Homogeneous light field model for interactive control of viewing parameters of integral imaging displays

A novel model for three dimensional (3D) interactive control of viewing parameters of integral imaging systems is established in this paper. Specifically, transformation matrices are derived in an extended homogeneous light field coordinate space based on interactive controllable requirement of integral imaging displays. In this model, new elemental images can be synthesized directly from the ones captured in the record process to display 3D images with expected viewing parameters, and no extra geometrical information of the 3D scene is required in the synthesis process. Computer simulation and optical experimental results show that the reconstructed 3D scenes with depth control, lateral translation and rotation can be achieved.
