摘　　要：第三次全国国土调查要求生产覆盖全国分辨率了优于1.0 m的高分辨率卫星正射影像底图,西部控制资料缺乏区域高分辨率卫星影像的几何定向是需要解决的难题。针对这个问题,介绍了一种基于立体和非立体影像协同处理的高分辨率遥感卫星影像几何平差方法和技术流程,该方法利用高分辨率测绘立体卫星影像对在区域网平差构网中的优势,解决了非立体高分辨率卫星影像平差所需的控制资源,实现了在无控(稀少控制)条件下非立体高分辨率卫星影像的几何定向。工程实践结果表明,该技术方法和流程可行,数据处理精度达到第三次全国国土调查正射影像生产相关技术规范对于几何精度的要求,解决了三调西部控制困难区域高分辨率卫星影像的几何定位难题,保障了三调正射影像生产任务的顺利进行。Third national land survey required the productions of high-resolution satellite orthophoto maps with a resolution better than 1.0m for the whole country.The lack of high precision control data is a critical problem in geometric positioning of high-resolution satellite images in Western China.In order to solve this problem,this paper introduces a high-resolution remote sensing satellite image geometric adjustment method and technical flow based on stereo and non-stereoscopic image co-processing.It utilizes the advantages of high resolution mapping stereo satellite images in regional network adjustment network,and solves the control resources needed for non-stereo high resolution satellite image adjustment,and realizes the geometric orientation of non-stereo high resolution satellite images under uncontrolled (sparse control) conditions.The engineering practice results show that the technical method and process are feasible,and the data processing accuracy meets the requirements of Third National Land Survey orthophoto productions.
