Micromagnetometer Calibration for Accurate Orientation Estimation [PDF]

open access: yesIEEE Transactions on Biomedical Engineering, 2015
Micromagnetometers, together with inertial sensors, are widely used for attitude estimation for a wide variety of applications. However, appropriate sensor calibration, which is essential to the accuracy of attitude reconstruction, must be performed in advance.

Nonparametric Calibration for Age Estimation

open access: yesJournal of the Royal Statistical Society Series C: Applied Statistics, 2002
SUMMARY A method is proposed for the calibration of a continuous random variable when the dependent variables are a combination of continuous and categorical, and the model between the controlling variables and calibrated variable is empirically derived.

Calibration Ratio Estimators of Population Mean Using Median of Auxiliary Variable [PDF]

open access: yes, 2022
In this study we propose a calibration ratio estimator and a calibration separate ratio-product estimator of population mean of study variable under stratified sampling using the median of auxiliary variable.

A Comparison of Model-Assisted Estimators to Infer Land Cover/Use Class Area Using Satellite Imagery

open access: yesRemote Sensing, 2014
Remote sensing provides timely, economic, and objective data over a large area and has become the main data source for land cover/use area estimation. However, the classification results cannot be directly used to calculate the area of a given land cover/

A calibrated synthetic estimator for small area estimation [PDF]

open access: yesStatistics in Transition New Series, 2021
Abstract Synthetic estimators are known to produce estimates of population mean in areas where no sampled data are available, but such estimates are usually highly biased with invalid confidence statements. This paper presents a calibrated synthetic estimator of the population mean which addresses these problematic issues.

Consequences of Departure from Normality on the Properties of Calibration Estimators [PDF]

open access: yes, 2005
This paper considers the classical and inverse calibration estimators and discusses the consequences of departure from normality of errors on their bias and mean squared error properties when the errors in calibration process are ...

New calibration estimation procedure in the presence of unit non response

open access: yesAin Shams Engineering Journal, 2023
In the present work, we have proposed the calibrated estimator of population mean in the presence of unit non response. The non response has been adjusted using the non response adjustment factor depending on different models (which are inverse linear ...

Learning to Calibrate - Estimating the Hand-eye Transformation Without Calibration Objects [PDF]

open access: yesIEEE Robotics and Automation Letters, 2021
Hand-eye calibration is a method to determine the transformation linking between the robot and camera coordinate systems. Conventional calibration algorithms use a calibration grid to determine camera poses, corresponding to the robot poses, both of which are used in the main calibration procedure.
