Embodiment 1

[0040] See figure 2 , figure 2 It is a flowchart of a method for collecting and displaying integrated imaging light field information provided by an embodiment of the present invention. As shown in the figure, the method for collecting and displaying integrated imaging light field information in this embodiment includes the following steps:

[0041] S1: Establish an integrated imaging model;

[0042] Specifically, the integrated imaging model includes a detector, an acquisition microlens array, a display screen, and a display microlens array. Wherein, the collection microlens array and the display microlens array are M*V two-dimensional arrays composed of evenly arranged microlenses, M represents the number of microlenses arranged horizontally, and V represents the number of microlenses arranged vertically. In this embodiment, the parameters of the collection microlens array and the display microlens array are the same, the detector is located at the focal plane of the col...

Abstract

The invention relates to an integrated imaging light field information acquisition and display method which comprises the following steps: establishing an integrated imaging model which comprises a detector, an acquisition micro-lens array, a display screen and a display micro-lens array; acquiring three-dimensional light field information of n different viewing angle areas of each acquisition micro lens through the detector, and generating a micro-unit image array, wherein n is greater than or equal to 2; equally dividing the persistence time of human vision into n time periods, wherein n isgreater than or equal to 2; and taking the micro-unit image array as a data source of the display screen, and sequentially displaying the micro-unit images corresponding to the ith viewing angle areaof each display micro-lens in a three-dimensional space in the ith time period, wherein i = 1, 2,..., n. According to the method, the tunable backlight direction and display screen content refreshingcan be accurately controlled, the micro-unit image information of different observation view angles is loaded at different moments within the human eye vision persistence time range, the crosstalk phenomenon is eliminated, and crosstalk light is converted into useful reproduced images.

Description

technical field [0001] The invention belongs to the technical field of integrated imaging three-dimensional display, in particular to a method for collecting and displaying integrated imaging light field information. Background technique [0002] Integrated imaging is a new three-dimensional display technology that integrates the recording of 3D scene micro-unit image arrays, the generation of display light field micro-unit image arrays and the display of 3D reconstructed images through lens arrays or camera arrays. A new three-dimensional display technology integrating field conversion and light field display. Integrated imaging 3D display has the characteristics of continuous viewpoint, full parallax, and full color. It does not require visual aids. It has good compatibility and inheritance performance with modern 2D flat panel displays. It is one of the naked-eye true 3D display technologies with the most potential for industrialization in the future. one. In the past t...
