3D scanning technology for law enforcement and public safety
3D scanning technology for law enforcement and public safetyLast Edited: 10/07/2017
3D laser scanning has come on in leaps and bounds in the last decade. It is now possible to produce an incredibly detailed photograph of a shell casing's headstamp, which demonstrates the calibre of the round. This is far more accurate than measuring by hand and produces far better results. And this is but one example of the ways in which 3D scanning technology can be used by law enforcement to enhance public safety.
3D visualisation is now capable of recreating crime scenes, making it possible to give a person the perspective of various different individuals who were involved in a crime. This function is not only invaluable to law enforcement officers at determining what happened at a particular crime scene, it is also greatly beneficial to the justice process, and ensuring that the guilty are prosecuted, while the innocent are exonerated. 3D visualisation allows cases to be tried from the perspective of the victim, and the perpetrator(s) of the crime, as well as allowing them to walk around the scene and get a really clear idea of what happened.
Law enforcement has been increasingly relying on camera and photography technology for years to aid them in their work. From traffic cameras to mug shots, video surveillance to body cameras, and the ability to easily document, record, and recreate an incident, technology is now a central aspect of the mission of law enforcement officers to ensure public safety.
While 3D scanning technology may seem futuristic, in many ways it is the next natural evolutionary step for photo technology. Video evolved from photography, giving us moving pictures in addition to stills. 3D laser scanning engineering is now allowing us to take this one step further, and create a three-dimensional image. We've evolved from the two-dimensional static image to two-dimensional moving images, and we now have three-dimensional image capabilities.
The 3D scanners most frequently used by law enforcement are generally high-end devices, placed upon a tripod. Such machines have a max instantaneous scanning speed of around 50,000 pps (points per second). Specialist software manages 3D documentation, and allows users to transmit and manipulate images using a computer or tablet.
Handheld tablets allow investigators to easily verify they have successfully scanned a whole scene before leaving.
But there are 3D scanners at consumer-level being utilised by law enforcement to enhance public safety also. Such devices include 3D desktop scanners that are capable of recreating dental moulds, and accessories that work with smartphones, providing easily portable 3D scanning capabilities. Such technologies are well on their way to revolutionising the manner in which evidence is gathered, and the effectiveness of utilising information captured by citizens using their own smartphones.
At PointSCAN, we know 3D scanning technology will continue to evolve and grow, and law enforcement will go on finding new and inventive ways to utilise it in their efforts to enhance public safety.
