LASER ALLUMINIO: Real-time acquisition for laser welding monitoring

The objective of this project was to develop a vision system for the real-time acquisition and saving of images produced in laser welding processes. This activity represents an initial step in the context of a research project aimed at studying the relation among the welding parameters and the quality of the welds, as they are captured by the vision system, for the feedback of the welding parameters during the welding.

The Laboratory worked in collaboration with TubeTech Machinery srl (Cazzago San Martino, Brescia, Italy), that was the company interested into this study.
The hardware used to devop this application is the Embedded Vision System (National Instruments) with LabVIEW 8.6.1, the IMAQ Vision libraries and the Real Time module for LabView. The vision system is based on the cooperation between a Host PC (PCS), and the NI EVS 1464 device. The acquisition campaigns have been done on one of the welding machines  available at TubeTech Machinery.

Suitable image elaboration tools have been developed to extract information from the videos captured by the system.

Real time acquisition of silhouettes

The aim of this project is to design, implement and charaterise a vision system for the 3D reconstruction of objects rotating with respect to their axis by means of the Silhouette method. The system has been developed using LabView Real-Time 8.6.1 (National Instruments, NI).

 The hardware of the system is composed by the NI Embedded Vision System (EVS), the  Basler Scout scA1390-17gm/gc Gigabit Ethernet camera, and a telecentric lighting system combined with a telecentric optics (Optoengineering, Italy). The software tools dedicated to image acquisition and elaboration have been developed by using the NI-IMAQ vision libraies. The vision system is called  ‘OPTOSILHO‘.
