Abstract
An improvised explosive device (IED) is a “homemade” bomb intended to cause great harm when it explodes. The public safety task of identifying and neutralizing IEDs falls to military and police services often called explosive disposal units (EDU) who act to neutralize the threat associated with the IED either rendering it inoperable or destroying it safely. EDUs train in various aspects of explosive handling and investigation but are limited in the tools available for safely analyzing real world bombs. This paper describes a game based approach to IED training that employs an interactive 3D simulation to spatially identify key IED components of interest. We give an example of how this approach might be used and provide a preliminary evaluation of its potential effectiveness. We employ images formed from a Digital Imaging and Communications in Medicine (DICOM) system captured using Magnetic Resonance Imaging (MRI) technology to a virtual IED in a game. Empirical evaluation and EDU testimony suggest accurate representation of the IED and the potential efficacy of the proposed approach for successfully identifying components in the bomb for the purposes of EDU training.
Highlights
Introduction and BackgroundAn improvised explosive device (IED) is a “homemade” destructive device designed to destroy, incapacitate, harass, or distract [1]
Stemming from this work, we present an approach to separate parts of an IED within a model and provide a game-based simulation that can potentially assist in the training of explosive disposal units (EDU) personnel with the benefits of lowering exposure to actual IEDs, and providing visually and spatially accurate 3D model representations
The motivation for our methodology has been to set the stage for safe investigation of IEDs for EDU professionals
Summary
An improvised explosive device (IED) is a “homemade” destructive device designed to destroy, incapacitate, harass, or distract [1]. Many commonly available materials such as fertilizer and common chemicals can be used as explosive materials in IEDs. Many commonly available materials such as fertilizer and common chemicals can be used as explosive materials in IEDs They can be constructed in many forms, ranging in size and power from small and simple pipe bombs causing severe injuries to a few people to large and sophisticated devices capable of causing massive damage and loss of life. Chemicals for explosives, and materials and products that can be modified to function as casings, shrapnel, triggering mechanisms and power sources have become readily available on a large scale. The potential number, variety and complexity of IED designs can make it difficult for EDU personnel to safely investigate a bomb’s characteristics and effectively neutralize its threat without endangering themselves
