PROCESS FOR DETECTING THE THREE-DIMENSIONAL STRUCTURE OF AN OBJECT AND APPARATUS FOR IMPLEMENTING THE PROCESS

摘要

A process for detecting the three-dimensional structure of an object comprises the operating steps of: - feeding the object (1) along a movement path; - at a first detection zone (3) positioned along the path, detecting the geometric shape (4) of at least one section of the object (1); - again detecting the geometric shape (4) of the sections of the object (1) at least at a second detection zone (5); - repeating the detection steps for all of the transversal sections of the object (1) to obtain a plurality of partial geometric shapes (4); - for each section, comparing the geometric shape (4) detected in the first detection zone (3) with the geometric shape (4) detected in the second detection zone (5) to identify any movements by the object; and - combining the partial geometric shapes (4) to obtain the overall geometric shape of the object (1), taking into consideration any movements identified during the identification step.
