本发明实施例涉及一种风速测算方法及无人机。该风速测算方法包括:获取所述无人机的飞行数据信息,其中,所述飞行数据信息包括所述无人机当前的姿态角、速度以及加速度;利用所述飞行数据信息,建立所述无人机的速度观测模型,以获得所述无人机的速度观测值;根据所述速度观测值,获取所述无人机所受的风力的观测值;根据所述风力的观测值,计算当前飞行环境下的风速。该方法在不依赖新增风速传感器和外部数据库的前提下,实现了风速测算,既节省了硬件设备的成本,又不会带来额外的算力负担和实时性的问题,方法简单并且成本低廉。而且,基于风力测算的运算结果,可以将其应用于预警功能,对使用者进行提示,减少无人机事故发生的概率。

    The embodiment of the invention relates to a wind speed calculation method and an unmanned aerial vehicle. The wind speed calculation method comprises the following steps: acquiring flight data information of the unmanned aerial vehicle, wherein the flight data information comprises the current attitude angle, speed and acceleration of the unmanned aerial vehicle; establishing a speed observation model of the unmanned aerial vehicle by utilizing the flight data information, thereby acquiring a speed observation value of the unmanned aerial vehicle; acquiring the observation value of the wind power borne by the unmanned aerial vehicle according to the speed observation value; and computing the wind speed under the current flight environment according to the observation value of the wind power. Through the method disclosed by the embodiment of the invention, the wind speed calculation is realized in the premise of being independent of a newly added wind speed sensor and an external database, the cost of the hardware equipment is saved, and the problem of additional computing burden and instantaneity cannot be caused, the method is simple and low in cost; and meanwhile, an operation result based on the wind power calculation can be applied to an early-warning function, thereby prompting the user, and reducing the occurrence probability of the unmanned aerial vehicle accident.
