Full spectrum vibration suppression for video stabilization

Stable and clear video imaging system is crucial in various industry applications for monitoring and remote control purposes. Severe vibrations across full spectrum frequencies are inevitable in many industrial operations resulting in shaky and unclear images. It may reduce the response time for operator and also affect the throughput during the production or monitoring process. On the other hand, commercially available cameras with built-in image stabilization functions may not be sufficient to overcome this problem since they only deal with camera shaking at small magnitude. To stabilize images captured under sever and full spectrum vibration condition, a vibration suppression system was developed. The system consists of a passive vibration mechanism and a digital image stabilization technique. The eddy current damper inside the passive vibration mechanism reduces high frequency vibration, while the digital image stabilization shifts the image for low frequency vibration elimination. Trial results have demonstrated the effectiveness of the system's capability to cover full vibration spectrum. However, it is also found that it needs to increase the degree-of-freedom (DOF) for this mechanism in the future instead of only single DOF.
