Abstract

The problem of visual servoing to reach the desired location keeping elliptical projections in the camera field of view (FOV) while following a straight line is considered. The proposed approach is representing the whole path with seven polynomials of a path abscise: variables in polynomial coefficients for translational path being zero to represent a minimum path length and for rotational part being adjustable satisfying the FOV limit. The planned elliptical trajectories are tracked by an image-based visual servoing (IBVS) controller. The proposed strategy is verified by a simulational case with a circle and a superposed point, where a traditional IBVS controller directs the camera a detour to the ground, the proposed approach however keeps straight the camera trajectory and also the circle visible. In addition, a six degrees of freedom (6-DoF) articulated arm mounted with a pinhole camera is used to validate the proposed method by taking three Christmas balls as the target.
