高分卫星遥感影像相邻景之间精准匹配研究
|
摘要
针对高分卫星遥感影像间的空间定位不准、相邻匹配不佳等问题,选择国产高分一号卫星PMS传感器影像作为数据源,首先分析其原始相邻景影像重叠区域的匹配精度,再结合有理函数模型对影像进行正射校正,并总结其中选取控制点的个数对正射校正精度的影响程度,最后,在此基础上,通过区域网平差对正射校正后相邻景影像的匹配效果作进一步优化。结果表明:国产高分一号卫星PMS传感器影像原始相邻景影像之间的匹配精度较低,通过基于RPC优化的有理函数模型正射校正与区域网平差相结合的方法可以得到较好的匹配效果,相邻景影像之间的接边准确,河流、道路等地物没有明显的错位,相对几何精度较高,在一定程度上接近无缝接边。
In view of inaccurate spatial localization and poor adjacent matching among high-resolution satellite remote sensing images,the domestic satellite image of GF-1 PMS,selected as the data source,is used to analyze the matching accuracy of overlap region on the original adjacent scene image.The orthographical correction of the image is executed based on the rational function model,and the number of selected control points is summarized.Finally on this basis,the matching effect of the adjacent scene image is further optimized by the block adjustment.The result shows that the matching accuracy of the original adjacent scene images is low,and the matching effect is obtained by combining the orthographical correction based on RPC optimization with the block adjustment.Using this method,the edges of the adjacent scene images are accurate,and the rivers,roads and other objects have no obvious misalignment.The relative geometric precision is relatively high,and the seamless joints are close to a certain extent.The research result can provide a theoretical and technical preparation for the subsequent scale and industrialization of the GF satellite data.
