Abstract
A system for acquiring surface data from one of the surfaces of a curved panel having a specular surface and developing a surface definition of the panel includes a conveyor for conveying the panel in a first direction, at least one display projecting a preselected multi-phase non-repeating contrasting pattern, and at least one camera, each one of the cameras uniquely paired with one of the displays. The system may also include a control programmed to execute logic for controlling each of the camera/display pairs to acquire the desired images, and logic for analyzing and combining the data acquired by the cameras to construct a definition of the surface of the panel.
