A new method for robust noncontact diameter determination of spherical objects is studied. Applications can be found in the grinding and in the robotic inspection fields. The principle is based on laser triangulation under structured lighting, where laser planes create lines on the object under test, which are observed by a charge-coupled device camera. Two(More)
The accurate acquisition of the patient dentition is a very important step in orthognathic surgery since it permits to determine the occlusal position in order to prepare the operation. Classical methods for dental acquisition do not give a fast, accurate and low cost solution. Moreover, orthognathic surgery requires accurate registration with CTscan(More)
The first part of the paper, mainly of tutorial nature, will be devoted to the presentation of the basic principles of 3D measurements by triangulation under lighting structured by laser planes. The metrological aspects will then be considered, namely the calibration of the measuring set-up. Finally, a series of industrial applications developed in the(More)
