Geometric Calibration of a Hyperspectral Frame Camera
(2016-09-01)
Recently, miniaturised hyperspectral sensors operable from small unmanned airborne vehicle platforms have entered the market. The emerging hyperspectral imaging technologies, based on frame cameras and tuneable filters, ...
A influência das injunções de orientação relativa na calibração de um sistema dual de câmaras digitais
(2009-10-21)
Image acquisition systems based on multi-head arrangement of digital frame cameras, such as the commercial systems DMC, UltraCam, besides others, are attractive alternatives enabling larger imaging area when compared to a ...
Line based camera calibration in machine vision dynamic applications
(1999-12-01)
The problem of dynamic camera calibration considering moving objects in close range environments using straight lines as references is addressed. A mathematical model for the correspondence of a straight line in the object ...
The influence of subpixel measurement on digital camera calibration
(2012-09-10)
The aim of this work is to evaluate the influence of point measurements in images, with subpixel accuracy, and its contribution in the calibration of digital cameras. Also, the effect of subpixel measurements in 3D coordinates ...
Robust Extrinsic Camera Calibration from Trajectories in Human-Populated Environments
(Revista Computación y Sistemas; Vol. 16 No. 1, 2012-03-05)
Abstract. This paper proposes a novel robust approach
to perform inter-camera and ground-camera calibration
in the context of visual monitoring of human-populated
areas. By supposing that the monitored agents evolve
on ...
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 ...
