利用3维成像仪快速生成遥感地学编码图像

机载３维成像仪是集成了ＧＰＳ、姿态测量装置、扫描激光测距仪和扫描光谱成像仪的 一代航空遥感系统，它能利用飞行所获取的原始数据直接生成数字正射影像图，而无需任何地面控制点，本文首先简要介绍了机载３维成像仪系统的基本原理，然后在计算出扫描激光要样点３维坐标的基础上，着重分析了快速生成遥感地学编码影像的算法，包括利用激光测路点坐标精确纠正原始图像，图像的灰度快速内插和各航带间的全自动无终拼接等算法，经过试验研究，该方法切实可行，可以满足种种上实时，准实时的遥感应用要求。

Fast Generating Geo-referenced Image Based on Airborne 3D Imager

Airborne 3D imager, which integrates Global Positioning System (GPS), Inertial Navigating System (INS), scanning laser rangefinder and scanner, is a new airborne remote sensing technology system which can generate geo referenced image and Digital Elevation Model(DEM) without any Ground Control Points(GCPs). The principle of airborne 3D imager is first introduced in this paper, and then the procedure of calculating the position of laser sample point is briefly given. How to fast generate the geo referenced image is presented in detail, such as rectifying the raw image, interpolating gray level, mosaicking strips automatically. According to the test, the processing method is feasible to the 3D imager and can meet the requirement of real time applications.
