description

Nowadays, visual inspection is very important in the quality control for many industrial applications. However, the complexity of most 3D objects constrains the registration of range images; a complete surface is required to compare the acquired surface to the model. Range finders are very used to digitalize free form shape objects with large resolutions. Moreover, one single view is not enough to reconstruct the whole surface due to occlusions, shadows, etc. In these situations, the motion between reconstructed partial views are required to integrate all surfaces in a single model. However, the use of positioning systems is not always available or adequate due mainly to the size of the objects or the environmental conditions imposed by the precise mechanics which suffer from vibrations present in the industry. In order to solve this problem, a 3D hand sensor is developed to reconstruct 3D objects that let us to compare them with respect the original one.
