摘要
失效元对红外焦平面阵列器件成像质量的影响较大。本文在给出失效元定义的基础上,对失效元的产生机理进行了分析,并给出了具体的失效元检测方法。基于DSP实现了红外图像的硬件处理系统并编写了失效元处理的软件程序,实现了失效元的自动检测和校正。实验结果表明,所设计的软硬件符合实时性、可靠性的要求,取得了较好的处理效果。
Invalid pixels have a great effect on the image quality of the infrared focal plane array device. In this paper, the definition of invalid pixel is presented firstly, and then the forming mechanism of invalid pixel is analyzed and the detecting methods for invalid pixel are discussed. With digital signal processing （DSP） chip, the hardware and software of infrared image processing system are designed for the purpose of auto-detection and correction of the invalid pixels. The experiment result indicates that the designed system get satisfied processing effect and the system meets the request of real-time and reliability.
