Resolution analysis of focused plenoptic camera with four types focal lengths
Abstract
The plenoptic camera is a new camera structure which can record the intensity, color and the direction of the light by adding a microlens array in front of the image sensor. Based on some basic concepts of the focused plenoptic camera, we first analyze the imaging characteristics. Then, the design method was given. Furthermore, we establish the depth resolution model after detailed derivation. The imaging characteristics of the focused plenoptic camera with a novel structure of four types focal lengths microlens array was analyzed. The simulation results show that our designed camera has the advantages of large depth of field and high depth resolution. The method proposed in this paper can provide reference for designing plenoptic cameras for specific application scenarios.
