A Method of Resolving Gyro Zero Drift in Electronic Stabilization System

For the gyroscope´s zero-drift problem in electronic image stabilization system, this paper proposes a solution - the principle of the cumulative time demarcation. First of all, let gyroscope collect two minutes data, and then process the data after denoising it and obtain the gyro´s zero. Regard it as the initial standard, and then conduct a zero calibration every 30 minutes. The data collected in this way will reduce accumulative errors brought about by the zero drift. The experiment done in lab of the electronic image stabilization system shows: This method can effectively solve the problem that the video image goes out the screen caused by the gyroscope´ zero drift.
