ALTITUDE DETECTION METHOD, METHOD AND DEVICE FOR DETERMINING COMPENSATION, AND UNMANNED AERIAL VEHICLE

Title:

ALTITUDE DETECTION METHOD, METHOD AND DEVICE FOR DETERMINING COMPENSATION, AND UNMANNED AERIAL VEHICLE

Document Type and Number:

WIPO Patent Application WO/2021/217329

Kind Code:

A1

Abstract:

An altitude detection method, comprising: acquiring posture information of an unmanned aerial vehicle and acquiring a current detected altitude corresponding to the posture information (S101); determining an altitude drop compensation corresponding to the posture information (S102); and utilizing the altitude drop compensation to compensate the current detected altitude to acquire a target altitude corresponding to the posture information (S103). By acquiring the current detected altitude corresponding to the posture information and the altitude drop compensation corresponding to the posture information, and by utilizing the altitude drop compensation to compensate the current detected altitude, the incorporation of the posture information of the unmanned aerial vehicle in the estimation of the altitude drop compensation corresponding to the posture information is effectively implemented, and altitude measurement errors of a barometer caused by movements and outside wind and airflow while the unmanned aerial vehicle is in flight are compensated, thus ensuring the acquisition of precise and accurate altitude information, and ensuring the stability and reliability of using the method. Also disclosed are an altitude detection device, a method for determining a compensation, a device for determining a compensation, and the unmanned aerial vehicle.
