A crime scene or accident site exists for only a short time before it must be cleared. 3D laser scanning lets investigators preserve it digitally — accurately and permanently.
What a 3D scan captures
A laser scanner rapidly measures the geometry of a space, building a dense "point cloud" — a precise digital model made of a very large number of measured points, often combined with photographic colour. The result is a measurable, navigable 3D record of the scene exactly as it was found.
Why it helps investigators
- Speed at the scene: large areas can be documented far faster than with manual measurement.
- Accuracy and completeness: the scan captures detail that may not seem important at the time but proves critical later.
- Revisit any time: investigators and courts can "walk through" the scene long after it has been cleared.
- Clear presentation: 3D models and measured diagrams communicate findings effectively in court.
Where it fits
Beyond crime scenes, the same technology supports road-accident reconstruction, fire and blast investigation, and facility documentation. It is increasingly a standard tool for forensic science laboratories and investigation units that need defensible, reusable records.
