摘　　要：针对传统采集方式不灵活的特点设计了一种以FPGA为控制核心的高速图像采集系统.该系统选用线阵CCD作为图像信号采集芯片,采用FPGA产生与控制整个系统的时序,通过A/D对采集到的信号进行处理,最后通过以太网将信号传至上位机.此系统在图像数据的高速实时采集和处理上具有很大优势,且整体电路设计简单、直观、稳定、易修改,还具有设计灵活,传输速度快等特点.实验表明该系统可以有效地完成图像信号的采集,并且具备良好的稳定性与抗噪性.
The traditional image acquisition mode is not flexible.So this paper describes the design of a high speed image acquisition system with FPGA as the control core.This system adopts the linear array CCD as the image signal acquisition chip and uses FPGA to generate and control the whole system.A/D processes are used as the signal which is transmitted to PC via Ethernet.This system has great advantages in image high-speed real-time data acquisition and processing,and the design is flexible and the transmission speed is fast.The experiments show that the system can effectively complete the image signal acquisition,and have good stability and anti-noise.
