Embodiment Construction

[0010] This specific implementation adopts the following technical solutions: Its modeling method is: 1. Install sensors on each joint of the human body, and connect each sensor with the detection host; 2. Perform motion capture through the sensor array installed at each joint, and capture the video The middle data points are fitted to form a spline curve; 3. Reuse the smoothing of the curve and optimize the algorithm to process the edge contour curve; 4. According to the hierarchical structure of the joints of the human body, the limbs are abstracted into simple rigid geometric entities, and Use VRML to construct samples of human skeleton models; 5. The skeleton models of each limb can be obtained through transformation based on this sample model.

[0011] The principle of this specific embodiment is: the detection host adopts the joint single-point recognition method, the limb multi-point recognition technology and the new method of landmark image processing. When the human body...

Abstract

The invention discloses a human body skeleton modeling method, and relates to the technical field of human body skeleton modeling. The modeling method comprises the steps that sensors are installed on the human body joints and connected with a detecting host; action catching is carried out through the sensor arrays installed on the joints, fitting is carried out on data points in a video to form a spline; the edge contour curve is processed through a smooth and optimization algorithm of the spline; the limbs are abstracted into simple rigid geometric solids according to the layer structure of the joint connecting bodies of the human body, and a sample of a human body skeleton model is established through a VRML; skeleton models of the limbs can be obtained by changing the sample model. The human body skeleton features are analyzed and recognized through the action recognizing technology based on the video, operation is easy, the quick and accurate modeling purpose can be achieved, and online analyzing is achieved.

Description

[0001] Technical field: [0002] The invention relates to the technical field of human bone modeling, in particular to a human bone modeling method. Background technique: [0003] In the process of human interaction, vision is the most important information, which can help people quickly obtain some key features and facts. It has a wide range of application value in the fields of smart video surveillance, abnormal motion recognition, human-computer interaction and virtual technology. At the current stage, the current research on human motion recognition mainly focuses on the structural analysis of the moving human body and the tracking of human motion targets. [0004] The analysis and recognition of human actions is one of the important topics of current research in the fields of computer vision and image recognition. Human actions are composed of continuous static postures, because the action itself has quite complex high-dimensional information in space and time, and the act...
