The invention relates to the field of unmanned aerial vehicle surveying and mapping, and provides a surveying and mapping method for automatically scanning a road by an airborne three-dimensional laser scanner in order to solve the problem of crash caused by collision when an unmanned aerial vehicle performs automatic return flight in existing unmanned aerial vehicle surveying and mapping, and the surveying and mapping method comprises the following steps: a flight step: the unmanned aerial vehicle flies according to a preset flight route; a scanning step: a scanner carried by the unmanned aerial vehicle scans the scenery in the flight route and obtains the three-dimensional coordinates of the surface of a measured object, and the obtained three-dimensional coordinates are processed to obtain a surveying and mapping image; the method further comprises the protection step that when the unmanned aerial vehicle is collided, a triggering piece of a protection system on the unmanned aerial vehicle collides with a collision object, the triggering piece triggers a buffering mechanism of the protection system to be started, and the buffering mechanism sprays air in the flight direction of the unmanned aerial vehicle and marks the collision object.

    本发明涉及无人机测绘领域,为了解决现有的无人机测绘中,在无人机进行自动返航时因为碰撞而出现坠毁的问题,提供了一种机载三维激光扫描仪自动扫描道路的测绘方法,包括以下步骤:飞行步骤:无人机根据预设的飞行航线进行飞行;扫描步骤:无人机搭载的扫描仪对飞行航线内的景物进行扫描并获得被测物体表面的三维坐标,并对得到的三维坐标进行处理得到测绘图像;其中:还包括防护步骤:在无人机发生撞击时,无人机上防护系统的触发件先与撞击物碰撞,触发件触发防护系统的缓冲机构启动,缓冲机构朝向无人机飞行方向喷气,并标记撞击物。
