在研究了CMOS图像传感器和flash存储器的工作原理的基础上,阐述了以FPGA为控制核心的图像采集和存储系统结构,设计了在图像采集和存储系统中的FPGA控制模块,用USB通讯模块实现了采集存储系统和计算机之间的数据传输,满足了系统对回放的存储图像不丢帧的要求。经实际检验,较好地满足了实验要求。
On the basis of studying the CMOS Image sensor and flash's principle,The structure is discribled in this paple,including Image acquisition and storage system with FPGA control.The module of FPGA control is designed in the system of Image acquisition and storage.The module of USB realizes the data communacation between the Image acquisition and storage system and the computer,and this scheme meets the need that system's storage image is not lost.Practical application shows this scheme is reasonable.
