Calibration of panoramic cameras with coded targets and a 3D calibration field
(2014-01-01)
The aim of this paper is to present results achieved with a 3D terrestrial calibration field, designed for calibrating digital cameras and omnidirectional sensors. This terrestrial calibration field is composed of 139 ARUCO ...
Calibration uncertainty estimation for internal aerodynamic balance
(2008-12-01)
Aerodynamic balances are employed in wind tunnels to estimate the forces and moments acting on the model under test. This paper proposes a methodology for the assessment of uncertainty in the calibration of an internal ...

Generating virtual images from oblique frames
(2013-04-01)
Image acquisition systems based on multi-head arrangement of digital camerasare attractive alternatives enabling a larger imaging area when compared to a single framecamera. The calibration of this kind of system can be ...
Respiratory inductive plethysmography: a comparative study between isovolume maneuver calibration and qualitative diagnostic calibration in healthy volunteers assessed in different positions
(SOC BRASILEIRA PNEUMOLOGIA TISIOLOGIABRASILIA DF, 2013-08-02)
Objective: To compare two methods of respiratory inductive plethysmography (RIP) calibration in three different positions. Methods: We evaluated 28 healthy subjects (18 women and 10 men), with a mean age of 25.4 +/- 3.9 ...
