This paper presents a system for eye gaze tracking. The system consists of two CCD cameras and two novel light sources for stereovision. We propose a method for system calibration of gaze tracking system, in which camera is not directly facing the screen and light sources. A planar mirror is used to make them visible to the camera. Using planar calibration patterns, we can uniquely identify the reflection...
In this paper we describe an approach for 3D-TV Layered Depth Video (LDV) - Content creation using a capturing system of four CCD - Cameras and Time-Of-Flight-Sensor (ToF - Camera). We demonstrate a whole video production chain, from calibration of the camera rig, to generation of reliable depth maps for a single view of one of the CCD - Cameras, using only estimated depth provided by the ToF - Camera...
A simple method for lens calibration is presented. The method uses a fiducial disc and straightedge which are placed imprecisely within the field of view. Several inexpensive 6mm lenses and CCD cameras were used to validate the method. It is fast and accurate to a variance of less than half a pixel, which makes it a useful tool for computer vision.
