Abstract:
A system is disclosed including an image sensor positioned at a first specified angle relative to a projected image plane. The system includes a projector that projects a test pattern onto the projected image plane. A controller is structured to iteratively adjust the projector focus until an image focus index is maximized, where the image focus index is a function of an amplitude of at least one harmonic frequency of a scan of the test pattern. The controller is further structured to determine a skew indicator value and adjust a projector skew adjustment. The controller is further structured to compare a current zoom level to a target zoom level and adjust a projector zoom. The projected image plane is a manufacturing surface, where the projected image is utilized in a manufacturing process.
