Abstract
The invention provides an integrated imaging directivity display method based on pixel extraction. The method realizes the integrated imaging directivity display through pixels of extracted micro image arrays in different positions. Firstly, pixel arrangement of specific view points is determined according to the display equipment parameters and the watching feature parameters, only pixels of the specific view points are extracted for forming the extracted micro image arrays and are used for integrated imaging display, watchers only see three-dimensional images in the specific direction, and images in other directions disappear, so the integrated imaging directivity display is realized.
Description
Technical field
The present invention relates to three-dimensional stereo display method, a kind of more precisely integration imaging three-dimensional stereo display method.
Background technology
The integration imaging three-dimensional stereo display technique is a kind of any real tri-dimension Display Technique that helps the equipment of looking that need not.This technology has the advantages that bore hole is watched, and the process of its record and demonstration is simple relatively, and can show the stereo-picture of full parallax and authentic color, is one of hot research technology in the present three-dimensional stereo display technique.
The demonstration of integration imaging 3 D stereo has utilized the light path principle of reversibility; Record on the image recorder through the steric information of microlens array three-dimensional scenic; Generate little pattern matrix; Be shown in this little pattern matrix on the display device then, see through the three-dimensional scenic that microlens array demonstrates record.The three-dimensional scenic that integration imaging shows can supply many people to watch simultaneously at different directions.Be depicted as the sketch map of traditional integration imaging display packing like accompanying drawing 1, the beholder of different directions all can watch three-dimensional image, but the stereoeffect of finding stereo-picture is inequality, and what promptly see on the different directions is different side-informations.The integration imaging three-dimensional stereo display technique is except these advantages, and also there are numerous deficiencies in it, thereby has limited its practical application.The narrower visual angle of watching is exactly its important not enough point.Simultaneously, image primitive quantity is huge in the little pattern matrix of integration imaging, and Pixel Information is numerous in the image primitive, is unfavorable for the storage and the transmission of the dynamic video data of integration imaging.
