Place: Room C104, Sexton Campus, Dalhousie University, 1360 Barrington Street, Halifax, Nova Scotia, Canada (Map)


Visual sensing is important to many engineering applications including 3D measurements for industrial automation and robotics. Efficient measurement and reconstruction of a 3D object requires a suitable vision system setting and view point planning strategy. In this talk, I will present our work on active vision and view planning using our active vision system which is reconfigurable. With the recalibration method developed, the system parameters can be calibrated automatically whenever the configuration of the system is changed during a measurement task. Such recalibration requires only a single image of the scene, allowing the 3D measurement and reconstruction to be performed online without interruption, making it adaptable to the measurement environment. Using the active vision system, we investigated issues in multi-view visual measurement, and tracking tasks for robotic applications.
