Yuquan Wang, Johan Thunberg, Xiaoming Hu
2012 2012 IEEE 51st IEEE Conference on Decision and Control (CDC)  
We assume that the pose is possible to retrieve from the observations of the point features, i.e., we have a Position Based Visual Servoing Problem with constraints.  ...  We introduce a two step method that transforms the problem into a convex optimization problem with linear constraints. In the first step the rotational motion is restricted to be of a certain type.  ...  Traditionally visual servoing has been divided into two categories: Image Based Visual Servoing (IBVS) [2] and Position Based Visual Servoing (PBVS) [2] .  ...

Particle filter-based direct visual servoing

Quentin Bateux, Eric Marchand
2016 2016 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS)  
With respect to classical visual servoing (VS) technics based on geometrical features, the main drawback of direct visual servoing is its limited convergence area.  ...  In this paper we propose a new direct visual servoing control law that relies on a particle filter to achieve non-local and non-linear optimization in order to increase this convergence area.  ...  PF-based visual servoing control law As seen in the Section II, visual servoing can be viewed as an optimization problem.  ...
