一种负荷可调节的运动追踪系统设计

Design of an adjustable load motion tracking system

针对人体运动目标的实时监控,文中设计了一种负荷可调节的运动追踪系统。首先在系统软件设计时简要划分图像采集、目标检测、目标标定、目标追踪四个步骤,并预设两个配置点,配置点前的任务由嵌入式系统完成,其余任务由计算机完成。追踪系统通过自主调节配置点,使嵌入式系统和计算机充分发挥各自优势达到均匀负荷,并同时将三帧图像拼接成宽视野监控图,实现对目标的续接追踪。实验结果表明该追踪系统可以实现多目标宽视野的追踪,提高了系统资源的利用率和系统性能,增强了实时性和稳定性。

In view of real time monitoring for human motion target,an adjustable motion tracking system was designed in this paper. First of all,during designing of system software,four steps were divided up brifly as image acquiring,target detecting,target marking,target tracking,and two configuration points were presetted, the task before configuration points was completed by the embedded system, the remaining tasks are completed by the computer. By adjusting configuration points independently,the tracking system made the embedded system and the computer gives out full play to their respective advantages to achieve even load,then stitched three frames of images at the same time into a wide filed monitoring picture,so as to achieve targets consecutive tracking. The experimental results showed that the tracking system can achieve multi-objects wide field tracking,the utilization of system resources and system performance were improved,the real time and stability were also enhanced.
