Abstract

The invention discloses a crowd motion simulation method and system. The method is completed in a simulation server and the specific process comprises the following steps: receiving a scene model and crowd individual information, and respectively initializing the scene and the crowd individual information; performing grouping by using the K-Medoids algorithm with multiple influence factors according to the distances and relationships among individuals in the crowd to obtain a grouping condition of the crowd; and using the grouping condition of the crowd as an initial state of crowd motion, performing local path planning by using a companion group model based on affinity to realize group behaviors and collision prevention, and figuring out the motion path of each individual to arrive at a selected exit; and rendering the motion path and displaying a simulation result in real time.

Description

technical field [0001] The invention belongs to the field of crowd simulation, and in particular relates to a crowd motion simulation method and system. Background technique [0002] In large public places with dense crowds, such as: squares, campuses, shopping malls, etc., accidents of crowding and stampede accidents causing casualties are becoming more and more frequent, and the safety of personnel is prominent. The reasons for analyzing such problems mainly include: [0003] (1) Before the accident, there was no investigation of possible hidden dangers in the venue, and no prediction of the possible crowding of the crowd; [0004] (2) No scientific and effective evacuation guidance behavior was adopted for the crowd after the accident. Such public safety issues caused panic among the people, caused a lot of property damage, and seriously interfered with the pace of urban development. [0005] Using computer simulation technology to simulate the group behavior of the re...
