Abstract

The invention discloses a method applied to optical field three-dimensional display quantification calibration. The method comprises the following steps: S1, generating a plurality of calibration source image data by three-dimensional software which can be developed secondly according to a field demand; S2, separating and sequencing the plurality of calibration source image data to construct a pixel sequence, and sampling and recombining the pixel sequence to obtain a calibrated secondary image with a fitted resolution; S3, loading the calibrated secondary image into a two-dimensional planar matrix display, and finely adjusting a cylindrical lens array or a micro lens by using a three-dimensional translation stage to achieve an optimal matching result; S4, repeating steps S2 to S3 to generate a quantified secondary image; and S5, loading the quantified secondary image into the two-dimensional planar matrix display, sampling an effect by using a charge coupled device (CCD), performing data processing and comparison to obtain a quantified effect, and detecting an optical field three-dimensional display effect. The method has the advantages that the quantification error is reduced greatly, and a calibration structure is more accurate.

Description

technical field [0001] The invention relates to the technical field of three-dimensional light field display, in particular to a quantitative calibration method for three-dimensional light field display. Background technique [0002] The three-dimensional display has the function of providing the depth perception of the three-dimensional scene. The objective world is three-dimensional in space, and the depth is the third-dimensional information. ) to perception (cognition of the three-dimensional world from two-dimensional images). The natural depth of human perception is due to the slight difference in viewing the real world with the left and right eyes, and the brain fuses the two to obtain a three-dimensional feeling. Most of the most common 3D rendering technologies currently used in entertainment and business circles still use methods based on stereoscopic viewing. The principle of this technology is to use various channels to present the images of the left eye and th...
