竞技体操现场技术姿态特征数据视觉感知系统可以实时准确地捕获和分析体操动作关键技术动作，对分析和指导运动员动作特征，提高训练和裁判评价水平提供数据和技术支撑。传统的竞技体操现场技术姿态特征数据视觉采集系统采用的是基于宽频带大功率数据感知的系统采集技术，对竞技体操这种技术特征要求复杂的运动项目适用性不好。提出一种基于可变增益控制放大的竞技体操现场技术姿态特征数据视觉感知系统设计技术，采用传感器自动采集竞技体操运动员人体的位置、角速度和旋转角度等信息，给出基于可变增益控制放大的竞技体操技术姿态特征提取的模型，实现系统硬件电路设计。系统实验结果表明，提取体操运动员在不同比赛时间节点上的姿态特征数据，具有较好的数据采集性能，能实时实现数据转换和调度，竞技体操现场技术姿态特征数据视觉重构效果较好，能准确和细节展示体操运动的技术性动作，性能稳定。

Gymnastics field technical attitude feature data visual perception system can capture and analyze the technical movement of gymnastics movement accurately, to analysis and guidance of athletes in action features, improve the training and the referee evaluation level to provide data and technical support. Using the traditional gymnastics field technical atti?tude characteristic data acquisition system is a system of visual data acquisition technology of broadband high power based on perception, sports complex requirements applicability is not good for gymnastics this technique characteristics. A vari?able gain control amplifier gymnastics field technical attitude feature data design technique based on visual perception sys?tem is proposed, using the sensor for automatic acquisition of competitive gymnastics athletes body position, angular veloci?ty and rotation angle information, given the variable gain control put gymnastics technology attitude feature large extraction based model, the realization of system hardware circuit design. System test results show that in different game time node gesture feature data extraction of gymnasts, with data acquisition performance is better, can be realized in real time data conversion and scheduling, better competitive gymnastics field technical attitude feature data visual reconstruction, it can accurately and display details of gymnastics skill action, it has stable performance.
