Abstract
An image processing system includes an object illuminated by a pre-determined first spectrum of light and an array of fringe lines, an imaging device configured to capture an image of the object including the first spectrum of light and the fringe lines reflecting from a surface of the object, and a processor in signal communication with the imaging device to receive an input data representing the image of the object, wherein the processor: generates a first data model based on the input data; removes a DC-component from the first data model to create a second data model; and performs a two dimensional Fourier transform profilometry based on the second data model.
