The Application Research of 3D Simulation Modeling Technology in the Sports Teaching

Abstract

With the current development of information technology in sports training in computer-aided training has become increasingly common to achieve a sports training video feedback analysis system, through pattern recognition, image processing, video analysis and other modern computer technology information processing technology the sports training and computer application technology, computer vision from the perspective of analysis and study of sports. Based on three-dimensional modeling of motion simulation can help sports training, sports science analysis methods to achieve experiential training methods from stylized transition, leading to faster and more effectively improve the level of sports training and athletic performance. The use of a simplified model of the human skeleton, in conjunction with specific prior knowledge of sports action, resulting in partial attitude information athletes. Design and implementation of information technology systems will be combined with physical training, can give a variety of auxiliary information sports action, and can effectively assist coaches and athletes to improve training efficiency. Introduction Sports simulation system can be further combined sports full experience of sports action for analysis, to identify the type of action, extracting the outline of athletes, athletes’ posture preliminary analysis. Real-time processing part of the system, mainly to obtain prospects in part by video motion background separation technology to remove all kinds of noise, obtained in which part of the video player [1-2]. Then centroid approximate center of gravity, the center of gravity trajectory fit athlete, combined with camera calibration parameters in advance, calculate important parameters coaches and athletes concerned, the use of voice and on-screen display a variety of ways, instant feedback to coaches and athlete. The system also can be for some sports action for further analysis and processing [3]. Due to the development of computer technology, increasing data storage capacity and rapid decline in prices, resulting in data storage athletes is a quick and cheap. How to use these large amounts of data, in-depth analysis of technical movement essentials, athletes, and coaches training provided useful reference information [4]. Therefore, the application of modern computer technology has become the most important tools to improve the level of competition. An important reason for the majority of sports projects did not successfully develop simulation training system is collaborative approach sports training coaches and athletes and computer software developers is not reasonable, we need to study the characteristics of professional sports training and computer simulations to develop the simulation system according to Sports Training Most problems have developed simulation software accuracy, practical aspects;; model; many coaches do not fully understand the role of simulation training software that has been developed is difficult to truly meet the needs of end users, software development needs analysis done early Did not do well. . Human joint model overview The human skeleton model is the base model of the human body. Important because it contains the joint three-dimensional location information, it can better represent the human information. 4th National Conference on Electrical, Electronics and Computer Engineering (NCEECE 2015) © 2016. The authors Published by Atlantis Press 1680 Artificial joint model used in Figure 1, which contains a total of 23 joints, the root of the waist. Because doing so would cause motion capture coordinate data is based on the world coordinate system, we first will coordinate every action will be converted to the root of the coordinate origin of the world coordinate system, in order to make action sequences absolute position data regardless of the body [5-6].
