一种改进的卡尔曼滤波算法在非均匀校正中的应用

Application of an Improved Kalman Filtering Algorithm in Non-uniformity Correction

提出了一种改进的卡尔曼滤波算法,并将其应用于红外焦平面成像非均匀校正过程中。该算法合理的分配了传统卡尔曼滤波算法的计算量,克服了传统卡尔曼滤波算法计算量分配不均的不足,使该算法在相同的条件下不仅能更容易对非均匀校正算法进行实时处理,而且还能支持更高的分辨率。

An improved Kalman filter algorithm was suggested to use in the process of infrared focal plane non-uniformity. This method reasonably allocates the traditional Kalman Filter algorithm＇s computation, and changes the state of uneven computational distribution of the traditional Kalman filter algorithm. Thus, it is easier to deal with the non-uniformity correction in time and it can support a higher resolution.
