description The invention discloses a dictionary optimization method. The structural features of light field data can be better carried, storage space for a dictionary can be reduced and reconstruction quality of a light field image can be obviously enhanced. The method comprises the steps that (1) the affecting process of an observation matrix and the dictionary based on a compressed sensing light field photography is researched; (2) a structured observation matrix P is derived according to the structure of a camera; (3) an optimized dictionary model is constructed through combination of inconsistency of the observation matrix and the dictionary in compressed sensing and compressed sensing and the sparse coding theory knowledge; (4) a structural dictionary SD is constructed according to high correlation between light field views and the similar structural content shared by all the views with combination of the structured observation P; and (5) the optimized dictionary model is solved according to the structured observat
