Advanced Fire Investigation Technique Utilizing Virtual Reality

Abstract

This paper presents an advanced technique for fire investigation via the development and application of a virtual reality (VR)-based system. After capturing a fire scene with a 360° camera, the acquired image files are processed, edited, and executed through a developed program to reconstruct the scene in VR. Currently, fire investigation methods involve writing reports based on photographed pictures. However, this 2D approach has limitations, as individuals who cannot visit the site in person lack a sense of presence and immersion. When the proposed technique is applied to scene investigations, wearing an head-mounted display allows for the investigation of scenes from a 360° 3D perspective that maximizes vivacity and immersion. This technology facilitates collaboration with experts from various fields who could not otherwise participate in a scene, thereby enabling the reliable derivation of fire causes. Additionally, the proposed method allows for the 3D digital preservation of major national disaster incidents and can therefore convey lessons from accidents to future generations. In the future, the proposed VR reconstruction system could be utilized as valid evidence in court cases.
