System and method for video stabilization of rolling shutter cameras

摘要

Example embodiments presented herein are directed towards rolling shutter video stabilization utilizing three dimensional motion analysis. In stabilizing the rolling shutter video, a three dimensional motion of the device capturing the image may be determined or estimated. In some example embodiments the three dimensional motion may be a purely rotational motion, a purely translation motion, or a rotational and translational motion. The estimated three dimensional motion may be utilized to adjust the pixels of an image frame in order to rectify and stabilize the video image.

1. A method for video stabilization of a video image from a rolling shutter camera, the method comprising the steps of:
interpolating a three dimensional row motion of the rolling shutter camera for each image row from a matrix calculation with an estimated and/or obtained three dimensional frame motion at frame references, said estimated and/or obtained three dimensional frame motion representing a three dimensional motion of the rolling shutter camera; and stabilizing the video image by adjusting pixels to compensate for the three dimensional row motion obtained in the interpolating step.
