IVIS: An Integrated Volumetric Inspection System

摘要

A novel approach to automated visual inspection based on comparing a volumetric model of a reference object to a volumetric model of an actual object which is iteratively created from sensor data is presented. The use of volumetric models gives this approach a number of distinct advantages over more traditional surface-based methods. First, there is no need to identify "features," which is important when inspecting objects whose features are difficult to identify. Second, volumetric inspection lends itself naturally to multisensor applications. Finally, true 3-D comparisons of the reference and sensed objects can be easily carried out using volumetric models.
