Determination Method of Spatial Degrees of Freedom for Multi-Cameras in Shooting System of Autostereoscopic Display
the stereoscopic display effect is related to the parallax of stereo image pairs
and parallax is affected by cameras layout when the parallax images are captured. In the paper
camera calibration technique for binocular stereo vision system and the spatial geometric relationship are used to determine the position relation between any two cameras. And then the calibration result is applied to adjust the spatial position of the two cameras continually in order to make the two optical axes parallel to each other approximately. As a result
the image pairs acquired can guarantee a better stereoscopic display effect. Finally
the allowable variation range of the spatial angle between the two cameras is yielded experimentally. The results can be used to conduct the adjustment for the photography system of autostereoscopic display.
