摘要：

To improve the performance of 3D light field display(LFD) devices and optimize their display effects, a depth-of-field (DOF) enhancement in LFD based on fusion of voxel information on the depth plane is proposed. In previous research, a calculation method was developed to calculate the voxel size on the depth plane. According to this calculation method, a distribution model of voxel varying with display depth is established. A DOF determination criterion based on voxel distribution from visual perspective is proposed, and its accuracy is validated through subjective experiments involving multiple participants. By fusing the voxels on the depth plane, the phenomenon of voxel overlap is improved, resulting in enhanced definition of 3D images on the depth plane. Under the condition that the structure and parameters of the 3D LFD device are determined, the maximum achievable display depth will be increased significantly. Finally, experimental validation of the method's feasibility is conducted using multiple 3D light field devices for display. © 2024
