A kind of PTZ stabilization system in ocean buoy based on the gyroscope and electronic compass module

摘要

For the swing problem of ocean buoy under billowy environment, which is hard to obtain clear and stable image, this paper designed a kind of PTZ stabilization system platform based on gyroscope and electronic compass module. During the angle data collection process, we adapt accelerometer trigonometric function method to overcome not only the low accuracy problem with a single sensor, but also accumulative error to a large extent. With the vertical direction gyroscope, the experiment results show that the angle errors of proposed accelerometer trigonometric function method are within ±1 degree which has a better practicality.
