摘要
本文从DMC成像特征分析了引起拼接影像变形的系统误差,然后对带附加参数自检校平差模型进行探讨。利用位于河南的嵩山摄影测量遥感定标与综合实验场获取的不同航高DMC数据,比较了在不同航线结构和控制点条件下对求解拼接影像几何变形参数的影响。实验结果表明,3种航线结构自检校都达到了相同的精度,使用2条平行航带可以取代完整航线结构用于日常检校。
The imaging characteristics of DMC image were analyzed with systematic errors for virtual image. Then the additional parameters in block adjustment with self-calibration were discussed. In the experimental part, DMC images were used with different flight heights in Songshan testsite to compare the obtained values of the additional parameters of difference in the strip structure and the distribution of control points. The experimental results showed that there was no discernable loss of accuracy for the seff-calibration method in the strip structure. The two parallel strips could replace the comprehensive strip structure for daily calibration.
