, from an initial point to atarget point, of each individual; and carrying out micro crowd movement guidance by adoption of a social force model, and generating a collision-free crowd evacuation simulation movement. The methodis capable of realizing large-scale crowd evacuation simulation under different scenes.

Description

technical field [0001] The invention relates to the field of crowd evacuation simulation, in particular to a method and system for crowd evacuation simulation based on path planning. Background technique [0002] In social life, fires, earthquakes, and stampede incidents occur frequently, and untimely evacuation will cause a large number of casualties and property losses. In-depth research on crowd evacuation has great practical significance and practical value. Traditional crowd evacuation drills are not only time-consuming and labor-intensive, but also may cause casualties, so crowd animation simulation has become a popular direction for crowd evacuation research. Through the simulation of the real scene, not only can the real scene be observed quickly and easily, but also better suggestions can be made for crowd evacuation. [0003] The artificial bee colony algorithm (artificial bee colony, ABC) was proposed by D. Karaboga in 2005 by applying the foraging behavior of be...
