Abstract

A method and a system for creating three dimensional representation of an object are provided. The method includes projecting a pattern image comprising one or more pattern elements and capturing an image of the object with the pattern image projected onto the object. The method includes extracting intensity values corresponding to at least two color components of each pixel of the captured image. For each color component, a probability map is generated using the corresponding intensity values. The probability map for a color component represents a probability that a pixel of the captured image is representing a part of a pattern element. A joint probability distribution is determined by combining the probability maps. Using the joint probability distribution, specific pattern elements are located in the captured image. The method includes determining three dimensional coordinates representing points on surface of the object based on the location of the specific pattern elements.
