Structured-light system is widely used for reconstructing 3D objects in machine vision. One of the major tasks in establishing such a system is the laborious and tedious calibration of the sensors. This paper presents a new method which dynamically calibrates the system automatically, if and when the relative pose between the camera and the projector is changed. A distinct advantage of this method is that neither the design of a calibration pattern/device nor the pre-knowledge of the movement of camera or scene is required. Several important cues for self-recalibration, including geometrical cue and focus cue, are explored in this paper. Finally, some experimental observations are presented to illustrate the implementation of this new method.
