Calibrating a mobile camera's parameters
Pattern Recognition, 1993Abstract The calibration of the relative rotation and translation between a camera and a mobile robot's coordinate systems is addressed, as well as the camera's intrinsic parameters, from a sequence of monocular images and robot movements. Existing hand/eye calibration procedures for robot arms are not directly applicable because they require the ...

On the method of Hunt's parameter calibration
Hearing Research, 2016This note comments on the observations of Bernier et al. (2016) regarding errors in Appendix A of Kim and Allen (2013). We acknowledge that the equations in the Appendix are in error, but wish to point out that these equations were not actually used for our analysis.

WindSat calibration and geophysical parameter estimation
IEEE International IEEE International IEEE International Geoscience and Remote Sensing Symposium, 2004. IGARSS '04. Proceedings. 2004, 2004Three aspects of WindSat performance are presented. (1). End-to-end system calibration is tested by comparisons between WindSat measurements and a robust model of the Earth TB using the vicarious cold reference method. (2). In an effort to determine probable causes for any calibration biases or scale errors that are identified, a refined Antenna ...

Calibration as parameter estimation in sensor networks
Proceedings of the 1st ACM international workshop on Wireless sensor networks and applications, 2002We describe an ad-hoc localization system for sensor networks and explain why traditional calibration methods are inadequate for this system. Building upon previous work, we frame calibration as a parameter estimation problem; we parameterize each device and choose the values of those parameters that optimize the overall system performance. This method

Grüneisen Parameter Analyzer: Calibration and Validation
Biomedical Optics 2014, 2014The Grüneisen Parameter (Γ) Analyzer, a device that can measure the energy conversion efficiency of biological samples in a photoacoustic system, is calibrated using aqueous ink dilutions. Validation of the analyzer gives Γ-ethanol= 0.72 ± 0.06.

Regularized estimators consist of two terms, one for comparing model parameters to data and one for including prior information. The tuning parameters define the weighting: small tuning parameters emphasize the data, while large tuning parameters emphasize the prior information.

Electric Parameters and Calibration of Accelerometers
Seismic Instruments, 2019The paper describes the operating principle of piezoelectric accelerometers and methods for determining their conversion factor in the time and frequency domains; the methods involve comparing simultaneous recordings of an accelerometer, a displacement sensor, a velocimeter, and a calibration shaker table.
