Watch Sunday: Live inspection stream from New Hampshire

On Sunday, NASCAR Digital is live streaming the Monster Energy NASCAR Cup Series inspection process from a camera inside the Optical Scanning Station on our YouTube channel from 9-11 a.m. ET. Bookmark our YouTube channel here to watch, or come back to this article, where we'll embed the YouTube stream (below). 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.
