Title:
CONTROL METHOD AND SYSTEM FOR CRADLE HEAD, CRADLE HEAD, AND UNMANNED AERIAL VEHICLE
Document Type and Number:
WIPO Patent Application WO/2018/120059
Kind Code:
A1
Abstract:
A cradle head (1) comprises: a mounting portion for mounting a load; a magnetic sensor (30); an inertial sensor (40); and a controller (20). The controller (20) is configured to: use the magnetic sensor (30) to determine a first deflection angle through which the mounting portion rotates around a yaw axis within a time period, use the inertial sensor (40) to determine a second deflection angle through which the mounting portion rotates around the yaw axis within the time period, determine, according to the first deflection angle and the second deflection angle, an angle error of the inertial sensor (40), and use measurement data of the inertial sensor (40) having undergone angle error correction to control an orientation of the cradle head (1).
