Symp. on Robotics, ISR'04 %C Paris, France %X This paper presents new advances in the field of visual servoing. More precisely, we consider the case where complex objects are observed by a camera. In a first part, planar objects of unknown shape are considered using image moments as input of the image-based control law. In the second part, a pose estimation and tracking algorithm is described to deal with real objects whose 3D model is known. For each case, experimental results obtained with an eye-in-hand system are presented %U http://rainbow-doc.irisa.fr/pdf/2004_isr_comport.pdf %8 March %D 2004
