Nonparametric Calibration for Depth Sensors
Robotics and Autonomous Systems, 2015 RGBD sensors are commonly used in robotics applications for many purposes, including 3D reconstruction of the environment and mapping. In these tasks, uncalibrated sensors can generate poor quality results. In this paper we propose a quick and easy to use approach to estimate the undistortion function of RGBD sensors.

On-the-field calibration of an array of sensors [PDF]
Proceedings of the 2010 American Control Conference, 2010 We address the problem of the calibration of an array of sensors by investigating theoretically and experimentally the case of 2 three-axis sensors. Our focus is on magnetometers that can be used in a low-cost inertial navigation system. Usual errors (misalignments, non-orthogonality, scale factors, biases) are accounted for.

A Calibration Algorithm for Microelectromechanical Inertial Sensors
Известия высших учебных заведений России: Радиоэлектроника, 2022 Introduction. Systematic errors of microelectromechanical (MEMS) inertial sensors, such as those related to zero drift, scale factor, and nonorthogonality of sensitive axes, are the main sources of errors in strapdown inertial navigation systems (SINS ...
