3D pose and velocity visual tracking based on sequential region of interest acquisition

— This paper presents a high speed visual tracking method based on non simultaneous subimages acquisition. This method is formulated as a virtual visual servoing scheme. The sequential acquisition of regions of interest has a double benefit on visual servoing. The first one is that this acquisition method allows to increase the visual control sampling frequency by reducing the data amount to acquire and to transmit by the camera. The second one is that the associated image projection model depends on the observed object pose and velocity. Thanks to this property, a new vision-based control law can be defined. The particularity of this control law is that the control output consists of the kinematic and the dynamic twists. This allows to enhance the control performance in trajectory tracking applications. The experimental results in high speed visual tracking application show the effectiveness of this approach.
