For the depth estimation problem in the image-based visual servoing (IBVS) control, this
paper proposes a new observer structure based on Kalman filter (KF) to recover the feature …

This article proposes a new approach to achieve direct visual servoing (DVS) based on
discrete orthogonal moments (DOMs). DVS is performed in such a way that the extraction of …

Abstract The SE (3) SE (3) invariants of a pose include its rotation angle and screw
translation. In this paper, we present a complete comprehensive study of the relative pose …

In this paper, an autonomous landing guidance strategy is proposed for quad-UAVs,
including landing marker detection, altitude estimation, and adaptive landing commands …

As a visual measurement method, photogrammetry is widely used in engineering
measurement fields. Photogrammetry must first complete camera pose estimation. However …

Image moments are global descriptors of an image and can be used to achieve control-
decoupling properties in visual servoing. However, only a few methods completely decouple …
