Abstract: A method of inspecting an object using a digital camera and a computing system involves comparing measured shape data obtained from a digital image of the object with digital reference data representing a nominal shape of the object, and generating an output indicating compliance or non-compliance of the measured shape of the object to the nominal shape of the object. The reference data is extracted from a CAD file by filtering CAD data based on characteristics of the entities that define the object in the CAD data. The filtering may involve extracting entity data based on the characteristics or excluding entity data from extraction based the characteristics.

Abstract: A method of assembling a plurality of objects comprises: creating a pixel map of a current scene in a work zone by mapping pixels of a camera to pixels of a projector; comparing the current scene pixel map with a corresponding previous scene pixel map; creating a projector pixel set depending on the differences between the current scene pixel map and the previous scene pixel map; and causing the projector to illuminate the work zone using the projector pixel set. The method may include a training mode in which the correct assembly steps are learned, a guidance mode in which a user is guided through the assembly steps, and a verification mode in which the actual assembly steps are verified.

Abstract: An optical probe having a hand held device with markers, a digital camera for digitally imaging the handheld device with markers, and a computer for calculating the position of the hand held device from the position of the markers in the digital image. This allows the hand held device to be used to take measurements, wherein the digital camera is a high resolution visible light digital camera and the markers are visible light markers.

Abstract: A system for inspecting an object, the system comprising a camera; a work surface for receiving the object; and an apparatus for processing an image of the object taken by the camera wherein, during the capture of an image by the camera, the camera and the object are fixed with respect to one another. The processing apparatus identifies those image data components that represent the an edge of the object in an image plane, and projects each image edge data component onto the object plane.
