[0024] Please refer to figure 1 , which shows a method flowchart of a three-dimensional image display method provided by an embodiment of the present invention. The method may be a three-dimensional image display process performed by a three-dimensional image display device; the three-dimensional image display device may be equipment such as a television, a computer, etc., and the three-dimensional image display method may include the following steps 101-107:

[0025] Step 101, controlling the operation of a virtual camera in a 3D scene to generate and display a current 3D image.

[0026] The 3D program installed on the 3D display device can control the 3D virtual camera to operate in the original image scene, and then generate and display the current 3D image through various processing, such as rendering. The source of the original image can be an image calculated in real time by a 3D program (such as a 3D game, etc.).

Abstract

The embodiment of the invention discloses a method and a device for displaying a three-dimensional image, and belongs to the field of display. The method for displaying the three-dimensional image comprises the following steps: controlling a virtual camera on a three-dimensional scene to work so as to generate and display a current three-dimensional image; when motion of a user observation point is detected, obtaining motion information of the user observation point, and obtaining current motion information of the virtual camera, and generating new motion information of the virtual camera according to the current motion information of the virtual camera and the obtained motion information of the user observation point; controlling the virtual camera to work according to the new motion information of the virtual camera so as to generate and display a new three-dimensional image. According to the method and the device for displaying the three-dimensional image, the three-dimensional image dynamically adaptive to user motion is generated in a human-computer interaction manner, so that the motion of the virtual camera on the three-dimensional scene along with the motion of the user can be automatically realized in the displaying process of the three-dimensional image, and the three-dimensional image more similar to the real world is realized.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a three-dimensional image display method and device. Background technique [0002] At present, the new generation of 3D display technology including 3D movies and 3D TV is the future development trend, and has extremely important research value and huge market prospects in daily family life and commercial fields. Three-dimensional display is the effect produced by people observing the natural world with both eyes. Due to the horizontal distance difference between the two eyes (about 6.5 cm on average for adults), when observing the same object, the two eyes will obtain two different images, which is called aberration, and then the brain Stereoscopic perception is obtained by analyzing aberrations. The currently popular 3D image display processes all utilize this principle. [0003] Three-dimensional image display methods can be mainly divided into two types: the first method i...
