摘要: 近年来国产卫星传感器类型日益丰富,使用自主可控的国产卫星影像进行生产和研究的需求越来越大,多源国产卫星影像联合平差的精度分析显得尤为重要。本文针对在立体测图生产中,资源三号卫星影像在时相较旧、噪声较大、云覆盖和摄影漏洞等特殊困难的条件下,利用天绘一号卫星影像进行补漏生产的情况,最终分析并验证了两者无控联合平差的可行性和成果精度。

Abstract: In recent years, more and more types of domestic satellite sensors are available. There is a growing demand for production and research using autonomous and controllable domestic satellite images. The accuracy analysis of combined adjustment of multi-source domestic satellite images is important particularly. This paper introduces the situation of combined mapping production by using ZY-3 and TH-1 in the special difficult conditions,such as outdated situation, high noise, cloud coverage area and photographic gap. And the feasibility and accuracy of combined block adjustment without control with GCP for ZY-3 and TH-1 are verified.

Key words: ZY-3, TH-1, combined block adjustment, accuracy analysis, stereo mapping
