Three-dimensional photographing method and system based on OpenGL ES (Open Graphics Library for Embedded System)

Abstract

The invention discloses a three-dimensional photographing method based on an OpenGL ES (Open Graphics Library for Embedded System). The three-dimensional photographing method comprises the following steps: S01, constructing a three-dimensional model geometric body by utilizing modeling software, and storing the three-dimensional model geometric body into a storage device of mobile equipment; S02, obtaining a video image by utilizing a camera of the mobile equipment; positioning the position of a human face through a human face identification and tracking method, so as to obtain video image data; S03, analyzing the three-dimensional model geometric body by utilizing a central processing unit of the mobile equipment, so as to obtain analyzed data; S04, drawing a three-dimensional model by utilizing the analyzed data through the OpenGL ES; S05, mixing the video image data and the three-dimensional model by utilizing an OpenGL ES mixing mode, and finally rendering a final scene with the three-dimensional model; S06, displaying the final scene to a user through a display device of the mobile equipment. According to the three-dimensional photographing method disclosed by the invention, a figure in a video and a virtual three-dimensional object are combined to be displayed together, so that the interestingness of photographing is increased, a responding speed is rapid and the rendering efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of graphics processing, and in particular relates to a three-dimensional photographing method and system based on OpenGL ES. Background technique [0002] At present, mobile phone photography has become the mainstream, and most people only need a mobile phone to take pictures when they go out. How to make mobile phone photography more interesting and fun has become people's needs beyond basic photography. [0003] At present, people often use various camera software to enrich and beautify photos, the most common of which is to add a foreground image to the image; and the existing foreground beautification methods mostly use the combination of two-dimensional images and characters in video images to achieve The purpose of beautifying the foreground of the image, but the two-dimensional image is relatively rigid, and the interesting performance is low; and the existing three-dimensional geometry rendering met...
