Popis
Shrnutí:Light field display (LFD) is considered as a promising technology to reconstruct the light rays’ distribution of the real 3D scene, which approximates the original light field of target displayed objects with all depth cues in human vision including binocular disparity, motion parallax, color hint and correct occlusion relationship. Currently, computer-generated content is widely used for the LFD system, therefore rich 3D content can be provided. This paper firstly introduces applications of light field technologies in display system. Additionally, virtual stereo content rendering techniques and their application scenes are thoroughly combed and pointed out its pros and cons. Moreover, according to the different characteristics of light field system, the coding and correction algorithms in virtual stereo content rendering techniques are reviewed. Through the above discussion, there are still many problems in the existing rendering techniques for LFD. New rendering algorithms should be introduced to solve the real-time light-field rendering problem for large-scale virtual scenes. •Various light field display technologies and virtual stereo content rendering technologies are summarized.•The advantages and disadvantages of each virtual stereo content rendering technology are studied.•The light field image coding, correction and synchronization algorithms are summarized.
