An overview on theory and algorithm of light field imaging technology

Abstract

With the continuous development of software and hardware technology, light field imaging technology has become the representative product of Frontier optics. The process of light field imaging can be divided into two parts: light field information acquisition and light field data processing. In this paper, the development process of light field imaging technology is summarized, and three kinds of acquisition methods of light field are introduced. Also, several main algorithms of light field imaging technology are summarized, whose advantages and disadvantages are analyzed. Finally, the application prospects and research direction of light field imaging technology are pointed out，emphasizing on the dynamic target monitoring based on camera array d the multi target autofocus imaging in special scene.
