A pose-free 2D-3D hybrid approach for visual servoing control systems

This work is set to design pose-free visual feedback control laws. Our contribution is linked to improving 3D pose-free visual servoing strategy using 2D predictions of visual features’ trajectories. Given a set rigid body characterized by a set of 3D point features, our proposed visual servoing strategy enhanced with predictive elements is based on computing the following sample time positions of the point features given the known camera velocity from the previous time moment. In this way, the architecture decides to discard the point feature before exiting the field of view. Thus, any unnecessary computations are removed, and the camera’s motion is ensured to be more natural. The simulation results emphasize the potential of the new visual control architecture.
