1. A method of producing a planar form of a non-planar skin surface including a surface feature comprising: a. projecting structured light onto the skin surface, the structured light including a plurality of fan-beams projected such that at least some of the fan-beams cross in front of the camera, each fan-beam projected so as to form a structured light stripe on the skin surface; b. capturing an image of the skin surface including the surface feature and structured light stripes on the skin surface; c. determining, by a computing device, three-dimensional coordinates of the structured light stripes within the image; and d. unwrapping, by the computer device, the image based on the three-dimensional coordinates of the structured light stripes to produce a planar form of the surface.
