利用LVRT(LabVIEW real-time)实时操作系统部署高速图像处理算法,并结合FPGA(field programmable gate array)技术,建立一种面向动物行为学实验的高速实时检测跟踪与刺激系统,对连续帧图像做到确定性输出,实现各个不同动物行为学实验场景下的运动目标高速检测跟踪及刺激。应用实验表明,在100 fps采集速率下,该系统具有较好的实时性和稳定性,系统从目标检测到刺激反馈信号输出这一整个过程的处理时间稳定为10 ms,执行时间的平均相对误差较传统系统降低了15%,同时,在线分析完成了目标检测、运动轨迹、划分区域内小鼠行为特征分析等功能,离线分析生成运动轨迹热图,大大提升实验效率。
The real-time operating system-LabVIEW real-time is used to deploy high-speed image processing algorithm, and combining with FPGA(field programmable gate array) technology, a high-speed real-time detection tracking and stimulation system facing to animal behavioristics experiments is established. The definitive output of continuous frame image is achieved, and the motion target high-speed detection tracking and stimulation in different animal behavioristics experiment scenarios are realized. The application experiments show that the system has good real-time and stability under the acquisition rate of 100 fps, the processing time of the whole process from target detecting to stimulus feedback signal output is 10 ms stably, the average relative error of the execution time is reduced by 15% compared with that of the traditional system. With online analysis the functions of target detection, motion track, mouse behavioral characteristic analysis in the dividing area are completed, and with offline analysis the motion track heat map is generated, which greatly improves the experiment efficiency.
