Abstract:
1. A method for contemporaneously reconstructing images captured of a scene being illuminated with unstructured and structured illumination sources having significantly overlapping spectral characteristics, the method comprising: capturing at least a first 2D image of a subject's exposed skin containing energy reflected from a scene being illuminated by a structured illumination source projecting patterns of light onto said scene, said first 2D image being acquired by a video camera that is sensitive to electromagnetic radiation in a wavelength of said structured illumination; capturing at least a second 2D image of said subject's exposed skin containing energy reflected from the scene being illuminated by an unstructured illumination source; and contemporaneously reconstructing a 2D intensity map of said scene using said second 2D image, said 2D intensity map is a map of said subject's vascular pattern containing blood vessels which transport hemoglobin, and reconstructing a 3D surface map of said scene using said first 2D image, said contemporaneous reconstruction being effectuated by manipulating said illumination sources during capture of said first and second 2D images, said manipulating comprising:
