Dynamic visual servoing of a small scale autonomous helicopter in uncalibrated environments

This paper presents a novel adaptive controller for image-based visual servoing of a small autonomous helicopter to cope with uncalibrated camera parameters and unknown 3D geometry of the feature points.The controller is based on the back-stepping technique,but its design has two new features.First,it incorporates the visual feedback into the last step of the backstepping procedure,while existing backstepping-based methods employ the visual feedback at the early steps.Second,the controller maps the image er...
