摘　　要：在分析了红外焦平面阵列响应特性的基础上,提出了一种新的基于图像配准技术的“S”型曲线正交拟合算法,对红外焦平面阵列非均匀性进行自适应校正。仿真结果表明,该方法能有效地消除CCD像元响应不一致给图像带来的干扰,得到清晰的图像。Based on the analysis of response of IRFPA,a new adaptive non-uniformity correction technique is proposed based on video sequence registration and orthogonal least squares.With the scene estimates and the corresponding observed values through a given detector,an orthogonal curve-fitting procedure is used to estimate the individual detector offset and gains coefficients.Its efficiency and superiority are clarified by simulation.
