Paper Abstract

A direct method of motion estimation and structure reconstruction for various motion forms has been proposed based on optical flow. First, a motion estimation energy function is established by redesigning the data term and the smoothing term under the assumption of three-dimensional motion constancy. Next, the Euler-Lagrange iterative formula for motion estimation is obtained with the variational method. Finally, the relative depth and a dense structure are recovered from the estimated motion velocities. Experimental results show that the proposed method is more precise and robust for estimating and reconstructing various motion forms.
