Common questions
How does an AR walk-through differ from a 3D laser scan of a scene?+
A laser scan produces a static point-cloud model of the scene captured once, while an AR walk-through overlays live annotations onto a real-time or recorded view, letting an investigator or remote reviewer see measurements and notes anchored to the actual space as they move through it.
What is the practical benefit of an AR walk-through for a case that goes to trial?+
It lets attorneys, experts, or jurors who were not at the original scene revisit annotated evidence positions and spatial relationships without needing specialist scene-reconstruction software, though the underlying capture must still be forensically validated.
