摘要
针对当前影像几何定位时变系统误差难以补偿的问题, 提出一种基于傅里叶级数模型的时变系统误差地面补偿方法, 并采用几何定标场的数字正射影像图/数字高程模型数据进行精度验证。分析了2014年12月发射的遥感二十六号卫星的数据, 结果表明, 设计的时变系统误差地面补偿模型可以有效提高影像在无控点条件下的几何定位精度, 且补偿后的影像几何定位精度可以提高约40%。
Abstract
According to current problem that the time-varying systematic error of image geometric positioning is difficult to be compensated, an algorithm based on Fourier series model is proposed to achieve the on ground compensation of time-varying systematic error. The digital orthophoto map/digital elevation model reference data of geometric calibration field is used for accuracy verification. The data of Yaogan-26 satellite launched in December 2014 is analyzed, the results show that, this designed on ground compensation model of time-varying systematic error can effectively improve the image geometric accuracy under no ground control points, and the image geometric positioning accuracy after compensation can be increased about 40%.
