Embodiment Construction

[0034] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0035] figure 2 Schematic diagram of the combined imaging system. The system mainly consists of two parts: 1, 4, 3 are the acquisition part; 3, 4, 5 are the display part. The light emitted by the real object 1 is imaged by the lens array 4 and recorded on the recording plane 3 . When displaying, the display plane 3 is placed on the focal plane of the square lens array 4, and a stereoscopic image 5 can be generated according to the principle of reversibility of the optical path.

[0036] image 3 It is a schematic diagram of the structure of a square lens array, Figure 4 It is a schematic diagram of the structure of the honeycomb lens array. The pitch of the lens elements is p. In the lens array, the imaging efficiency η is defined as the effective light transmission area S of the lens array 有 with the total area S 总 The ratio of:

[0037] η = S 有 / S 总 (...

Abstract

The invention relates to a design method of a honeycomb type lens array capable of improving stereo image display resolution, and belongs to the technical field of stereo video display. The design method mainly comprises the following steps of comparing imaging efficiency, and setting a design object; performing optical design and imaging property analysis of a honeycomb type lens array formwork; matching the parameters of a display plane and the honeycomb type lens array. Compared with the traditional rectangular lens array, the method has the advantages that by adopting the honeycomb type lens array, the effective area of an optical device is sufficiently utilized, the imaging area is increased, the resolution of a stereo image is obviously improved, a high-quality three-dimensional reproductive image is obtained, and the realistic and stereo feel of watching can be improved.

Description

technical field [0001] The invention belongs to the technical field of stereoscopic video display, and in particular relates to a design method of a honeycomb lens array. Background technique [0002] With the development of science and technology and the improvement of people's living standards, the traditional two-dimensional display can no longer meet people's visual needs, and the stereoscopic video display technology with realistic effects and rich colors is currently a hot spot in the field of display research. The 3D stereoscopic display is closer to the human visual system, which can make the image have a sense of depth, three-dimensionality and reality, and provide people with more information. [0003] At present, stereoscopic display methods are mainly divided into two categories: stereoscopic display methods based on parallax, and true three-dimensional stereoscopic display methods. The first type of method is to make people's left and right eyes see different i...
