本文在分析现行各种非均匀校正算法优缺点的基础上 ,根据红外焦平面器件探测单元响应曲线特点和神经网络理论 ,提出一种新的非均匀校正方法——“S”曲线模型算法。该算法能同时校正焦平面器件的非均匀性和非线性 ,并且具有动态范围大、存贮容量小和校正精度高等优点。 In this paper, based on the analysis of the advantages and disadvantages of the existing non-uniform correction algorithms, a new non-uniform correction method - “S” curve model algorithm is proposed according to the characteristics of the response curve of the infrared focal plane device detection unit and the neural network theory. The algorithm can correct the inhomogeneity and nonlinearity of the focal plane device at the same time, and has the advantages of large dynamic range, small storage capacity and high accuracy of correction.
