A system and method for gaging the shape of a curved glass sheet includes, as components, (1) a system and method for acquiring three-dimensional surface data corresponding to the glass sheet, and (2) a system and method for receiving the acquired surface data, comparing the acquired surface to a pre-defined surface description, and developing indicia of the level of conformance of the contoured glass sheet to the pre-defined specification. The surface data acquisition system includes a conveyor for conveying the glass sheet, at least one display projecting a preselected contrasting pattern, and at least one camera. The camera(s) and display(s) are uniquely paired and are mounted in a spaced-apart relationship a known distance and angle from the surface of the glass sheet such that the camera detects the reflected image of the pattern projected on the surface of the glass sheet from its associated display.
