摘　　要：ADS40是当今最先进的摄影测量系统之一,它采用推扫式三线阵获取影像,可以提供多种类型的数字影像数据。由于配备IMU/DGPS系统,在一定的基站范围内可以在无控制或少量控制点的情况下进行空三平差,极大地减轻了摄影测量外业控制工作量,缩短了生产周期,提高了作业效率。本文就ADS40的原理、数据处理流程,以及ADS40和常规摄影测量的区别,在精度等方面作了阐述和分析,并就其在我国摄影测量领域内的应用进行了展望。ADS40 is one of the advanced photogrammetry system today.It uses three-line-scanner in image acquisition with pushbroom mode,and can provide many kinds of digital images.With IMU/DGPS system,it can process bundle adjustment successfully with less GCPs or even without GCPs with a GPS base station located in a certain scope.So it will remarkably reduce the workload of field,and improve producing efficiency and save time.The principle,workflow of data processing,the difference between ADS40 and the traditional photogrammetry and the precision of ADS40 are presented in the paper.The development and application of the technology in the field of photogrammetry in western China are also briefly described.
