Description

Naked eye 3D display mode switching control method, medium and system Technical Field The embodiment of the application relates to the technical field of image display, in particular to a method, a medium and a system for controlling switching of naked eye 3D display modes. Background The naked eye 3D display device refers to a display device that can be directly viewed with naked eyes without the need to achieve a 3D effect by wearing 3D glasses. The naked eye 3D display device generally adopts the technologies of a columnar prism, a slit grating and the like, the 3D effect is realized by utilizing the parallax characteristics of the left eye and the right eye, a stereoscopic image with space and depth can be obtained without any auxiliary equipment, and stronger visual impact is provided for people. Currently, naked eye 3D display equipment for single person watching exists in the market, the naked eye 3D display equipment mainly aims at single person watching to achieve 3D effects, and is called as two-viewpoint naked eye 3D display equipment, and meanwhile naked eye 3D display equipment for multiple persons watching simultaneously is also available, and can achieve 3D effects for multiple persons at different positions at the same time, and is called as multi-viewpoint naked eye 3D display equipment. The two naked eye 3D display devices have different characteristics and can be suitable for different application scenes, and have respective advantages and disadvantages. Although the two-viewpoint naked eye 3D display device can present a better 3D effect, a better 3D ornamental effect can only be provided for one viewer at the same time, so that multiple viewers cannot watch the 3D effect at the same time, and the multi-viewpoint naked eye 3D display device can provide that multiple viewers watch the 3D effect at the same time in a wider field, but the presented 3D effect is not ideal.
