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 ...
Camera calibration using detection and neural networks
(2013-01-01)
Several applications use robotic vision, such as a robot navigating through an unknown surrounding, can use vision as main navigate sensor. This paper focuses on studying camera calibration via stereo vision by means of ...
Automatic Calibration Of Low Cost Inertial Gyroscopes With A Ptu
(IEEENew York, 2016)
Refining the geometric calibration of a hiperspectral frame camera with preliminary bands coregistration
(2018-10-31)
Lightweight hyperspectral sensors carried by unmanned aerial vehicles (UAV) are becoming powerful remote sensing tools for several applications, e.g., forestry and agriculture. Sequential frame acquisition by scanning the ...
REFINING THE GEOMETRIC CALIBRATION OF A HIPERSPECTRAL FRAME CAMERA WITH PRELIMINARY BANDS COREGISTRATION
(Ieee, 2018-01-01)
Lightweight hyperspectral sensors carried by unmanned aerial vehicles (UAV) are becoming powerful remote sensing tools for several applications, e.g., forestry and agriculture. Sequential frame acquisition by scanning the ...
A low cost structured light system
(2005-12-01)
The aim of this paper is to present the current development status of a low cost system for surface reconstruction with structured light. The acquisition system is composed of a single off-the-shelf digital camera and a ...
Screen-printed carbon electrode modified with poly-L-histidine applied to voltammetric determination of chromium (VI)
(2006-12-01)
The present work reports the use of a screen-printed carbon electrode (SPCE) modified by poly-L-histidine film to determine chromium (VI). Stable films can be formed by direct addition of PH solution 1 % (w/v) on the ...
Comparison of the GEANT4 releases 8.2 and 9.2 in terms of a pCT reduced calibration curve
(2010-12-01)
The GEANT4 simulations are essential for the development of medical tomography with proton beams pCT. In the case of thin absorbers the latest releases of GEANT4 generate very similar final spectra which agree well with ...
