摘要: 讨论了两点校正法的原理和算法,并针对高速CMOS图像传感器LUPA300,以FPGA作为系统硬件载体设计了非均匀性校正系统,进行实时非均匀性校正.实验结果表明,该系统能够有效地实时校正图像传感器的非均匀性,输出图像质量较高.Abstract: The principle and algorithm of two-point correction are discussed. And a non-uniformity correction systerm, whose hardware platform is FPGA, were designed. LUPA 300, was used in the system. Real-time non-uniformity correction was implemented in the system. The experimental result shows that system is effective to the real-time correction of the image sensor′s non-uniformity, and the system has a good image quality.
