摘要

The generalization of a new method for robust non-contact diameter determination of cylindrical objects is studied. The principle lays on laser telemetry under structured lighting, where laser planes create lines on the object under test, which are observed by a CCD camera. The calculation is performed thanks to what we call the "three-tangents method" which was proved as the most reliable one taking into account the particular curve's characteristics. So far the object was supposed standing perpendicular to the plane of the camera ; we extend the method - as a first step -to the diameter measurement of cylinders tilted either transversally or longitudinally to the camera's optical axis; Experimental results obtained on a pre-prototype caliper are given. A general accuracy of 1% for 10 to 30 cm diameter cylindrical objects is most often claimed for distances up to 2 m.
