摘要：STARIMAGER is a helicopter-mounted high resolution Three-Line Scanner (TLS) imaging system developed by STARLABO Corporation jointly with the University of Tokyo for large scale mapping, temporary linear ground objects investigation, and remote sensing applications in 2000. As other airborne and spaceborne linear imaging sensors, STARIMAGER is equipped with GPS/IMU to record the exterior orientation parameters of each obtained image line during flight. However, the recorded GPS/IMU data couldn't be used until their some systematic errors such as offsets between GPS antenna and perspective centre, misalignment between IMU axes and camera coordinate system axes, and drifts of IMU with time elapse etc. with similar conventional aerial triangulation. Moreover, to achieve high pointing accuracy with STARIMAGER imagery and minimum ground control points, we tested several orientation strategies including different sensor models, different block configuration and control information with the real flight data and obtained excitement results in this paper. We sure these experimental orientation strategies will be valuable for other future applications with airborne and spaceborne linear imagery
