Zusammenfassung:Disclosed is an apparatus (200) for reconstructing a three-dimensional profile of a target surface of an object. The apparatus (200) comprises: i) a lighting apparatus (206) having at least two modes of illumination to illuminate the target surface (202), 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 (202); ii) an imaging device (208) for capturing respective images of the target surface upon a sequential activation of the first and second modes of illumination of the target surface (202) by the lighting apparatus (206); and iii) a processor (210) 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 (202) of an object is also disclosed.
