Abstract: An inspection station includes a conveyor, a first scanner, a second scanner, a controller, and an interface. The conveyor is configured to continuously transport a vehicle body through the station. The first scanner is configured to detect features of the vehicle body and associated feature coordinates relative to a global coordinate system. The second scanner is configured to detect paint thicknesses on surfaces of the vehicle body and associated paint thickness coordinates relative to the global coordinate system. The controller is programmed to map corresponding pairs of the feature coordinates and paint thickness coordinates into a single set of local coordinates having a datum defined by the vehicle body such that each of the local coordinates defines a location of one of the features relative to the datum and one of the paint thicknesses at the location. The interface is configured to display the features and corresponding paint thicknesses.

Abstract: Systems, apparatuses, and methods for measuring material thickness of multiple tubulars by placing a logging tool in a well with multiple conductive tubulars and generating an electromagnetic field that interacts with the tubulars. A logging tool obtains the measurements using one or more receivers. A monitoring system or the logging tool applies the measurements to a mathematical model that considers at least a transition zone and one or both of a near field zone and a remote field zone of the electromagnetic field that interacts with the multiple conductive tubulars. Furthermore, the monitoring system or the logging tool may ascertain a thickness of the one or more conductive tubulars using the mathematical model.
