摘要
影像的几何质量影响着影像的定位精度。以光束法为平差模型,对高几何质量影像与高分辨率低几何质量影像的联合平差定位精度进行了实验与分析。研究结果表明:在高分辨率低几何质量的条带覆盖影像中加入单张高几何质量的影像进行联合平差,即可提高影像的定位精度;条带内影像的重叠度愈低,联合平差对影像定位精度的提高愈为明显。
The geometric quality affects the positioning accuracy of the image.The positioning accuracy of combined adjustment of high geometric quality image and high resolution and low geometric quality image on bundle adjustment were analyzed in experiment.Results show that the combined adjustment of a single high-geometric-quality image and a high-resolution low-geometric-quality strip image improved the image positioning accuracy.In addition,the lower the image overlap in the strip,the more obvious improvement of the image positioning accuracy by the combined adjustment.
