Paper Abstract

According to integral imaging mechanisms, the spatial distortion of 3D integral image is affected by many parameters related to both the capture and the display setups, such as the shift and overlapping of elemental images, the aperture difference of the lens array between the capture and the display systems, the pitch between the adjacent lenses in the capture or display lens arrays. To solve this problem, we first clarify the effects of the optical parameter mismatch in pickup and display stage. An analytical model for the spatial distortion of 3D integral image caused by aberrations of the elemental images is then derived by the use of wave optics theories. Simulation results show that a 3D image is separated by local positional errors, and the reconstructed image is shifted in the depth direction. Moreover, the integrated 3D image has different magnification factors at longitudinal and lateral direction. Finally, we discuss the possibility to reduce the distortion of integral image through some methods proposed by previous researchers.
