An empirical comparison of methods for image-base motion estimation
Conference Paper, Proceedings of (IROS) IEEE/RSJ International Conference on Intelligent Robots and Systems, Vol. 1, pp. 123 - 128, September, 2002
Abstract
This paper presents a comparison between methods that estimate motion of a camera from a sequence of video images. We have implemented two methods?a homography based method that assumes planar environments, and shape-from-motion, a general method that can deal with a fully three dimensional world. Both methods have been formulated in an iterative, online form to produce estimates of camera motion. We discuss a trade-off in accuracy and run time efficiency based on experimental results for these two general methods in relation to ground truth. We show how a variation of the homography method can produce accurate results in some cases when the environment is non-planar, with low computational cost.
