Embodiment Construction

[0046] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0047] 1. The principle of stereo vision

[0048] The reason why human beings can observe the colorful scenes in the world is due to the existence of the eyes. The light enters the lens through the pupil and is imaged on the retina, and then the signal is sent to the brain by the optic nerve. After processing by the brain, the image is reproduced in the brain. Human eyes The physiological structure is very complex (such as figure 1 shown). Since the left and right eyes of people have a certain interpupillary distance, the angle and position of the line of sight projection are different when observing objects, that is, the imaging on the retina is different. The signal is sent to the brain through the optic nerve, and the brain processes the left and right information comprehensively to form a central eye pair. Imaging of observation points (such as ...

Abstract

The invention discloses a stereo video comfort evaluation method combining multiple parallaxes with motion, and belongs to the technical field of stereo video visual comfort evaluation. The method brings forward that three parallaxes of an object and the motion characteristic of the object are taken as important factors affecting stereo video comfort; four factors affecting the stereo video comfort are extracted, including an inter-frame substantial object parallax, an inter-frame correlation background parallax, an inter-frame parallax and a motion variable, a parallax graph is synthesized, a horizontal parallax is extracted, and a depth parallax is calculated; and a function relation between a subjective evaluation and the four major factors is established through combination of a depth perception theory and a least square fit method, a stereo video comfort evaluation model is obtained, and then the model is evaluated by use of a subjective evaluation method. According to the novel stereo video comfort evaluation method brought forward by the invention, the established model can be used to well simulate the subjective feeling of human eyes, and therefore, the method has great significance on research on the comfort of the human eyes in watching a stereo video.

Description

technical field [0001] The invention belongs to the technical field of visual comfort evaluation of stereoscopic video, and in particular relates to a method for evaluating visual comfort of stereoscopic video combined with binocular parallax and motion based on the characteristics of the human visual system. Background technique [0002] With the development of information technology, the public's pursuit of visual experience is getting higher and higher. In recent years, 3D movies have developed rapidly. Due to people's pursuit of visual feasts, more and more 3D movies are released in my country. In 2014, according to incomplete statistics, there were 50 domestic 3D movies released in addition to foreign 3D movies. Some people in the industry said that this year will It is the "3D year" of Chinese movies. If you look at the movies released recently, you can know that 3D movies have become the mainstream mode of watching movies. 3D stereoscopic video is becoming more and m...
