Shape from focus for large image fields
Result description
Shape from focus is a method for the accurate measurement of the geometrical shape of objects. The measurement principle is the local focus search. The method is suitable only for objects with a texture (optically rough surface). The longitudinal coordinate of a surface point is determined from the maximum of the focus measure function. The focus measure function expresses the quality of focus in a small image area. The measurement is fast because the focus measure function shows no oscillations. Thus,a large sampling step can be used. We present experimental results that demonstrate the capability of the proposed method.
