Embodiment Construction

[0025] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The schematic embodiments of the present invention and their descriptions are used to explain the present invention and do not constitute Limitations on the Invention.

[0026] like Figure 1 to Figure 3 Shown, a kind of evaluation method of eyestrain comprises the following steps:

[0027] S1. Set up test subjects, and screen 88 test subjects without eye diseases and binocular visual function distortion through the inspection of vision testing equipment, and divide them into children experimental group, youth experimental group, adult experimental group, elderly experimental group, and children In the experimental group, the youth experimental group, the adult experimental group and the elderly experimental group, women accounted for the...

Abstract

The invention discloses a method for evaluation of visual fatigue. The method comprises the steps of forming viewers of a children experimental group, a young experimental group, an adult experimentalgroup, a senile experimental group; collecting the test objects' pre-viewing pupil diameter data and pre-viewing subjective evaluation data; collecting the viewers' in-viewing pupil diameter data andpost-viewing subjective evaluation data during the watching of four stereoscopic videos; determining a visual fatigue value according to the pre-viewing pupil diameter data, the in-viewing pupil diameter data, the pre-viewing subjective evaluation data and the post-viewing subjective evaluation data according to each experimental subject; adopting a statistical analysis method to analyze the visual fatigue value of each experimental subject, and forming pre-viewing and post-viewing visual fatigue analysis in aspects of different ages, different genders and different parallaxes and individuals. According to the method, the individual coverage of the visual fatigue evaluation is improved, the evaluation range is wider, and the blank of the analysis on influencing factors of visual fatigue such as gender difference, age difference and individual difference of viewers.

Description

technical field [0001] The invention belongs to the field of three-dimensional display technology and visual fatigue degree detection, and in particular relates to a visual fatigue degree evaluation method and evaluation system. Background technique [0002] In recent years, stereoscopic display technology has brought an immersive experience to human beings. However, compared with traditional flat-panel displays, viewing stereoscopic displays is more prone to visual fatigue symptoms such as eye pain, dizziness, and even nausea and vomiting, making it impossible to watch for a long time. For the continuous and stable development of stereoscopic display technology, it must be ensured that people's visual health will not be adversely affected when viewing, and at least have the same viewing comfort as traditional flat display. [0003] Stereoscopic viewing fatigue may occur in all age groups, genders, and races, but depending on the race, age, gender, vision and other factors ...
