3D Scanning
3D scanning is a vital tool in Forensic Sciences, allowing for a digital or physical representation of an environment, object, scene, or event that is much easier for viewers to process and use than the actual subject. Moreover, three-dimensional data is the primary prerequisite of creating high quality simulations, animations, scaled diagrams, and models.
Our Lab utilizes multiple enterprise-level 3D LiDAR scanners to provide accurate and detailed scans. In conjunction with sophisticated rendering software and 3D scale modeling hardware, our engineers provide the highest quality scans and physical models for your case.
Below is a raw scan of a crash scene from a hit and run case.
What is LiDAR?
LiDAR scanners provide very precise mappings of their environments. First, the laser scanner emits a laser beam from a rotating mirror out towards the area being scanned. Then, the unit distributes the laser beam to a vertical range of 300° and a horizontal range of 360°. The laser beam is then reflected to the scanner by the object in its path. The distance to the object defining an area is calculated as well as the relative vertical and horizontal angles. The data is captured and transmitted via WLAN for calculating exact 3D renderings.
The Forensic Scientists at IRSA are all trained in the proper operation of the 3D scanner.
3D Modeling
A 3D Model is a scaled representation of a scene, which can be a vital visual tool in showing how an accident happened. These models may be digital, as seen above, or physical, as discussed below.
By using a physical model, one can maneuver and manipulate a person, car, or other subject that is pertinent to the incident.
The 3D model of a site, subject, or accident scene is created and mirrored by reviewing case pictures, performing a physical inspection, and/or utilizing 3D Scan software.
The model components are designed, built, sourced, and/or 3D printed directly by IRSA engineers.
The application of physical models include depositions, arbitrations, and trials. We thoroughly discuss how the model was built, how it works, and the best most of transporting the display.
