Problems solved by technology

Among them, for the airborne gimbal, the error in the heading can be compensated by the magnetic compass on the flight controller of the UAV, but in the case of strong magnetic field interference, the magnetic compass is greatly affected by the interference, so it cannot It is suitable for compensating heading errors, and for specific applications such as handheld stabilized platforms, there is no magnetic compass on the device itself, and it is impossible to compensate heading errors through a magnetic compass

Abstract

The embodiment of the invention provides a compensation method and device for holder drift, a holder and an unmanned aerial vehicle, and is applied to the technical field of the unmanned aerial vehicle. The compensation method comprises the following steps: through a first image and a second image collected by an image acquisition device on the holder, obtaining a holder drift angle, and controlling the holder to move to compensate the drift angle. According to the compensation method, the technical problem that the estimation and the compensation of the holder drift cannot be accurately carried out when the zero drift of a gyroscope is compensated is solved.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a compensation method and device for pan-tilt drift, a pan-tilt and an unmanned aerial vehicle. Background technique [0002] In related technologies, the stabilized platform device of the UAV reads the gyroscope data, calculates and obtains the motion angle of the gyroscope sensitive platform relative to the inertial coordinate system, and compensates the angle by the closed-loop control torque motor to overcome the influence of the carrier motion , to ensure that the sensitive platform of the gyroscope remains at the local level. However, the gyroscope in the gyroscope or the inertial measurement unit (IMU for short) has a zero point drift, and there will be a large error in long-term cumulative calculation. In order to compensate the error caused by the drift of the gimbal, other sensors can be used to obtain information to estimate and compensate the drift o...
