摘要: 针对在野外像控点测量困难区域如何使用控制点快速纠正高分辨率卫星影像的问题,本文提出了基于稀少像控点的区域网平差方法,以实现在高精度、强现势性DEM的限制下,利用卫星影像快速制作1:10 000 DOM。并以阿拉善盟测区为例,进行了精度评价。结果表明,使用稀少像控点即可满足1:10 000 DOM的精度,可实现基于稀少控制点的遥感影像快速生产,有效地解决控制点难以获取时,造成DOM精度低且生产进度缓慢的问题。该方法能够为沙漠、林区等控制点缺乏地区提供一定的借鉴与参考。

Abstract: Aiming at the problem of using control points to correct high-resolution satellite remote sensing images in areas with difficult image control,a block adjustment method based on rare image control points is proposed,which uses high-precision DEM for constraints,and uses satellite images to quickly produce 1:10 000 DOM.In this study,the survey area of Alxa League is selected as the test area and the accuracy evaluation is performed.The results show that the accuracy of 1:10 000 DOM can be met by using rare image control points,which can realize the rapid production of remote sensing images based on rare control points,and can effectively solve the difficulty of obtaining control points.This method can greatly improve the production schedule due to DOM accuracy and schedule problems caused by the problem,and can provide reference for deserts,forest areas and other areas lacking control points.

Key words: high-resolution satellite image;RPC model;block adjustment;layout of image control points;accuracy analysis
