Optolab, Laboratory of excellence for vision, optoelectronics, optics and lasers
|
Welcome to the website of Optolab BS, a Laboratory of excellence at the University of Brescia (Italy), committed to research and development, industrial liaisons, start-ups, development, testing, and teaching/education and consultancy in the fields of vision, optoelectronics, lasers, optics and their applications.
The Laboratory activity in Vision includes three-dimensional and two-dimensional vision, camera calibration, development of range cameras for reverse engineering, 3-D measurement and quality control, non destructive testing, biomedical imaging, vision for cultural heritage documentation and forensics. Vision is also applied to robotic cells for enhanced flexibility, and to the on-line quality control of industrial processes such as laser aluminum welding.

 Look at the video to appreciate how 3D vision combined to a robot arm can increase the system flexibility in picking operations. The robot is a DENSO VS-6556G system. A laser slit is mounted close to the end effector, and scans the scene. Suitable 2D geometric Template Matching is used to get information on the scene.

The aim of this project has been to design, to implement and to characterize the calibration procedure specifically developed for a laser slit using two laser line projectors and one videocamera. The system has been called 'bikini', for the reason that it is based on two light sources, and that...we started to design it on Summer, when people were at the seaside. The laser projectors can be oriented either symmetrically or non-symmetrically with respect to the camera. The presentation below gives more information on this topic.

In this work, a vision system specifically designed to monitor the labels on bottling lines for wine is presented. The system is based on smart cameras, Real Time LabView sofware and Imaq vision libraries. The work has been developed in the frame of a thesis work, in collaboration with Studio Progetti Automation srl (Italy). The following presentation gives a short insight of the work. For further details, please contact us.

This project deals with the design, the development and the characterization of a vision system based on passive stereo vision, using the Halcon 9.0 (MVTech) suite of functions for 3D vision. The measurement procedures have been developed in the VISUAL BASIC.NET platform. Special care has been dedicated to devop a flexible software tool, denominated CHAMALEONEYES, which allows the user to automatically unload the cameras, and to calibrate them in a fast and easy way.
Special panels are available to check the hardware status, to load new camera models, and to test them. The tool outputs the point cloud corresponding to the field of view acquired by the cameras. Look at the presentation below for furthet information, or contact us!

The aim of this project is to add 2D vision to the BARMAN demonstrator shown in the figure. The BARMAN is composed of two DENSO robots. In its basic release it picks up bottles, uncorks them and places them on the rotating table. It then rotates the table, so that people can pick them up and drink.

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. Look at this presentation for further details, or contact us!

Image analysis tools have been developed to elaborate images acquired from an on-line laser welding process. The aim was to perform a preliminary investigation on the possibilities deriving from image analysis of a welding process, to establish a correlation between the information carried out by the images, and the process parameters (laser power, welding speed etc). Take a look to the presentation below, or contact us for further details!
