Problems solved by technology

[0005] This technology uses exactly the same microlens array for two recordings, which will result in a black border area on the second recorded image. As the distance between the two microlens arrays increases, the black border area will also increase.
When reproduced, the black border will seriously affect the viewing angle

Embodiment Construction

[0019] A typical embodiment of using the present invention to perform two-step integrated imaging and recording of a three-dimensional scene will be described in detail below, and the present invention will be further described in detail. It is necessary to point out that the following examples are only used for further description of the present invention, and cannot be interpreted as limiting the protection scope of the present invention, and those skilled in the art make some non-essential improvements to the present invention according to the above-mentioned content of the present invention And adjustments still belong to the protection scope of the present invention.

[0020] The steps of using the present invention to carry out two-step integrated imaging recording of the three-dimensional scene are as follows:

[0021] In the first step, it is determined to reproduce a three-dimensional scene with a non-expanded microlens array whose parameters are m×n=120×90, f=10mm, a...

Abstract

The invention provides a method for solving the problem of black borders in two-step integration imaging. An expanded micro-lens array is adopted when a first record is carried out on a three-dimensional scene; the produced first record reproduces a real image with depth reversal of the three-dimensional scene in a space through the expanded micro-lens array; and then a non-expended micro-lens array is used for carrying out a second record on the real image, and the second record image without black borders is produced and is used for integration reappearance.

Description

1. Technical field [0001] The invention relates to integrated imaging three-dimensional display technology. 2. Background technology [0002] The 3D display technology based on the two-step integrated imaging method is a true 3D stereoscopic display technology, which is divided into two parts: recording and reproduction. [0003] The recording process includes the first recording and the second recording. For the first recording, the microlens array is used to obtain stereoscopic information of different angles of the three-dimensional scene, and the information is recorded on the focal plane of the microlens array to generate the first recorded image; the first recorded image passes through its corresponding microlens array A depth-inverted real image of the three-dimensional scene is reproduced in space, and the depth-inverted real image is recorded a second time with the same microlens array, and the second record is recorded at the focal plane of the second microlens ar...
