Typically, airborne laserscanning includes a laser mounted on an airplane or drone (its pulsed beam direction can scan in flight direction and perpendicular to it) an intertial positioning system of gyroscopes, and a global navigation satellite system. The data, relative orientation and relative distance of these three systems are combined in computing strips of ground surface point locations in an earth fixed coordinate system. Finally, all laserscanning strips are combined via iterative closest point methods to an interactive three-dimensional terrain map. In this work we describe the mathematical framework for how to use the iterative closest point method for the adjustment of the airborne laserscanning data strips in the framework of conformal geometric algebra.

通常，机载激光扫描包括安装在飞机或无人机上的激光器（其脉冲光束方向可以在飞行方向上扫描并与其垂直），陀螺仪的惯性定位系统，以及全球导航卫星系统。将这三个系统的数据、相对方位和相对距离组合成地球固定坐标系中地表点位置的计算条。最后，所有激光扫描条通过迭代最近点方法组合成交互式三维地形图。在这项工作中，我们描述了如何在共形几何代数的框架下使用迭代最近点方法调整机载激光扫描数据条的数学框架。
