Abstract

The present invention proposes a crosstalk quantitative estimation method for a slit grating naked-eye 3D display, comprising the following steps: acquisition of physical parameters; acquisition of overlapping factor relationship; acquisition of overlapping area; acquisition of brightness contrast curve; and quantitative acquisition of crosstalk. The present invention provides a crosstalk quantitative estimation method, device and storage medium for a slit grating naked-eye 3D display, which provides a reference method for solving the problem of slit grating naked-eye 3D crosstalk, and prevents visual vertigo caused by the crosstalk problem for naked-eye 3D display , The feeling of fatigue opens up the direction of solving the problem, which will greatly benefit the application development of the slit grating naked-eye three-dimensional display.

Description

technical field [0001] The invention relates to a method for quantitatively estimating crosstalk of a slit grating naked-eye 3D display. Background technique [0002] The slit grating naked-eye 3D stereoscopic display realizes stereoscopic display through the occlusion effect of the slit. The slit grating naked-eye 3D display based on binocular parallax allows the left and right eyes to see respectively when the viewing position is correct through the occlusion effect of the slit. respective images, thereby producing stereoscopic vision. [0003] The current bottleneck of binocular parallax naked-eye 3D display lies in visual dizziness and fatigue, which largely affects the large-scale application of naked-eye 3D display. Vertigo and fatigue are caused by "crosstalk". The main reason is that the eyes deviate from the correct position, that is, the left eye can see part of the pixel image of the right eye or vice versa. The crosstalk of the naked-eye 3D display is the key t...
