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 ...
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 ...

A Self-Calibration Method of Zooming Camera
In this article we proposed a novel approach to self- calibrate a camera with variable focal length. We show that the estimation of camera’s intrinsic parameters is possible from only two points of an unknown planar scene. ...
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 ...
Digital monitoring of broiler breeder behavior for assessment of thermal welfare
(2006-12-01)
The assessment of welfare issues has been a challenge for poultry producers, and lately welfare standards needs to be reached in order to agree with international market demand. This research proposes the use of continuous ...

Avaliação experimental de técnicas de calibração de câmaras com objetiva olho de peixe
(2015-01-01)
Fisheye lens cameras enable to increase the Field of View (FOV), and consequently they have been largely used in several applications like robotics. The use of this type of cameras in close-range Photogrammetry for high ...
