Stereo Measurement on Imagestation with Starimager - Airborne Three-line Scanner - Imagery

STARIMAGER is a helicopter-borne high resolution digital Three-Line Scanner (TLS) imaging system developed by STARLABO Corporation jointly with the University of Tokyo and ETH-Hoenggerberg for large scale mapping, linear-shaped ground objects investigation (such as roads, rivers, railways, pipelines, etc.), and remote sensing applications. As with other airborne and spaceborne linear imaging sensors, STARIMAGER is equipped with GPS/IMU to record the exterior orientation parameters of each obtained image line per forward, nadir and backward views during a flight. This paper describes the integration and ingestion of the TLS images that have been rectified and triangulated by STARLABO Corporation into Z/I Imaging Corporation’s 3-D feature and DTM collection and orthophoto production products. The paper also presents some field results of the 3-D feature collection and accuracy evaluation with real TLS flight data.
