Finding the Optimal Pose of 2D LLT Sensors to Improve Object Pose Estimation

open access: yesSensors, 2022
In this paper, we examine a method for improving pose estimation by correctly positioning the sensors relative to the scanned object. Three objects made of different materials and using different manufacturing technologies were selected for the ...

2-D distributed pose estimation of multi-agent systems using bearing measurements

open access: yesJournal of Automation and Intelligence, 2023
This article studies distributed pose (orientation and position) estimation of leader–follower multi-agent systems over κ-layer graphs in 2-D plane. Only the leaders have access to their orientations and positions, while the followers can measure the ...

Estimating Orientation of Flying Fruit Flies

open access: yesPLOS ONE, 2015
The recently growing interest in studying flight behaviours of fruit flies, Drosophila melanogaster, has highlighted the need for developing tools that acquire quantitative motion data. Despite recent advance of video tracking systems, acquiring a flying fly's orientation remains a challenge for these tools. In this paper, we present a novel method for

A Fast and Simple Method for Absolute Orientation Estimation Using a Single Vanishing Point

open access: yesApplied Sciences, 2022
Absolute orientation estimation is one of the key steps in computer vision, and n 2D–3D point correspondences can be used to obtain the absolute orientation, which is known as the perspective-n-point problem (PnP).

Extension of the Rigid-Constraint Method for the Heuristic Suboptimal Parameter Tuning to Ten Sensor Fusion Algorithms Using Inertial and Magnetic Sensing

open access: yesSensors, 2021
The orientation of a magneto-inertial measurement unit can be estimated using a sensor fusion algorithm (SFA). However, orientation accuracy is greatly affected by the choice of the SFA parameter values which represents one of the most critical steps.

Influence of skull conductivity perturbations on EEG dipole source analysis [PDF]

open access: yes, 2010
PURPOSE: Electroencephalogram (EEG) source analysis is a noninvasive technique used in the presurgical of epilepsy. In this study, the dipole location and orientation errors due to skull conductivity perturbations were investigated in two groups of three-

Global orientation estimation in noisy conditions

open access: yesActa Neurobiologiae Experimentalis, 2015
The present paper studies the perceived orientation of line patterns with variable elongation, line length, orientation jitter, and presentation time. It evaluates whether the internal noise and sampling efficiency evaluated by equivalent noise paradigm (Pelli 1981) depend on the spatial configuration and temporal characteristics of the stimulation ...
