Stereo-pair images obtained from two cameras can be used to compute three-dimensional (3D) world coordinates of a point using triangulation. However, to apply this method, camera calibration parameters for each camera need to be experimentally obtained. Camera calibration is a rigorous experimental procedure in which typically 12 parameters are to be(More)
This paper discusses the calibration phase required prior to working of any gesture recognition or eye tracking devices. The calibration phase is an starting phase of eye tracking system. Prior to tracking phase, calibration (for eye detection) is required. Four methods have been tried in this paper, namely: using a box, multiple frames, laser and neural(More)
