摘　　要：A3数字航摄仪是由以色列VisionMap公司生产的新一代步进式分幅成像数字航摄仪,A3为300 mm长焦相机,两个镜头平行于飞行方向并排安置,采用摆扫成像的方式获取影像数据。由于A3航摄仪在军事侦察领域性能优异,在VisionMap公司被以色列国防部收购之后,A3航摄仪被禁止出口至我国。国内西安光学精密机械研究所等机构已经开展面阵摆扫传感器的研发和制造,但国内关于面阵摆扫式航空影像数据的处理方法仍相当匮乏。在此背景下,本文以A3航摄仪为研究对象展开对面阵摆扫式航空影像处理方法的研究,主要介绍A3航摄仪的系统构成及其性能、优势,并探讨其摄影测量处理过程,最后对其主要应用前景进行展望。A3 is VisionMap’s all-in-one large-format mapping and oblique digital camera system.The camera’s dual 300 mm focal length telescopes are set abreast and parallel to the direction of flight.Because of the excellent performance of A3 aerial camera in military reconnaissance.A3 has been forbidden to export to China after the company has been purchased by Israeli Ministry of Defense.Although Xi’an Institute of Optics Precision Mechanics and other institutions have carried out the research and manufacturing of sweeping matrix array sensors.The methods for processing aerial image of matrix array sweeping sensor are still quite lacking.In this background,this paper focuses on the A3 aerial camera as a research object,to develop a processing method for matrix array sweeping aerial images.The system composition,performance and the advantages of A3 are mainly introduced in the paper.And then the processing process is discussed.Finally,this paper makes a prospect about the future application prospects of A3.
