A naked-eye 3D image design method for enhancing user experience

Abstract

The invention discloses a naked eye 3D image design method for improving user experience. The method comprises the steps of setting cameras in a virtual scene: placing a background camera at a scene start location specifically for obtaining a remote background image and then symmetrically placing N naked eye cameras at the left and right of the background camera in a circular arc arrangement mode; classifying objects in the virtual scene; setting rendering attributes of camera view images; synthesizing multiple naked eye camera images into a three-dimensional image; and establishing a naked eye 3D display image: outputting the finally synthesized three-dimensional image to a naked eye display screen and controlling all cameras as a whole to move in the scene, wherein a user can watch the naked eye image with good experience at any location in a visible area of the naked eye screen. The method has the advantages that the naked eye effect is clear, the background of the finally synthesized naked eye image is not fuzzy and the eye watching vertigo sensation at certain locations in the space can be reduced.

Description

technical field [0001] The invention relates to a naked-eye 3D image design method, in particular to a naked-eye 3D image design method that enhances user experience. Background technique [0002] Glasses-free 3D display technology has always been the frontier research field of human-computer interaction. Its basic principle is to allow the left and right eyes to see images with horizontal parallax, thereby simulating the situation of human eyes viewing external images in a real environment. The synthesis principle of naked-eye 3D images can be decomposed into three steps: 1. In the image acquisition stage, multiple cameras are used to simulate the scene pictures of different angles seen by human eyes, also known as multi-viewpoint images; 2. The pictures of multiple naked-eye cameras are synthesized into one Three-dimensional images are output and displayed on the naked-eye screen; 3. The image pixels on the naked-eye screen are projected in different directions by the grat...

Problems solved by technology

[0004] The above-mentioned existing solutions mostly use cameras placed horizontally and separately, and multiple cameras focus on a farther distance, but when viewing a nearby object, the human eye focuses on a closer position. The existing solutions have limited ability to express the naked-eye effect. When moving horizontally in the visible area, the picture will shake severely and cause dizziness; when multi-viewpoint images are fused into a stereoscopic image, the naked-eye effect of more viewpoints can be obtained by sequentially arranging the viewpoint images and cycled, but in one cycle In the transition stage from the end to the beginning of the next cycle, the parallax of the image received by the human eye is obviously too large, resulting in severe dizziness; in large-scale scene display occasions, if close focus is used to obtain the obvious naked-eye out-of-screen effect, the viewing angles of multiple cameras will be different. There is a large difference, resulting in too much difference in the distant view picture, resulting in blurred distant view
