Abstract

Devices, systems, and methods for imaging and measuring deflections in structures such as railroad rail are disclosed. One exemplary embodiment relates to a vision system having a high-speed, visible-light imaging camera and an evaluation unit configured for analyzing images from the camera to detect geometric variations in the structure. In a second example, additional sensors are used to identify the wheel location(s) in the same reference frame as the mea Surement system. In analyzing structures Such as railroad track rail, the imaging camera can be coupled to a moving rail vehicle and configured for generating images of the rail as the vehicle moves along the track.
