Image processing method and system for preventing naked eye 3D viewing dizziness and display device

Abstract

The invention relates to an image processing method and system for preventing naked eye 3D viewing dizziness and a display device. The method comprises the following steps: caching source 3D video image data; according to the source 3D video image data, acquiring depth image data; detecting a pupil distance of a viewer, and acquiring an actual pupil distance value; calculating updated depth image data; according to the updated depth image data, generating video data streams of a left camera and a right camera by taking positions of the virtual left camera and virtual right camera corresponding to a set spacing as a viewing angle; and outputting the video data streams of the left camera and the right camera to a naked eye 3D display screen to obtain a 3D display effect. Result data of a 3D display image can be adjusted according to an eye pupil distance of the viewer in real time, so that the outputted 3D display image can be matched with the pupil distance of the viewer in real time, the 3D display effect can be changed along with the pupil distance of the viewer, the dizziness generated when viewing 3D display by naked eyes can be avoided, and the time of viewing 3D by the naked eyes can be prolonged, which is beneficial to large range of popularization and application of naked eye 3D technical products. The above processing method and system can be applied to mobile phones, various computers, advertising machines, liquid crystal display video walls, medical display equipment and other 3D display products.

Description

technical field [0001] The present invention relates to the improvement of naked-eye 3D display technology, in particular to an image processing method and system for preventing dizziness in naked-eye 3D viewing and a naked-eye 3D display device. 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 started small-scale commercial application. Mass consumers don't have much exposure. 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 applied to specific things that need t...

Problems solved by technology

[0003] However, in the current 3D display technology, when image processing is used for 3D display, no matter it is based on technologies such as 9 viewpoint differences to display stereoscopic images, since naked-eye 3D does not have the parallax adjustment of glasses equipment, and the distance between the pupils of each person's eyes The distances are different, so in the acquisition and reproduction of stereoscopic display scenes (images and videos), the theoretical pupillary distance is used to display stereoscopic images, because when different people see stereoscopic images with the same display effect, they will be very different. Unsuitable, 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, so that the display technology of naked-eye 3D cannot be commercially promoted on a large scale
