Focus feedback control with a deformable lens



Nikolaos Kariotoglou, Reto Hofmann

Adjusting the focus level of cameras to keep objects sharp while they are moving is a tedious task in film-making, requiring a long setup time and a dedicated cameraman responsible for "focus-pulling" (example). In this project we will use a deformable focus-tunable lens from optotune

to build an object-following focus controller. The lens has been mounted on an industrial camera connected to a processing unit capable of visually tracking objects on the camera view using state-of-the-art computer vision algorithms. The object-following focus controller will need to use the object tracking information and a metric for image sharpness to adjust the lens focus distance and keep the tracked object in focus as it moves towards and away the camera apparatus.
