Vision-Aided Relative State Estimation for Approach and Landing on a Moving Platform with Inertial Measurements
Tarek Bouazza, Alessandro Melis, Soulaimane Berkane +2
This paper tackles the problem of estimating the relative position, orientation, and velocity between a UAV and a planar platform undergoing arbitrary 3D motion during approach and…
Scalar-Measurement Attitude Estimation on with Bias Compensation
Alessandro Melis, Tarek Bouazza, Hassan Alnahhal +3
Attitude estimation methods typically rely on full vector measurements from inertial sensors such as accelerometers and magnetometers. This paper shows that reliable estimation can…
Relative Pose-Velocity Estimation Using Dual IMU Measurements and Relative Position Sensing
Alessandro Melis, Tarek Bouazza, Soulaimane Berkane +1
This paper addresses the problem of estimating the relative pose (position and orientation) and velocity of a vehicle with respect to a moving target, where both are equipped with…
Equivariant Observer Design on SL(3) for Image Intensity-Based Homography Estimation
Tarek Bouazza, Pieter van Goor, Robert Mahony +1
This paper addresses the problem of homography estimation using a nonlinear observer designed on the Lie group that exploits the full image information through dir…
Observer Design for Optical Flow-Based Visual-Inertial Odometry with Almost-Global Convergence
Tarek Bouazza, Soulaimane Berkane, Minh-Duc Hua +1
This paper presents a novel cascaded observer architecture that combines optical flow and IMU measurements to perform continuous monocular visual-inertial odometry (VIO). The propo…
A Simple Algebraic Solution for Estimating the Pose of a Camera from Planar Point Features
Tarek Bouazza, Tarek Hamel, Claude Samson
This paper presents a simple algebraic method to estimate the pose of a camera relative to a planar target from reference points with known coordinates in the target fra…
