Patent ID: 8780223

Claim:
In a system for visually comparing a part to a drawing of said part in computer memory or on a screen, the system comprising a camera for capturing either a single image or an image stream of said part, a computing module for receiving the image or image stream, for obtaining, scaling, positioning displaying said drawing of said part on a display unit and for overlaying the drawing on the image or image stream, a method for determining if a part is manufactured within predefined tolerances at least one control section, the method comprising the steps of: a. defining at least one control section, and for each control section determining the geometry thereof; b. performing a computer-aided-design-space (CAD-space) to image-space transformation of each control section; c. calculating a deviation between the CAD drawing and the part at each control section; d. providing a user with an indication of the deviation between the CAD drawing and the part at each control section; e. comparing the deviation to a predetermined tolerance in order to determine if the part at each control section is within the predetermined tolerance; and f. providing a user with an indication of the determination of each control section being within the predetermined tolerance.
