PROPERTIES OF A BINOCULAR STEREO VISION MODEL

Binocular stereo vision is one of important branches of stereo vision. This paper first introduces a binocular stereo vision model. Then focuses on the stereo effects that can be seen through the model (i.e. the model’s properties): the method to calculate the coordinates of stereo pairs is given, properties of parallax are presented, and the stereo effects when eyes moving in the same plane which parallels with the screen are also discussed. Finally, conclusions drawn in the paper are proved by experiments. The results show that if the distance between observer and screen do not change, he won’t feel the objects move away or come close when he shakes his head slightly, but he will feel the whole image is swaying. Though slight differences exist for different people, the phenomena each person sees accord with predictions we deduce from the model.
