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.
