Abstract
The parameters p of analytical elements in space (straight lines, circles, spheres, cylinders, etc.) are determined by minimizing the distance between the rays related to a contour of an element in the images and the element in space itself. The coordinates of a contour assigned to an element are determined with subpixel accuracy using a complex filter algorithm, which automatically follows a line. The proposed method does not need marks on the object to calculate the desired parameters. Hence it is especially suited for quality control in industrial applications.
