基于DSP与FPGA的红外起伏背景估计系统

Estimation system of infrared clutter background based on DSP & FPGA

为了检测出起伏背景下的弱小目标,需要对红外图像进行背景抑制.针对红外起伏背景的统计特性,提出了一种线性、非线性的混合滤波算法,并从工程实用的角度给出了一个基于DSP与FPGA的并行硬件处理系统.结果表明,系统对红外起伏背景的估计效果良好并兼顾实时性.

The detection problem of point targets in IR images is a hot spot nowadays. In order to detect the weak targets from clutter background, the background suppression of IR image is necessary. This paper gives a linear and nonlinear combined filtering algorithm according to the infrared image＇ s statistical features. And a background estimation system is designed based on DSP and FPGA from the view of practical engineering. The results show that the system performs well in background estimation.
