We offer the following services:
Laser scanning – Laser scanning is quickly becoming an area popular by crime scene investigators and accident reconstructionists to quickly and accurately document a crime or accident scene quickly and with great detail. Laser scanners can pick up millions of points in just seconds providing a vast amount of data. However, working with point cloud data can be complex and cumbersome and the question always arises as to how to implement a point cloud into an animated 3D recreation of a scene? We are able to use point cloud data in our 3D visualizations and use the point cloud environments as the foundation of our scene models for shooting reconstructions, crime scenes, vehicle accidents and much more.
We also provide on and off scene small to medium scanning services to assist investigators in documenting other forms of evidence such as shoe tread patterns, footprints, tire prints, bone and bone fragments, toolmarks, suspect and victim clothing and much more. The generated models are sub millimeter accuracy (thousandths of an inch) and can be used to provide 3D measurements in pattern matching and comparison analyses.
Total Station Mapping – Forensic mapping is different from regular surveying since there are different aspects of documenting evidence that are normally not required in a regular land survey. Understanding how the evidence needs to be documented has impacts further down in a forensic investigation and often, you only get once chance at good data! The data that is captured can be used to create 3D models of an environment or positions of evidence with respect to one another. These can all be incorporated into a shooting reconstruction, vehicle accident animation and other 3D visualizations.
Photogrammetry – Photogrammetry has two main functions. The first is to be able to use your digital camera as a precise measuring instrument, just as you would a laser scanner or a total station. Photogrammetry is especially useful on complicated organic surfaces that can not be reached or would be very difficult or more complex to measure by hand (e.g. Bloodstains, bullet trajectories, crush measurements on a vehicle…etc.). The second and perhaps most useful use of photogrammetry is that you can get measurements from photographs that were taken at a crime or accident scene by another person or with security video. There are some basic requirements to this technique, but in many instances, valuable informaiton that would otherwise be lost, is obtainable.
3D Forensic Reconstructions & Visualizations
Forensic reconstructions and visualizations continue to be a growing area for expert witnesses, lawyers, investigators and accident reconstrutionists for analyzing and visualizing a scene or event. The areas of application extend from shooting reconstructions, vehicle accidents, medical animations and even lesser known areas such as data visualization.
Forensic Virtual Models (FVMs):
Forensic Virutal Models are the next generation of forensic animations in that they allow the user to control the perspective and movements of the scene. FVMs are a bridge between an animation and true virtual reality without the need for complex suits, glasses and interactive devices. Everything can be controlled from you PC to trigger predetermiend movements, camera positions and even hyperlinks. These are especially useful for courtroom presentations or for expert witness testimony to complex cases or scenarios where events are better provided visually and in full 3D without the contraint of just one view.
