Abstract: A system and method for surface profiling via a projection system, such as a position enabled projector. By way of example, a three-dimensional representation of a physical object, such as an uneven surface of the object, may be generated and profiled. The three-dimensional representation may be a 3D point cloud, a surface mesh, or any other suitable type of representation. A two-dimensional image to be projected onto the surface may undergo an image transformation based on the generated 3D representation of the surface. The transformed image is then projected onto the surface, where the image points projected are at their true positions with true scale. Moreover, the projected image may be automatically updated when the projector is moved to a new position.

Abstract: The invention is directed to a system and method for recalibrating a projector system. The projector may be calibrated using one or more cameras arranged near or adjacent to a projector of a projector system. The one or more cameras may be calibrated once and made mechanically stable so that they do not move relative to each other. During operation of the projector system, the projector may project one or more specific patterns onto a work surface, where the one or more cameras capture each of the projected patterns. All the captured images of the patterns by the one or more cameras may be used to determine projector calibration parameters in order to recalibrate the projector.
