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 for automatically establishing a human body chain structure model and a system thereof. The method comprises the following steps: step 1. determining a topology model of a human body chain structure; step 2. acquiring a three dimensional characteristic point sequence of human motion; step 3. automatically dividing each rigid body in the three dimensional characteristic point sequence and the characteristic points included in the each rigid body; step 4. performing name determination to the characteristic points included in the each rigid body according to thetopology model and establishing the human body chain structure model. By using the method of the invention, the human body chain structure model, which is suitable for tracking the motion, can be correctly and conveniently obtained from the acquired three dimensional characteristic point motion data sequence.

Description

technical field [0001] The invention relates to the fields of computer vision and pattern recognition, in particular to a method and system for automatically establishing 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 chain structure model of the human body that meets the requirements, so as to conti...
