Method for recovery of heading from motion

Abstract

Based on Longuet-Higgins & Prazdny's algorithm, a new method was developed. In the algorithm, a radial virtual flow field is generated and the difference between the original velocity field and the virtual radial field is computed. The difference vectors, which are directed to the heading point in the projected plane, allow us to estimate the direction of heading. The simulations of the algorithm were performed and it was shown that the method estimates the direction of heading accurately.2
