Method and system for evaluating resolution index in naked eye stereoscopic display

Abstract

The invention relates to a method of evaluating a resolution index in naked eye stereoscopic display. The method comprises the following steps: S1, the brightness of a naked eye stereoscopic display device to play a pure white picture in a 3D mode is acquired and marked as E; and the illumination L1 of the naked eye stereoscopic display device to play the pure white picture in the 3D mode and the illumination L2 when a pure black picture is played are acquired; S2, the E, the L1 and the L2 are used for building a spatial frequency-contrast threshold curve C(f); S3, the naked eye stereoscopic display device displays a tested picture in the 3D mode, the image displayed by the naked eye stereoscopic display device is photographed, the photographed image is processed, and the contrast of the photographed image is thus acquired; S4, the spatial frequency of the photographed image is solved; and S5, according to the contrast of the photographed image and the spatial frequency, a corresponding point is determined in the f-C space, and a resolution loss condition is judged through the relation between the point and the spatial frequency-contrast threshold curve C(f), wherein the resolution loss conditions are as follows: if the point is lower than the threshold curve, resolution loss happens; and if the point is higher than the threshold curve, the resolution has no loss and is unchanged.

AI Technical Summary

Benefits of technology

This technology allows for better understanding when switching between two modes: 1) In one mode (the normal viewing direction), it adjusts how much light enters an eye's retina compared with another mode called 3D; or2) Switched back into regular observation mode where we see things that look slightly differently from what they were looking at beforehand instead of just showing them up sideways like traditional monitors. By measuring these changes over time, researchers have been able to determine which part of our brain has changed during vision training sessions.

Problems solved by technology

This patents discuss two technical problem addressed in these documents relates to evaluating the performance of displaying images accurately despite variations caused by factors like pixel size and numbering arrangement. Current methods have limitations due to their subjectivity and lack precision.
