THE TRIANGULATION METHOD OF CONTACT-LESS DIMENSION MEASUREMENT USING AN AREA CMOS IMAGING SENSOR

Jan Fischer, Tomáš Radil, Jan Šedivý

Abstract

The so-called triangulation method of contact-less dimension measurement determines the measured object’s dimension from its shadow projected on an imaging sensor without lens. A point light source is used to illuminate the measured object. The so far used linear CCD sensors introduced a considerable uncertainty to the measurement. Application of area CMOS imaging sensors improves the measurement uncertainty and enables to use some new measurement methods. A special CMOS measuring camera was designed for this purpose.
