Abstract
A system for visually comparing a part to a drawing of said part in computer memory or on a screen is provided. The system includes a camera for capturing either a single image or an image stream of the part, a computing module for receiving the image or image stream, for obtaining, scaling, positioning and displaying the drawing of the part on a display unit and for overlaying the drawing on the image or image stream. The system determines if the part is manufactured within predefined tolerances at least one control section. In use, a user defines at least one control section and the system performs a CAD-space to image-space transformation of each control section. A deviation between the CAD drawing and the part at each control section is calculated, and this deviation is indicated to the user. The deviation is compared to a predetermined tolerance in order to determine if the part at each control section is within the predetermined tolerance; and a pass/fail indication is determined based on the comparison. For more complex shapes, a user can select an entire geometrical shape, and the system automatically determines a plurality of control sections within the geometric shape, in order to provide the user with a shape pass/fail indication.
