Paper Abstract

Light field planar homography is essential for light field camera calibration and light field raw data rectification. However, most previous researches assume light field camera as pinhole camera array and deduce the planar homography matrix of sub-aperture image, which is analogous to traditional method. In this paper, we regard light field as a whole and present a novel light field planar homography matrix based on multi-projection-center (MPC) model. The projections of point, line and conic are exploited based on light field planar homography. In addition, a camera calibration method and a homography estimation are proposed to verify the light field planar homography. Experimental results on light field datasets have verified the performance of the proposed methods.
