Abstract

The invention discloses a pan-tilt calibration method and a calibration system. The method comprises: placing the pan-tilt to be calibrated on a horizontal calibration platform, and forming a communication connection with a relay module of the calibration platform; Follow the calibration instructions forwarded by the module, and perform pan-tilt calibration according to the received calibration instructions when the pan-tilt is still. In the present invention, the pan-tilt to be calibrated is placed on a horizontally set calibration platform, and forms a communication connection with the relay module of the calibration platform to receive the calibration instruction forwarded by the relay module to perform automatic calibration, without special fixtures, reducing The production cost is low, and the calibration operation is simple.

Description

technical field [0001] The present invention relates to the technical field of machine / instrument calibration, in particular to a pan / tilt calibration method and a calibration system. Background technique [0002] The sensors used in the gimbal include an IMU (inertial measurement unit) and a magnetically encoded sensor (or Hall sensor). The IMU consists of a gyroscope and an accelerometer. The gyroscope measures the angular velocity of the xyz axis, and the accelerometer measures the angle value of the joint angle of the xyz axis. Generally, the control of the pan / tilt from the outer loop to the inner loop is position loop-velocity loop-current loop. Among them, the position loop needs accurate gyroscope and accelerometer values ​​for attitude calculation, and the velocity loop needs accurate joint angle values ​​for velocity decoupling. , the speed loop also needs accurate gyroscope values, and the current loop needs accurate electrical angle values. Therefore, the calib...
