摘要
对复杂背景下大视场红外图像预处理的硬件实现做了探讨,结合FPGA在空间仪器上的应用,通过背景抑制及高通滤波、中值滤波,可以有效剔除脉冲干扰及大面积背景,极大地提高微弱目标的信噪比,为后续处理降低运算量。通过合适的算法组合,可以有效地促进滤波质量的改善及硬件实现结构的简化。最后给出实验结果及结论。
The implementation of complex background suppression is discussed for detecting infrared dim targets. After background suppressing and filtering, the intensity of target can be greatly improved, and complexi.ty of operation can be greatly reduced. The appropriate combination of algorithms can effectively promote the quality of filter and simplify the architecture of hardware. Finally, the results of experiment and the evaluation are given.
