A method and system for detecting visual comfort of stereoscopic display with different viewing angles and parallax

Abstract

The invention discloses a stereoscopic display visual comfort detection method and system with different watch angles and parallaxes. The method includes: 1)respectively playing stereoscopic display resources by selecting various horizontal watch angles, and recording the watch comfort for a viewer during watching of different parallax resources with different watch angles; 2) performing non-linear regression of a cubic function by regarding different horizontal watch angles alpha as the independent variable and regarding the visual comfort C as the dependent variable in the condition of different parallax resources beta, and obtaining a non-linear relation model C[beta]=w[beta], 1+w[beta], 2*a+w[beta], 3*a<2>+w[beta], 4*a<3>, wherein C[beta] represents the visual comfort of different parallax resources beta, and alpha represents the horizontal watch angle; and 4) selecting the corresponding non-linear relation model according to the parallax beta of a to-be-detected stereoscopic display resource, inputting the watch angle of the to-be-detected stereoscopic display resource to the selected non-linear relation model, and obtaining the visual comfort of the to-be-detected stereoscopic display resource.

Description

technical field [0001] The invention belongs to the field of three-dimensional display evaluation, and in particular relates to a visual comfort detection method and system for viewing stereoscopic displays with different parallax from different horizontal angles. Background technique [0002] With the advancement of science and technology, people's quality of life is getting higher and higher, and there is also a higher demand for watching TV, movies and video games. Along with the demand, 3D stereoscopic display technology has begun to be widely used. However, while the 3D stereoscopic display technology is widely used, it also brings some unavoidable negative effects, such as long-time viewing, which may cause some discomfort symptoms such as dizziness, nausea, vomiting, and fatigue. The main reason for this situation is the conflict between the stereoscopic display technology and the visual imaging mechanism of the human eye. The stereoscopic display content has differe...

Problems solved by technology

Most of the experiments now choose to use subjective detection, because many objective measurements are not only complicated and expensive, but also have a great impact on the viewer's viewing experience during the measurement process, and at the same time require cumbersome processes for data processing in the later stage

At the same time, there are no standards for the selection of objective parameters and their thresholds for reflecting the degree of subjective discomfort.
