HYSCAS* stands for Hybrid Stereo Calibration Software and is a cross-platform tool. From a set of synchronized image acquisitions of a calibration pattern (chessboard, ...), the simultaneous intrinsic and extrinsic parameters of a stereovision rig is led. The improvement of HYSCAS over existing calibration softwares or toolboxes is to completely calibrate rigs composed by different cameras modeled by different projection models as, for instance, a rig composed by an omnidirectional camera, modeled by the stereographic projection model of Barreto, and a perspective camera, modeled by the so called pinhole projection model. The major interest of mixing projection models is to use the most adapted model for each camera of the rig.
*HYSCAS has been developed by Guillaume Caron and Damien Eynard in the M.I.S. laboratory of University of Picardy Jules Verne of Amiens.
HYSCAS allows to calibrate:
- a single perspective camera using the pinhole model or the unified model of Barreto
- a single central omnidirectional camera using the unified model of Barreto or the ad hoc model for a paracatadioptric camera
- a rig of N cameras using the same model
- a rig of N cameras using any available model for each camera
