一种IMU标定旋转台
By designing a symmetrical IMU calibration rotary table, the calibration process is simplified by using a motor to drive the rotary disk to rotate the IMU and the counterweight synchronously. This solves the problems of complex structure and high cost of existing devices and achieves high-precision IMU calibration.

AI Technical Summary
Technical Problem
Existing IMU calibration devices are complex in structure, have high operating costs, and low calibration accuracy.
Method used
An IMU calibration rotary table was designed, which adopts a completely symmetrical closed structure. The IMU and counterweight are rotated synchronously by a motor-driven rotary disk. Calibration is performed by comparing the motor preset signal and the IMU measurement data, which simplifies the calibration process.
Benefits of technology
It achieves low-cost, high-precision IMU calibration, has a simple structure, is easy to operate, and is suitable for IMU calibration of different measurement ranges.
