Abstract  The synchronous visual display of animal behavior signals provides an effective means to analyze and understand the characteristics of animal movement behaviors. In order to intuitively analyze the relationship between human motion posture and plantar contact force, a "behavior-force" synchronous visual display system was established. Firstly, LabVIEW software was used to realize the signal acquisition of multi-channel 3D force sensor based on UDP (user datagram protocol) and Kinect camera; secondly, a data synchronous processing method based on interpolation was proposed to realize the synchronous processing of motion posture signal and plantar force signal; then, a synchronous real-time visual virtual display system was constructed by using multi-threading technology to realize the synchronous real-time display of motion trajectory, motion posture and plantar contact force; finally, the experimental results verified that the display system had good real-time performance. The research result show that the "behavior-force" synchronous visual display system is an effective device to study the characteristics of animal movement behaviors.

“行为-力”同步可视化展示系统的开发

动物行为信号的同步可视化展示为分析和理解动物的运动行为特征提供了有效手段。为了便于直观分析人的运动姿态与脚底接触力的关系,搭建了“行为-力”同步可视化展示系统。首先,利用LabVIEW软件实现了基于UDP (user datagram protocol,用户数据报协议) 的多通道三维力传感器和Kinect相机的信号采集;其次,提出了一种基于插值的数据同步处理方法,实现了运动姿态信号与脚底受力信号的同步处理;然后,采用多线程技术构建了同步实时可视化的虚拟展示系统,实现了运动轨迹、运动姿态和脚底接触力的同步实时展示;最后,通过实验验证了该展示系统具有较好的实时性。研究结果表明,“行为-力”同步可视化展示系统是研究动物运动行为特征的有效装置。
