Abstract: A system for three-dimensional reconstruction of a surface profile of a surface of an object is provided that utilizes a binary pattern projected onto the surface of the object. A binary string consisting of a series of “1”s and “0”s is first created, and a binary pattern of light that is constructed in accordance with the binary string such that bright and dark bands of light of equal widths correspond to “1”s and “0”s from the binary string respectively is projected onto the surface. The binary pattern is shifted with respect to the surface multiple times, during which an image of the binary pattern illuminating the surface is obtained at each position of the binary pattern. Thereafter, a height of each predetermined point on the surface is calculated relative to a reference plane based upon the images cumulatively obtained at said predetermined point.
