An inexpensive computer imaging system is being developed which is capable of accurately recovering the three-dimensional surface of the human body. This system uses biologically safe structured white light. In structured light, a uniform square grid pattern is projected onto the skin and an image of this pattern is recorded using a single camera. The squares in the camera image appear distorted due to the curvature of the skin. By locating the intersections of the grid stripes and matching them correctly to the projected grid pattern, the three-dimensional positions of points on the skin surface can be determined by triangulation. Triangulation is the method by which an illuminated point on the object surface may be located in space as the intersection of two lines: the illuminating ray from the projector and the line of sight determined by the location of the point in the camera image. This system has been applied to measure facial swelling and the surface area of burns. This paper summarizes the steps in processing an image to reconstruct a surface patch of a portion of the skin. We discuss the geometry of the imaging system and show how three-dimensional information can be recovered. Next, we describe the actual processing steps and algorithms used to locate the data used to reconstruct the patch. A unique feature of the system is the compensation for the reflectance of the skin. Experiments are discussed figures are presented illustrating the various processing steps. These preliminary results demonstrate the feasibility of the imaging system in accurately reconstructing a surface patch of the skin. Finally, we summarize the present state of our project and discuss work in progress and future plans.
