摘要
机载三维成像仪是集成GPS、姿态测量装置、激光测距仪和光谱成像仪的新型航空遥感系统,它能同步获取地面目标的定位、定性数据。本文简要介绍了机载三维成像仪系统,在计算出扫描激光测距点三维坐标的基础上,着重分析了DTM快速生成算法,包括DTM的快速内插和航带间的自动无缝拼接。
Airbome 3D imager that integrates GPS,attitude measurement unit,scanning laser rangefind-er and scanner is a new remote sensing technology system.It can produce digital surface model(DTM)without ground control points.In this paper we focus on the algorithm to produce DTM image.The al-gorithm includes DTM interpolation and strips mosaic.According to the test result,the algorithm is fea-sible.
