Computer Vision Systems Laboratory

The Computer Vision Systems Laboratory is a richly equipped working environment for our team's research and development pursuits.

Three-dimensional scanner MINOLTA VI-9i

Our recently purchased Minolta Vi-9i three-dimensional scanner by Konica Minolta is one of very few such devices in Poland.

Mobile stereoscopic head

A highlight of the laboratory is the mobile stereoscopic head, designed and built under one of our research projects. It is a small autonomous vehicle moving on caterpillars and carrying a stereo pair of cameras on a moving arm.

Human eyeball movement system OBER2

The Ober2 system is used in research into abnormalities of human eyeball movement. It relies on the reflective properties of the eyeball in the infrared part of the spectrum. Sending pulses of IR light towards the eye, the system measures the intensity of the reflected beam. Two emitter-sensor pairs are placed on eather side of the eye, and the difference between their received signals is proportional to the angular position of the eye.
