Patent ID: 7492470

Claim:
A method for three-dimensional shape measurement of a body or of a part thereof by scanning non-contact distance measurement using an optical sensor device, comprising the steps of: subjecting an area of the body to an impinging beam emitted by the optical sensor device at various incidence angles, creating a measuring beam reflected opposite to the impinging beam, measuring the reflected beam, with the body being adjusted relative to the optical sensor device depending on angle of reflection in order to ascertain a distance using the optical sensor device, determining the shape of the measured area, taking into account the measuring beam which describes an angle α to a surface normal corresponding to or assigned to the measured area, said angle being equal to or smaller than a predefined critical angle α GR relative to the surface normal, and not taking into account an angle x to a surface normal corresponding to or assigned to the measured area which is greater than the predefined critical angle α GR , and obtaining a data set representing the shape, which data set may be inputted to software for further processing.
