基于FPGA的多功能红外图像源系统设计

Design of Multi-function Infrared Image Source System Based on FPGA

提出了一种基于现场可编程门阵列(FPGA)的多功能红外图像源系统的设计方案。信号源系统在降低图像系统的研制成本、缩短研制周期和提高研制质量方面具有重要的作用。以A ltera公司的EP2S60-FPGA作为硬件架构,设计了一种红外图像源系统。该系统通过数据压缩、数据扩展及插值、制式转换等方法实现红外图像数字视频及模拟视频的双通路输出,用于二次开发和图像显示。所设计的红外图像源系统具有参数易调与小尺寸低功耗等特点,可方便下载现场红外图像信号和实时输入CCD图像信号,并按照红外图像格式输出,从而为红外图像信号处理器提供输入激励。

A multi-function infrared image source system is designed based on FPGA. The signal source system has important use in reducing cost,shortening develop period and advancing develop quality. By using the EP2S60-FPGA of Alter Co. as the hardware architecture, an infrared image source system is designed. This system can carry out double outputs that are infrared digital image video output and infrared analog image video output by using data-compress, data-expand,value-insert and format-convert methods. It can download infrared image signal or input CCD real-time image signal conveniently and output in infrared image format. It can be used as the input of infrared image signal processor.
