Abstract

In this paper, we apply Wide-Field integration (WFI) of optic flow for the state estimation of a planetary landing vehicle. This study utilizes nonlinear expressions for the Fourier coefficients of the optic flow instead of linearized expressions. By using the nonlinear expressions, it is shown that the vehicle's attitude angles can be estimated as well as its velocity components. First this paper deals with a two-dimensional model and explains how to estimate state variables. Then two three-dimensional models are discussed. Numerical simulation results are shown to evaluate the estimation accuracy.
