Interpupillary distance measuring method and system for 3D display system and display device

Abstract

The invention relates to an interpupillary distance measuring method and system for a 3D display system and a display device. The method comprises the following steps: acquiring image data containing facial features of an observer, obtaining the interpupillary distance value of a human eye image, converting the interpupillary distance value of the human eye image into the actual interpupillary distance value under a three dimension space system according to a real space size factor result, and outputting the actual interpupillary distance value. The interpupillary distance value of the observer can be automatically obtained in real time, and real-time performance in interpupillary distance detection can be improved. Based on the interpupillary distance value which is automatically obtained in real time, a data source of 3D frames can be automatically adjusted according to the interpupillary distance of the observer, and therefore 3D display effects can change along with the interpupillary distance of the observer; the observer can be prevented from vertiginous sensation when watching 3D displays with naked eyes, the observer can watch the 3D displays with the naked eyes for a longer time, and large-scale popularization and application of naked eye 3D technology products can be benefited. The said method and the said system can be applied to devices capable of image processing, such as mobile phones, all kinds of computers, advertisement machines, liquid crystal splicing screen walls, medical display equipment and the like.

Description

Technical field [0001] The present invention relates to the improvement of naked-eye 3D display technology, in particular to a method and system for measuring human eye pupil distance and a naked-eye 3D display device applying the measurement technology. Background technique [0002] The research and development of naked-eye 3D technology is divided into two directions, one is the research and development of hardware equipment, and the other is the research and development of display content processing. The second type has already begun small-scale commercial applications. Not much contact with mass consumers. The biggest advantage of naked-eye 3D technology is that it gets rid of the shackles of glasses, but there are still many shortcomings in terms of resolution, viewing angle, and viewing distance. Of course, in recent years, a simpler naked-eye 3D imaging technology has emerged in China, which is the second technology. It is directly used on specific things that need to s...

Problems solved by technology

[0003] However, in the current 3D display technology, when image processing is used for 3D display, whether it is based on technologies such as 9-point difference to display stereoscopic images, or other methods, since naked-eye 3D does not have the parallax adjustment of glasses equipment, and each person's eyes The distance between pupils is different, so in the acquisition and reproduction of stereoscopic display scenes (images and videos), the theoretical interpupillary distance is used to display stereoscopic images, because when different people see stereoscopic images with the same display effect , it will be very unsuitable, and some viewers will feel dizzy after watching for a certain period of time, and have obvious dizziness, so they cannot watch the 3D imaging effect with naked eyes for a long time, which makes the display technology of naked-eye 3D unable to carry out commercial promotion on a large scale
