摘要:
 

非均匀性校正是提高红外图像质量的主要方法之一。针对传统的多点校正方法运算量大、实时性能差等缺点,提出多点实时压缩校正新方法,该方法将校正曲线相同或相似的不同探测单元归为一类,并将归类后的校正曲线的映射表存储在查找表中,校正过程中仅对查找表中的数据进行实时读取。实验结果表明:该算法计算量小、校正速度快,更加适合硬件实时实现。

Abstract:
 

Nonuniformity correction is one of the main methods that can improve the quality of infrared image. Aiming

at the problem of the large data storing and poor real-time capacity of traditional multi-point correction, a new

multi-points compressive correction method is proposed. Detector pixels with identical or similar calibration curve

will be classified as a class, and the mapping table of the categorized correction curves will be stored in a look-up

table. During the correction process, only the data in the look-up table is read in real-time. The experimental

results show the algorithm has less computation and requires less storage space of data, which is more suitable for

real-time hardware implementation.
