Method for creating object-oriented customized three-dimensional human body model

Abstract

The invention discloses a method for creating an object-oriented customized three-dimensional human body model. The method comprises the following steps: acquiring images of a human body object at the same moment at different angles by a plurality of synchronization cameras and rebuilding a three-dimensional feature point cloud of a human body from the images by adopting a three-dimensional rebuilding method; matching a simple three-dimensional human body model onto the three-dimensional feature point cloud by adopting a pose estimation method on the basis of a model; according to a matching result of the three-dimensional human body model and the point cloud, detecting all main human body positions and joint positions and dividing the human body to form all of the part; according to the detected human body positions and joint positions, generating a human body skeleton for driving the human body model; regulating and amending the joint positions. The method for creating the object-oriented customized three-dimensional human body model, disclosed by the invention, solves the problems of shortage of matching degree and adaptability of an existing three-dimensional human body model on the specific human body object and can create the three-dimensional human body model completely coincided with the feature dimension of the human body object.

Description

technical field [0001] The invention relates to the field of electronic information science and technology, in particular to an object-oriented customized three-dimensional human body model creation method. Background technique [0002] Three-dimensional human body models are used in computer animation, games, human motion tracking, motion capture and other fields. [0003] In the field of computer vision, model-based 3D human motion tracking is a hotspot of current research. Generally, there are two basic architectures for model-based 3D human motion tracking: the first is a "top-down" architecture, which creates a 3D human body model and initializes the human body model in the first frame, including initializing the human body. The pose and size of the model make the human body model match the human body object; in the tracking process, one or more predictions of the human body in the current frame are obtained by using the tracking results of the previous frame and the c...

Problems solved by technology

[0005] The purpose of the present invention is to address the deficiencies of the above-mentioned prior art, and propose a method for creating an object-oriented customized three-dimensional human body model. When the method is aimed at obtaining the three-dimensional reconstruction data of the human body, the human body model is directly created from the reconstruction data, and the obtained human body model It has a high degree of fit with human objects, and can solve the problem of lack of matching and adaptability to specific human objects in existing 3D human models. The method has high efficiency and good feasibility
