摘要
多通道融合成像是获取复杂目标图像信息的方法之一。但多通道成像存在图像融合、大容量数据缓存、数据高速传输等关键问题。就多通道成像的几个关键问题,在此提出一种基于FPGA+DSP的多通道图像获取系统硬件设计方法。该系统通过可编程逻辑器件FPGA控制图像采集时序,DSP TMS320DM648采用视频接口同时接收3路图像数据并进行必要的图像处理操作,经过DSP以太网控制接口与外部PHY芯片88E1111向计算机传输图像数据。结果表明,该设计集成度高,实用性强。
Multichannel fusion imaging is a method to acquire complex target information.However,the image fusion,massive data buffering and high-speed data transmission are most important in the multichannel imaging.A FPGA DSP-based method of the hardware design for multichannel image acquisition system is brought forward in this paper to solve those problems.The programmable logic device FPGA is adopted in this system to control the time sequence of image acquisition.DSP TMS320DM648 is used to receive three-channel image data simultaneously by its video interface and execute necessary image processing.The image data is transmitted through Ethernet control interface in DM648 and external PHY chip 88E1111 into computer.The result proves that the design has high integrability and practicality.
