Embodiment Construction

[0042] The technical solution of the invention is further described below in conjunction with specific embodiments.

[0043] Crowd behavior simulation method based on grid agent:

[0044] Step 1: grid data processing;

[0045] A grid can be defined as a 2.5D grid unit with a fixed regular size that corresponds to a spatial position and can express semantic information. Mathematically, Grid can be expressed as

[0046] Grid=(G g ,G p )

[0047] where G g is the geometric description of the grid, G p A list of attributes for the grid.

[0048] In the grid agent model, the grid will be used as the basic spatial unit associated with "people" and "land", that is, on the basis of the grid, the spatial position, the object of the ground and the relationship between the objects of the ground will be described; while the individual The spatial area occupied at a certain moment is a single or several grids, and the individual's perception of ground objects will also be defined b...

Abstract

The invention discloses a crowd behavior simulation method based on a grid agent. The crowd behavior simulation method comprises the following steps: step 1, grid data processing, wherein input data of the grid data processing are three-dimensional model data and a ground object topological relation, output data are grid object information, and the grid data processing comprises three sub-steps: 1, definition of a grid object; 2, searching and setting of a boundary grid; and 3, defining a topological connection relation of the grid object; step 2, crowd behavior calculation: the main function of the crowd behavior calculation is to provide the crowd behavior calculation with an individual as a unit, wherein input data are crowd behavior parameters and the grid object information obtained in step 1, output data are crowd behavior information, and the crowd behavior calculation comprises two sub-steps: 1, setting the crowd behavior parameters; and 2, calculating a crowd behavior trace; and step 3, crowd simulation visualization, wherein the main function of the step is to realize the visualization of the geographical environment and human behaviors.

Description

technical field [0001] The invention belongs to the technical field of crowd behavior simulation, and in particular relates to a crowd behavior simulation method based on a grid agent. Background technique [0002] Crowd behavior simulation is to study the behavior characteristics and laws of crowds in various scenarios, establish a simulation model of crowd behavior, and display the simulation process of crowd behavior realistically in a virtual environment. With the development of computer simulation technology, especially the rapid development of digital human behavior simulation technology, crowd behavior simulation technology in virtual environment has become an important research focus of virtual reality technology. Crowd behavior simulation technology is not only widely used in building design, modern film and television entertainment media, computer games, national defense research and other fields, but also in crowd evacuation simulation in emergency situations, mil...
