Video stabilization technique based on optical flow sensor
In allusion of the video jitter problem caused by platform motion, a video stabilization technique based on optical flow sensor is presented. Firstly, the scheme improves the general optical flow sensor to output accurate motion vectors under rotational motion, then motion vectors between adjacent frames are obtained by using the optical flow sensor. The real-time translation and rotation information of the main camera are calculated through coordinate transformation. Secondly, the method compensates the motion of video sequences to attain stable video sequences, and finally realizes video stabilization. Experimental results indicate that, compared with the unstable image, the peak signal-to-noise ratio (PSNR) is increased by 11.86 dB. In the case of obvious video jitter, the scheme can significantly reduce the jitter between video sequences. The method which has the characteristics of salutary video stabilization can meet the performance requirements of video stabilization and improve the capacity of disturbance resistance for platform.
