Abstract:
1. A method of performing 3-D (three-dimensional) object profile inter-planar estimation and/or range inter-planar estimation of one or more objects within a scene, said method comprising: a) providing a predefined finite set of distinct types of features, giving rise to feature types, each feature type being distinguishable according to a unique bi-dimensional formation; b) providing a coded light pattern comprising multiple appearances of said feature types; c) projecting said coded light pattern, having axially varying intensity, on one or more objects within a scene, said scene having at least two planes, giving rise to a first plane and to a second plane; d) capturing a 2-D (two-dimensional) image of said objects having said projected coded light pattern projected thereupon, thereby giving rise to a captured 2-D image, said captured 2-D image comprising reflected said feature types; e) determining intensity values of the 2-D captured image, giving rise to the determined intensity values; and f) performing 3-D object profile inter-planar estimation and/or range inter-planar estimation of said one or more objects within said scene based on said determined intensity values.
