Abstract: The present invention relates to a system and method that includes a camera, a display and a processor wherein the camera captures a series of environmental images of an object, device or structure as the object, device or structure is assembled or constructed and then environmental image sis compared with a reference image. In exemplary embodiments, a reference standard image is displayed and, a user proceeds to manipulate objects to try to conform to the displayed referenced image. Next, environmental images are captured and a processor then compares the detected images against the reference standard and provides feedback to the user in the form of output that reflects compliance with the standard or a deviation from the standard. The feedback is provided, inter alia on a display panel so that the user can either confirm that the assembly is in conformance with the standard or see a graphical representation of how the assembly deviates from the standard.
