Embodiment 1

[0040] Such as figure 1 As shown, the embodiment of the present invention provides a 3D projection method, comprising the following steps:

[0041] The pre-shot parallax image is projected onto the angled plane formed by the ground plane and the vertical plane through a 3D projector to form a vertical plane projection and a ground plane projection.

[0042] The embodiment of the present invention combines the characteristics of the vertical plane projection on the basis of the ground plane projection to solve the problem of limited display height of the traditional three-dimensional ground projection.

[0043] The embodiment of the present invention is described in detail below:

[0044] The pre-taken parallax images are obtained in the following manner:

[0045] S11, such as Figure 4 As shown in , select the common face of the viewing volume of the pre-shooting model;

[0046] S12. According to the selected common surface of the viewing volume, the camera is used to sho...

Abstract

The invention provides a 3D projection method and relates to the technical field of three-dimensional projection display. In this method, the pre-shot parallax image is projected onto an angled plane composed of a ground plane and a vertical plane through a 3D projector, forming a vertical plane projection and a ground plane projection. The invention combines the characteristics of the vertical plane projection and solves the problem of limited display height of the traditional three-dimensional projection on the ground.

Description

technical field [0001] The invention relates to the technical field of three-dimensional projection display, in particular to a 3D projection method. Background technique [0002] Three-dimensional display is a new research hotspot with the rapid development of computer graphics and image technology. The relatively mature 3D display technology currently on the market is mainly based on the principle of binocular parallax of the human eye. Due to the distance between the two eyes of a human being (6.5cm on average), the relative positions of the left and right eyes are different for the same scene. This creates binocular parallax, where the left and right eyes see different images. When the left and right eyes of a person respectively receive the left and right images with a certain horizontal parallax, the person can obtain the depth information of the image. When a 3D projector is used to project two images with horizontal parallax onto the ground, people can feel that th...
