The invention discloses a coaxial dual-rotor unmanned aerial vehicle, and belongs to the technical field of unmanned aerial vehicles. A vertical cylindrical fuselage and coaxial double propellers are adopted to provide power, and the aircraft is controlled by changing the pulling force direction and the rotating speed difference of the double rotors. According to the invention, a GNSS positioning device and a visual positioning device can also be adopted to be fused with an IMU to form an inertial satellite integrated navigation and visual-inertial navigation synchronous positioning and mapping VI-SLAM navigation and positioning system, and autonomous flight can be realized no matter in an open environment covered by a GNSS or in a closed and GNSS denial environment. The aircraft has the attributes of generalization, informatization, autonomy, intelligence and the like, is simple in structure, low in cost, high in cost-effectiveness ratio, firm, durable and convenient to carry, can provide global situation information of parts, such as streets, indoor places, jungles and the like, which cannot enter, cannot be reached and cannot be seen, and can complete detection or search and rescue tasks of closed and shielded spaces, such as cities, jungles, indoor places and the like.
本发明公开了一种共轴双旋翼无人飞行器,属于无人机技术领域。采用竖直圆柱形机身,共轴双桨提供动力,通过改变拉力方向及双旋翼转速差实现飞行器的控制。本发明还可以采用GNSS定位设备与视觉定位设备,分别与IMU融合组成惯性卫星组合导航以及视觉‑惯导同步定位与建图VI‑SLAM导航定位系统,无论在有GNSS覆盖的空旷环境,还是在密闭和GNSS拒止的环境,均可实现自主飞行。飞行器具备通用化、信息化、自主化、智能化等属性,并且结构简单、成本低、效费比高、坚固耐用、携带方便,可提供街道、室内、丛林等“进不去、够不着、看不见”部位的全局态势信息,完成城市、丛林、室内等密闭与遮挡空间探测或搜救任务。
