AI Technical Summary

Technical Problem

Existing technologies cannot simulate real smoke diffusion conditions in a fire, resulting in insufficient realism and controllability in personnel evacuation experiments, which affects the accuracy and reliability of experimental data.

Method used

By constructing a smoke-visual equivalent model, fire smoke data is mapped into visual information. A highly realistic dynamic fire smoke virtual scene is generated using a virtual reality engine and particle system, and registered with the actual physical space. Experiments are conducted using mixed reality equipment to capture the three-dimensional motion trajectory and posture data of personnel in real time for data processing and analysis.

Benefits of technology

It achieved a highly realistic fire smoke experimental environment, obtained key data, improved the reliability of experimental data, and provided research support for the influence mechanism of fire smoke parameters on evacuation behavior.
