The invention relates to the technical field of unmanned aerial vehicles, and provides an unmanned aerial vehicle undercarriage which is characterized in that the height from an unmanned aerial vehicle to the ground is obtained through a ground height ranging module, and when it is detected that the height from the ground is a set height value, the unmanned aerial vehicle hovers; then the ground is scanned through a three-dimensional laser scanner, three-dimensional point cloud data of the ground are obtained, and landing terrain data are obtained; the data processing module analyzes the landing terrain data to determine the telescopic adjusting amount of each landing telescopic supporting leg, so that the length of each landing telescopic supporting leg is adjusted; and finally, when the unmanned aerial vehicle lands on the ground, the inclination angle data of the unmanned aerial vehicle are collected through a mounting base plane inclination angle measurement module, and the lengths of the landing telescopic supporting legs are secondarily adjusted according to the inclination angle data of the unmanned aerial vehicle. Thus, the lengths of the landing telescopic supporting legs can be adaptively adjusted according to the landing terrain, the risk that the unmanned aerial vehicle tilts laterally is avoided, and stable landing of the unmanned aerial vehicle is guaranteed.

    本发明涉及无人机技术领域,提供了一种无人机起落架,本发明通过地面高度测距模块得到无人机距离地面高度,当检测到距离地面高度为设定高度值时,使得无人机进行悬停;然后通过三维激光扫描仪对地面进行扫描,获取地面的三维点云数据,得到降落地形数据;接着数据处理模块对降落地形数据进行分析确定各个起落伸缩支腿的伸缩调节量,使得起落伸缩支腿的长度进行调节;最后当无人机降落至地面,通过安装基座平面倾斜角测量模块采集无人机倾斜角数据,根据无人机倾斜角数据使得起落伸缩支腿的长度进行二次调节。如此,起落伸缩支腿的长度能够根据降落地形进行自适应调节,避免了无人机发生侧倾的风险,保证了的无人机平稳降落。
