The current sports feedback system has high application value and is widely used in physical education courses, but it has problems such as large feedback error, long response time, and incomplete data, leading to poor effect of sports feedback system. In order to improve the effectiveness of sports feedback system, a sports feedback system based on video digital processing is designed. By constructing the overall architecture of video digital sports feedback system, the positioning module, interface module, power supply circuit module, sampling module, input module, signal extraction module, and video digital processing module are designed. Using information communication mechanism, TCP/IP network protocol, serial communication, and shared memory to improve video digital processing, experimental results show that the designed system has good error convergence of 0.1, short response time of 32 s, and high data integrity of 94%, which has strong practicability.
当前的运动反馈系统具有很高的应用价值,广泛应用于体育课程中,但存在反馈误差大、响应时间长、数据不完整等问题,导致运动反馈系统效果不佳。为了提高运动反馈系统的效果,设计了一种基于视频数字处理的运动反馈系统。通过构建视频数字运动反馈系统的总体架构,设计了定位模块、接口模块、电源电路模块、采样模块、输入模块、信号提取模块和视频数字处理模块。利用信息通信机制、TCP/IP 网络协议、串行通信和共享内存来提高视频数字处理的性能。实验结果表明,所设计的系统具有良好的 0.1 误差收敛性、32s 的短响应时间和 94%的高数据完整性,具有很强的实用性。
