Shipborne Camera Video Stabilization Base on Horizon

Abstract

In this paper a new horizon-based shipborne camera video stabilization algorithm is implemented. First, the edges are obtained by Canny operator, then effective lines are obtained by Hough transform. In order to get the horizon within the existing lines, a fast filter-based method detecting the lines location differences is proposed, and image stabilization is implemented by the difference with the current horizon and base horizon. Experiments show that the algorithm can meet the real-time requirements, and can achieve the better image stabilization effect even in the conditions of bad light and fogs.

A Horizon Line Annotation Software for Streamlining Autonomous Sea Navigation Experiments

“…First, numerous papers and patents used the horizon line to auto-calibrate the camera [4][5][6], which include non-maritime scenes as well [7,8]. Second, the position and tilt of the horizon allows the computation of rotation and translation matrices that would digitally stabilize captured video frames [9][10][11][12][13][14][15][16][17]. A stabilized video is not only easier to watch but facilitates subsequent analyses as well [2,11,17].…”
