Embodiment Construction

[0026] The generation of binocular stereo vision requires that the left and right eyes receive two images containing different information at the same time, that is, the two images received by the left and right eyes contain different information of the same scene. In the present invention, these two images are called left-eye images and the right eye image.

[0027] When transmitting left and right eye images, the two types of images are usually interleaved and packaged, and transmitted serially. The order of transmission can be with the left frame (i.e. the first image for the left eye) as the first frame, and then sequentially interleaved ( L R L R ...). Or vice versa, use the right frame (i.e. the first image for the right eye) as the first frame and interleave sequentially ( R L R L ...). Usually the former is called positive phase transmission, and the latter is called negative phase transmission.

[0028] After receiving the interleaved image sequence in sequence, the...

Abstract

The invention discloses a three-dimensional double-projector automatic synchronization method and an automatic synchronization three-dimensional playing system. The method comprises the following steps: (1) setting identification data in front of a first frame of a positive film, wherein the identification data comprises at least one group of fundamental sequences, and each fundamental sequence comprises at least two images with different pixel values and the same visual effect; (2) image data is received, and the identification data is received; and (3) a phase position is checked automatically according to detected identification data. According to the invention, the playing operation of a three-dimensional film can be simplified and facilitated.

Description

[0001] technical field [0002] The invention relates to the technical field of three-dimensional image display, in particular to a method for automatically synchronizing the playback of 3D movies by two projectors. Background technique [0003] Three-dimensional (3D) image display technology is widely used in various fields (including movies, broadcasting, medical services, education, military, games, animation, etc.). And it is an important technology for the development of the next generation of three-dimensional display of movies. [0004] Because humans have binocular vision, they can perceive depth and distance in a three-dimensional world. Human eyes are separated horizontally by approximately 2.5 inches, and each eye perceives the world from a slightly different perspective. As a result, there will also be slight differences in the images projected on the retinas of each eye, a difference known as binocular parallax. As part of the human visual system, the brai...
