Cars go through inspection inside a black tent with a collection of 16 cameras and eight projectors attached to its inner structure. An additional camera is positioned below the vehicle to measure the underside.
Once a car rolls in, the projectors cast light in a series of lines and dots over the body to create a coordinate system for the cameras. In roughly 30 seconds, those cameras capture the measurements of those light patterns and create a 3-D heat map — also called a point cloud — that helps officials determine whether a car is in compliance.
