Control of physical surface by detecting coordinates

Abstract

Theoretical and practical principles of the deter-mination of physical surfaces (of products) parameters and their control are presented. This method is realizable in the determination of spatial coordinates of surface points when CCD (coupled charge device) camera (matrix of photodi-odes) with focal lens is used. The method of linear inter-sections is used for recording point’s coordinates in a free coordinate system, when a baseline of two CCD cameras is established. Distance between the basic CCD camera and the point in question is obtained by adequate elements measured in CCD detector. Size of the examined physical surfaces (of products) could be up to some tens of meters. Formulas presented could be used for accuracy determina-tion of coordinates in question points.
