Abstract
A structured light pattern comprising at least two sub-patterns in the direction of motion are projected onto an object during in-line inspection. Images of the object are captured for each sub-pattern. The sub-patterns are used to establish correspondence and to construct a profile using dense per pixel camera-projection correspondence.
