Depth Calculation Method of Integral Imaging Based on Gaussian Beam Distribution Model

In this paper, we propose a concept of the optimal viewing distance range and a depth calculation method of integral imaging. By considering the light emanating from a single elemental image point as a Gaussian beam, we analyze the integral imaging depth range and deduce the depth calculation formulas in different display modes. Experiments in focused mode were carried out, and good results finally confirmed the feasibility of the proposed method.
