摘要
针对资源三号卫星姿态角常差导致的多光谱影像定位精度降低的问题,该文在构建多光谱影像严格几何定位模型的基础上,提出了运用罗德里格矩阵建立姿态角常差检校方法;根据少量地面控制点求出姿态角常差构成的偏置矩阵后,使影像定位精度得到显著提高。实验结果证明,该方法具有较好的应用价值。
Aiming at the problem that the positioning accuracy of ZY-3 satellite multispectral image is reduced by the constant angular errors, this paper established the calibration model of constant angular error by Rodriguez matrix on the basis of rigorous geometric model; once the matrix made up of the constant angular errors was eliminated using a few GCPs, the positioning accuracy could be significantly improved. Experimental results showed that this method had good application value.
