基于Camera Link的红外图像显示研究

Research on Real-time Infrared Imaging System Based on Cameralink

为红外相机设计了一套基于Camera Link的红外图像实时显示系统。红外探测器产生的模拟信号经模数转换后,由作为控制核心的FPGA进行处理,然后通过光纤实现远距离传输。接收端的FPGA将信号转换成Camera Link协议数据,再将它们传送给上位机的图像采集板卡进行采集和转换,最终通过上位机软件将其实时显示出来。

A real-time infrared image displaying system based on Camera Link is designed for an infrared camera. The analog signal from an infrared detector is converted to the digital one in an analog to digital converter. As a control core, the FPGA is used to process the signal and transmit it remotely via optical fibers. Then, the FPGA at the receiving terminal is used to convert the signal to the Camera Link protocol data and transmit it to the image collection card of the computer for data collection and conversion. Finally, the image data is displayed via the software in the computer.
