Polarization stereoscopic imaging prototype

The polarization of light was introduced last ten years ago in the field of imaging system is a physical phenomenon that can be controlled for the purposes of the vision system. As that found in the human eyes, in general the imaging sensors are not under construction which is sensitive to the polarization of light. These properties can be measured by adding optical components on a conventional camera. The purpose of this thesis is to develop an imaging system that is sensitive both to the stereoscopic and to the state of polarization. As well as the visual system on a various of insects in nature such as bees, that are have capability to move in space by extracted relevant information from the polarization. The developed prototype should be possible to reconstruct threedimensional of points of interest with the issues associated with a set of parameters of the state of polarization. The proposed system consists of two cameras, each camera equipped with liquid crystal components to obtain two images with different directions of polarization. For each acquisition, four images are acquired: two for each camera. Raised by the key of main capability to return polarization information from two different cameras. After an initial calibration step; geometric and photometric, the mapping of points of interest process is made difficult because of the optical components placed in front of different lenses. A detailed study of different methods of mapping was used to select sensitivity to the polarization effects. Once points are mapped, the polarization parameters of each point are calculated from the four values from four images acquired. The results on real scenes show the feasibility and desirability of this imaging system for robotic applications.
