Abstract
Deviation between an upper portion and a lower portion of a screw hole is recognized. This is accomplished by imaging holes in respective objects to obtain a contrast image. The position of the hole in the upper object and the lower object is detected. The deviation between the positions is calculated. Screws are tightened sequentially beginning with the hole having the smallest deviation. The rotation angle of the object to be tightened is determined. From this rotation angle, the deviation of other holes is calculated.
