Procedure for optical measurement of the shape of reflecting outer surfaces by use of single value, wavelength or intensity, light sources so that a single valued image pattern is obtained

摘要

Procedure in which the space above the object is illuminated with light the intensity and or wavelength of which is coded with respect to the origination direction of the light beam. The coding is single valued so that light of a certain intensity or wavelength originates only from one point. A camera is then used to record the reflected image from the outer surface of the reflective object. The camera image is a three dimensional coding of the space above the object.
