Combining Cartesian and polar coordinates in IBVS
Corke, Peter, Spindler, F., & Chaumette, F. (2009) Combining Cartesian and polar coordinates in IBVS. In 2009 IEEE/RSJ International Conference on Intelligent Robots and Systems, IROS 2009.
Image-based visual servo (IBVS) is a simple, efficient and robust technique for vision-based control. Although technically a local method in practice it demonstrates almost global convergence. However IBVS performs very poorly for cases that involve large rotations about the optical axis. It is well known that re-parameterizing the problem by using polar, instead of Cartesian coordinates, of feature points overcomes this limitation. First, simulation and experimental results are presented to show the complementarity of these two parameter-izations. We then describe a new hybrid visual servo strategy based on combining polar and Cartesian image Jacobians. Â© 2009 IEEE.
