报告题目:Fundamental Problems in Visual Servoing: Object Matching, Global Convergence, and Path Planning

报告人:Graziano Chesi

报告摘要:The term “visual servoing” refers to the task of moving a robot to a reference position based on the images provided by cameras observing a reference object and possibly the robot. This talk considers the typical configuration known as eye-in-hand visual servoing, where only one camera is used, mounted on the robot end-effector. Three fundamental problems are discussed. The first problem, object matching, consists of establishing which object point in one view corresponds to another object point in another view. The second problem, global convergence, consists of ensuring that the reference position is reached from any possible initial one, hence guaranteeing that the reference object remains in the field of view of the camera. The third problem, path planning, consists of ensuring that workspace constraints, joint constraints, and obstacle avoidance, are taken into account, possibly optimizing a cost. Some solutions are presented for these problems.
