Abstract
In a method of and system for acquiring and digitizing an object through a transparent wall the system for acquiring and digitizing sections of objects includes a plurality of sensors carried by a common cradle. The sensors include a laser source emitting a lamellar beam forming a laser plane and two cameras observing the object. The various laser planes are coplanar and form a single measurement laser plane. Devices are provided for calculating and synchronizing the observed images. The support for the object to be measured has a non-plane surface. A preliminary phase includes calibration of the measuring space and acquisition and digitization of the surfaces of the transparent wall. Applications include acquiring and digitizing the shape of the human foot or a rubber seal for automobile doors when subjected to compression loads.
