球类目标运动路径自动捕捉系统设计

Design of automatic capture system for ball target motion path

针对加速度传感器捕捉系统在轮廓波域边缘捕捉时易受到噪声干扰,导致捕捉路径与实际运动路径坐标点不一致问题,设计基于数据同步协议的球类目标运动路径自动捕捉系统。采用多级分布式控制模式设计DSP控制器,通过TMS320F240XDS管道改善指令执行速度;采用正交陀螺仪在X,Y,Z轴上测量角速度,通过数据采集模块和数据存储模块完成运动捕捉模块设计。设计数据同步协议,以TDMA形式与每个中继节点进行通信;采用Radon尺度变换方法对数据进行降噪处理,设计球类运动路径自动捕捉流程。实验结果表明,该系统与实际运动路径坐标点一致,捕捉效果良好。

Based on the problem that the acceleration sensor capture system is easy to be disturbed by noise when capturing the edge of the contourlet domain,which leads to the inconsistency between the capture path and the actual motion path.Therefore,an automatic path capturing system for ball targets based on data synchronization protocol is proposed.The DSP controller is designed by using multi-level distributed control mode.The TMS320F240XDS pipeline is used to improve the instruction execution speed.The angular velocity is measured on the X,Y,Z axes by the orthogonal gyroscope.The motion capture module is designed by data acquisition module and data storage module.The data synchronization protocol is designed to communicate with each relay node in the form of TDMA.Radon scale transformation method is used to denoise the data,and the automatic path capture process of ball games is designed.The experiment results show that the system is consistent with the actual motion path coordinates,and the capture effect is good.
