Application of 3D scanning technology in fire investigation
Among the firefighters, with the exception of the Fire Heroes,
There is also a special group.
They, sifting through the rubble for evidence,
Find out the truth in the ashes.
They are known as "Fire Holmes".
They are——fire investigators.
Challenges of fire investigation
When everything at the fire site is covered with dust and blackened by fireworks, the physical evidence information of structural damage, critical debris and complex features of the building should be obtained in the shortest possible time. This is a complex and challenging task for fire investigators.
However, traditional methods such as image acquisition by SLR camera and manual measurement are not applicable, which is dangerous and time-consuming.
Advanced technology, convenient and easy to operate equipment, digital solutions are essential in fire investigation.
Application of FARO 3D laser scanner in fire investigation
Fire investigators knew the scene was extremely unsafe after the blaze. The toxic fumes and substances may still be there, and the scene may be dark and damp, and not completely calm. Precise measurements come in handy when seconds count. All evidence can be accurately captured as soon as possible, limiting the contact between evidence and personnel, and avoiding evidence contamination.
FARO 3D laser scanners are the sketchpad for fire investigators. FARO laser scanners allow investigators to capture all details even under the most extreme field conditions. Through the method of high speed laser scanning measurement, it helps fire control personnel to quickly acquire a large number of THREE-DIMENSIONAL information data of fire scene, for investigators to quickly recover the scene, establish three-dimensional model, and generate charts and reports required for court testimony.
The solution 01 Field Modeling
FARO Focus Laser scanners create accurate, comprehensive and realistic THREE-DIMENSIONAL images of any environment or object in just a few minutes. Moreover, the FARO Focus laser scanner is as easy to operate as a digital camera with an intuitive touch screen and compact design, and has built-in anti-fouling, dust, fog, rain and heat/cold features.
Through the FARO Focus laser scanner, fire investigators can collect the data information of the fire scene in a very short time, record the indoor and outdoor conditions of the fire scene, and prevent the subsequent destruction of the scene, resulting in the damage of key material evidence.
02 Data Processing
Using FARO SCENE software, fire investigation staff can easily and efficiently process and manage the scanned data, such as data noise reduction, splicing, etc., create excellent 3D visualization effects, and output internal modeling point cloud model files (RCS format or RCP format). In addition, the 3D restoration of the fire site can be carried out in panoramic view, 3D overlook roaming view and virtual reality view for permanent site preservation.
03 Animation roaming
When a fire occurs, fire investigators must establish the facts and thoroughly document the case. This process is critical to fire investigations. FARO Zone 3D software is an indispensable tool. Based on this software, 3D model files and internal and external roaming animation videos can be made.
FARO Zone 3D makes it easy to accurately analyze fire incidents and generate detailed visuals, such as accurate 2D and 3D charts, persuasive animations, and reports for use in court. The software also has an immersive virtual reality feature that allows viewers to experience the scene of a fire in an unprecedented way.
It's about truth, it's about life, and we have to use the right tools. FARO 3D laser scanners and FARO Zone 3D software make fire investigators' work more efficient and intelligent.
