Problems solved by technology

In order to determine the relative position relationship between the angle sensor component and the gimbal at the factory, mechanical calibration is required, and the mechanical calibration generally requires the use of fixtures at this stage. Put the gimbal into the calibration jig to keep the gimbal at the mechanical zero position, and connect the gimbal Calibrate through the calibration software after powering on. This method will bring additional operations and tool requirements due to the need for fixtures, which is extremely inconvenient.
[0004] The IMU components composed of MEMS sensors are widely used

Abstract

The invention discloses a holder calibration method. The method comprises the steps that a holder driving motor is rotated to a motor limit gear or a position where a marked graduation line of the motor is located or a position when a mobile phone is horizontal after a holder is electrified; a user operation host computer sends a calibration instruction, and a holder MCU receives the calibration instruction, enters a calibration state and records a corresponding position attitude A of the motor; and the holder is disconnected from the host computer and restarted to enter a normal work mode, an IMU assembly measures a real-time attitude angel B, and the MCU obtains the real attitude angle of the holder by calculating B-A. The holder calibration method is characterized by simple operation, high calibration efficiency and high reliability.

Description

technical field [0001] The invention relates to the field of cloud platforms, in particular to a method for calibrating a cloud platform. Background technique [0002] The gimbal is a load-bearing device for installing and fixing cameras or mobile phones and other shooting devices. It can monitor external disturbances according to the attitude sensing component, drive the motor to rotate the connected structural components, and keep the camera or mobile phone at a stable level, thereby ensuring the quality of the shooting picture. [0003] The gimbal attitude sensing component is generally composed of an angle sensor component and an inertial measurement unit (IMU). They are fixedly connected to the motor and can monitor the motion status of the camera or mobile phone in real time, especially the horizontal attitude angle. In order to determine the relative position relationship between the angle sensor component and the gimbal at the factory, mechanical calibration is requi...
