Contemporaneously reconstructing images captured of a scene illuminated with unstructured and structured illumination sources

摘要

What is disclosed is system and method for contemporaneously reconstructing images of a scene illuminated with unstructured and structured illumination sources. In one embodiment, the system comprises capturing a first 2D image containing energy reflected from a scene being illuminated by a structured illumination source and a second 2D image containing energy reflected from the scene being illuminated by an unstructured illumination source. A controller effectuates a manipulation of the structured and unstructured illumination sources during capture of the video. A processor is configured to execute machine readable program instructions enabling the controller to manipulate the illumination sources, and for effectuating the contemporaneous reconstruction of a 2D intensity map of the scene using the second 2D image and of a 3D surface map of the scene using the first 2D image. The reconstruction is effectuated by manipulating the illumination sources.

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:
sequentially alternating a projection of said structured and unstructured illumination sources such that neither of said illumination sources is projecting light onto a same region of said subject's exposed skin in said scene; andselectively choosing a first and second region of interest in said scene, said first region being illuminated by said structured illumination source and said second region being illuminated by said unstructured illumination source such that neither of said sources is concurrently projecting light onto a same region.
