摘要：

红外焦平面阵列(IRFPA)被广泛用于各个领域中。由于红外视频信号针对不同领域的不同需求,后续处理算法复杂,需有效地提高其实时性能。因此文中以TMS320DM642高速DSP处理器为主要元件,构建了红外图像信号采集和处理系统。分析了红外视频信号采集工作原理,研究了提高信号处理速度的方法。实验结果表明,图像采集和处理系统运行稳定可靠,在该系统上实现的图像放大算法满足了实时性要求,为信号的后续精细化处理奠定了基础。

Abstract:

The Infrared Focal Plane Array is widely used in every field.The infrared video signal has different needs in different areas,which leads to the complexity of the post-processing algorithm.The real-time performance needs to be effectively improved.To improve the system performance,this paper builds an infrared image acquisition and processing system based on TMS320DM642,analyzes the working principle of the infrared image acquisition and studies the way of improving the speed of signal processing.Experiment results show that the system is stable and reliable,and the image magnification algorithm based on the system meets the real-time requirement.The success of this experiment lays a foundation for the subsequent signal processing.
