Embodiment Construction

[0031] The method of the present invention will be further described below in conjunction with the accompanying drawings.

[0032] As shown in Figure 1, it is a flow chart of the method of this embodiment. In the flow chart, the dashed box indicates the operation, and the solid line box indicates the result of the related operation.

[0033] The human body posture deformation technology based on video content of the present invention is mainly divided into the following steps:

[0034] Step 1. Customize the 3D human body model according to the video content;

[0035] Step 2. Project the customized 3D human pose (surface geometric model description) in step 1 on a 2D plane to generate a 2D model contour, which is represented by a set of sampling points;

[0036] a1. Use the 3D human body model customized in the previous step to describe the 3D pose data with a surface geometric model;

[0037] b1. Determine the viewing angle of the human body posture display from the given video, a...

Abstract

This invention relates to a human body posture deformation method based on video contents including: making a 3D human body model according to the video contents, projecting the 3D human body to generate a model skeleton, extracting the video human body profile information, setting up a point group corresponding relationship of video profile and model profile, transplanting the 2D skeleton in a model profile into the video profile to recover the 3D structure parameter in video, which is advantaged that demand on quality of video profile extraction is not high, which can be used in the 3D structure parameter recovery of motion object of known original 3D information.

Description

Technical field [0001] The present invention relates to the field of computer application technology, in particular to a method for body posture deformation based on video content. Background technique [0002] Obtaining three-dimensional human posture information from two-dimensional video is a hot and difficult problem in the fields of computer vision, pattern recognition, virtual reality, and intelligent human-machine interface. In this article, in accordance with convention, we uniformly abbreviate 2D as 2D, and abbreviate 3D as 3D. [0003] On the premise that the initial human pose 3D information is known, how to deform the initial pose according to the video content to obtain the corresponding 3D information in the video is one of the very important sub-problems. It not only has important research significance, but also has important research significance in the game. , Key-frame 3D animation, and 3D information acquisition based on instance data have broad application pro...
