簇眼作为复眼的一种简单形式,对研究复眼特性有着重要的作用。针对簇眼对目标的大视场成像和目标定位与跟踪特点,设计了一种能够多通道同时捕获同一目标的簇眼结构,并使用基于Verilog语言的FPGA嵌入式系统对选取的大面元CMOS图像传感器的驱动时序进行了硬件描述和高速采集设计,实现了PC机对簇眼成像系统的实时数据获取。仿真和实验以及评估结果表明,基于FPGA的高速数据采集系统能满足簇眼对大范围目标的定位和高速目标的实时跟踪任务,从而为以后进一步研究大型复眼成像特点与目标定位和跟踪任务提供借鉴。
Cluster eyes,as a simple form of compound eye,play an important role to study the characteristics of compound eye.In this paper,aiming at the characteristics that cluster eyes can complete imaging task in large field to position and track some targets,a type of structure of cluster eyes is designed,which can capture the target in seven channels simultaneously.The hardware description and high-speed data acquisition design for driving time of CMOS image sensor of large imaging area using the embedded system based on FPGA and Verilog language are completed.The real-time data collecting system of cluster eyes is realized with PC.The results of simulation and experiment and evaluation show that the design of high-speed data collection system based on FPGA can meet the task of locating and tracking goal in large field with cluster eyes.And this can lay the foundations for the future study on the imaging characteristics of compound eye and locating and tracking goal with compound eye.
