Problems solved by technology

Such an operation method is cumbersome and inefficient; there is no prompt information for the connection between rigid bodies, and errors are prone to occur during labeling. At the same time, due to errors during reconstruction, it cannot be guaranteed that all feature points participating in labeling are correctly reconstructed. Feature points

Abstract

The invention relates to a method and a system for realizing a human chain structure model. The method comprises the following steps of: 1, extracting a key frame sequence of a three-dimensional characteristic point sequence of human motion; and 2, obtaining candidate combination of the human chain structure model according to the absolute orientation algorithm and rigid body distance constraint, and selecting correctly established human chain structure model from the candidate combination by a user. The method and the system for realizing the human chain structure model can establish a model of any chain structure individual, and also provide good prior model and basis for the motion tracking while simplifying the model establishment process. The human structure model which is directly labeled can be obtained without complex manual operation by presetting the three-dimensional characteristic point sequence of the human motion; and the initialization work of the human structure model is simplified during the motion tracking. The established human structure model can be directly applied to the motion tracking and is convenient and quick.

Description

technical field [0001] The invention relates to the fields of computer vision and pattern recognition, in particular to a method and system for realizing a chain structure model of a human body. Background technique [0002] The establishment of the chain structure model of the human body embodies the shape, size and connection relationship of each part of the human body, and it contains the prior knowledge of the physiological structure of the human body. In the human motion analysis with feature points, to describe the motion of the object, it is necessary to track the feature points of the moving object, calculate the position of the joint center, and drive the bone model. For different moving individuals, it is necessary to specify the names and positions of the reconstructed 3D feature points according to the topological structure of the human body model, and establish a human chain model that meets the requirements, so as to continue to complete the tracking task and d...
