摘要

针对大范围、高精度数字高程模型（Digital Elevation Model，DEM）数据难以获取的问题，本文提出了一种利用天绘一号卫星影像制作大范围高精度DEM的方法。提出基于少量地面控制点的RPC（Rational Polynomial Coefficients）模型精化算法，进一步提高了天绘一号卫星影像定位精度；提出特征与整体松弛相结合的匹配方法，实现了立体影像高精度匹配；利用精化后的天绘一号卫星影像RPC模型以及立体匹配得到的同名点数据，进行前方交会得到高精度的DEM数据。本文利用东北辽西某地区的影像数据进行了实验，实验结果表明：利用单景天绘一号卫星影像生成的DEM数据，覆盖范围达到60 km×60 km；在无地面控制点条件下，生成的DEM数据高程精度可达5.12 m，满足1：50 000地形图成图精度要求；在3个地面控制点条件下，生成的DEM数据高程精度3.01 m，满足1：25 000地形图成图精度要求。

Abstract

Aimed at the issue that difficultly obtaining digital elevation model (DEM) with large scale and high precision

a method utilizing TH-01 Mapping Satellite image to make DEM with large scale and high precision was discussed in the thesis. RPC model refined algorithm based on a few ground control points was proposed

and positioning accuracy of TH-01 Mapping Satellite image was improved further; matching method combined with feature and overall relaxation was proposed

and high-precision matching for stereo image was realized; PRC model for TH-01 Mapping Satellite image after refinement and homonymy point data obtained by stereo matching were utilized to conduct forward intersection to obtain high-precision DEM data. Image data in some place in western Liaoning of northeast was provided with experiment in the thesis

and experiment result shows that coverage scope of DEM data generated by taking advantage of mono TH-01 Mapping Satellite image reaches 60 km×60 km; under the condition that there is no ground control point

elevation precision of generated DEM data is 5.12 m

meeting precision requirements of the topographic map on a scale of 1:50 000; under the condition that there are 3 ground control points

elevation precision for generated DEM data is 3.01 m

meeting precision requirements of the topographic map on a scale of 1:25 000.
