为了发展民族体育、弘扬民族文化,现设计一款民族体育教学中的特殊姿态校对视觉监控平台.该平台由视觉监控模块与特殊姿态校对模块构成.视觉监控模块负责进行特殊姿态数据的采集、量化与传导,讨论了该模块中的MFC监控架构、数据传导通信指令结构、主要硬件连接模式以及数据的高阶低通滤波方法.特殊姿态校对模块用于接收视觉监控模块传导出的特殊姿态量化数据,其利用Processing语言建立GUI优化数据结算空间,通过四元数结算方法完成特殊姿态量化数据向欧拉角的转化,根据欧拉角判定规则确定特殊姿态是否需要校对,并标记校对点.实验结果表明,所设计平台的滤波效果好,监控误差小.%In order to develop the national sports and promote the national culture,a special posture correction and visual monitoring platform for national sports teaching was designed. The platform is composed of visual monitoring module and special posture correction module. The visual monitoring module is used to acquire,quantify and transmit the special posture data. The MFC monitoring architecture,data conduction communication order structure,main hardware connection mode and data high-or-der low-pass filtering method in the visual monitoring module are discussed. The special posture correction module is used to re-ceive the special posture quantitative data transmitted by visual monitoring module. The Processing language is adopted to estab-lish the GUI to optimize the data settlement space. The special posture quantitative data is converted into the Euler angle by means of quarternion settlement method. According to the Euler angle judgment rules,it determines that the special posture should be corrected or not,and the corrected point is marked. The experimental results show that the designed platform has per-fect filtering effect and small monitoring error.
