Abstract
Disclosed is an apparatus for reconstructing a three-dimensional profile of a target surface of an object. The apparatus comprises: i) a lighting apparatus having at least two modes of illumination to illuminate the target surface, wherein a first mode of illumination produces a pattern onto the target surface and a second mode of illumination illuminates every part of the target surface; ii) an imaging device for capturing respective images of the target surface upon a sequential activation of the first and second modes of illumination of the target surface by the lighting apparatus; and iii) a processor for reconstructing the three-dimensional profile of the target surface based on the images of the target surface as captured by the imaging device. A method of reconstructing a 3D profile of a target surface of an object is also disclosed.
