Claim Text:
1. A method of creating maps of a subject's skin in a scene captured by a video camera comprising: capturing: (i) a first 2D image containing energy reflected from a subject's skin being illuminated by a structured illumination source projecting a pattern of light onto the subject's skin, said first 2D image being captured with a video camera that is sensitive to electromagnetic radiation in a wavelength of the structured illumination source; and (ii) a second 2D image containing energy reflected from the subject's skin being illuminated by an unstructured illumination source; during capturing of the first 2D image and the second 2D image, varying the structured and unstructured illumination sources such that the structured illumination source and the unstructured illumination source are not projecting light on a same region of interest of the subject's skin at the same time during capturing of the first 2D image and capturing of the second 2D image; and reconstructing a 2D intensity map using the second 2D image having been illuminated by an unstructured illumination source and a 3D surface map using the first 2D image having been illuminated by a structured illumination source, wherein said 2D intensity map is a map of said subject's vascular pattern containing blood vessels which transport hemoglobin.
