AI Technical Summary

Technical Problem

Existing simulation methods for human movement, such as Social Force Models (SFM) and cellular automata, struggle with computational intensity and inaccuracies when obstacles are present on the direct path to a destination, as they fail to account for alternative routes.

Method used

A simulation device and method that utilizes pre-generated potential fields for different types of information, synthesizing a composite potential field to determine movement directions, reducing computational load while maintaining high precision by using asynchronous processing and pre-generated fields for building, sensor, and virtual object data.

Benefits of technology

Achieves high-precision simulation of multiple moving objects with reduced computational load by using pre-generated potential fields, allowing for efficient simulation of large areas like buildings and optimizing equipment control.

Abstract

This system achieves both high-precision simulation and reduced computational load for the movement of multiple moving objects within a defined area. [Solution] The simulation device includes: a potential field creation unit that performs a simulation of the movement of a moving object in a predetermined region and creates a potential field having a potential value indicating the difficulty of movement for the moving object at each point, using two or more different potential fields for each type of information used; a composite potential field creation unit that synthesizes a composite potential field using a group of potential fields consisting of multiple potential fields; a movement direction determination unit that determines the movement direction of each moving object based on the composite potential field and the position and destination of each moving object; and a simulation execution unit that performs a simulation for each moving object based on the movement direction.
