Accelerometer based horizon and keystone perspective correction
Because of improper camera orientation, pictures are often affected by perspective distortions. In this paper, we show how to use the on-board camera accelerometer to correct the horizon and keystone distortions, without requiring any human intervention. The experimental results demonstrate the feasibility of the proposed approach; they also suggest that an accurate accelerometer calibration is necessary to get a satisfying distortion removal.
