Better Global Polynomial Approximation for Image Rectification
(2009-11-10)
When using images to locate objects, there is the problem of correcting for distortion and misalignment in the images. An elegant way of solving this problem is to generate an error correcting function that maps points in ...
Tree stem reconstruction using vertical fisheye images: A preliminary study
(2016-01-01)
A preliminary study was conducted to assess a tree stem reconstruction technique with panoramic images taken with fisheye lenses. The concept is similar to the Structure from Motion (SfM) technique, but the acquisition and ...
Indice de vegetacao e modelo linear de mistura espectral no monitoramento da regiao do pantanal.
(Pesquisa Agropecuaria Brasileira, Brasilia, v.33, p.1729-37, out.1998., 2011)
Bounded biharmonic blending of Möbius transformations for flexible omnidirectional image rectification
(2020-12-01)
We propose a new method to correct distortions in equirectangular images, i.e., images that use the longitude/latitude representation to describe the full spherical field of view around a given viewpoint. We show that ...
Formação de imagens multiespectrais por meio de fusão de imagens adquiridas por múltiplas câmaras
(Universidade Estadual Paulista (Unesp), 2010-05-27)
A utilização de imagens adquiridas por sensores CCD de médio formato, em plataformas aéreas, é uma alternativa para a redução de custos em projetos de aerolevantamento. Porém, alguns inconvenientes, como a pequena área de ...
USING RELATIVE ORIENTATION CONSTRAINTS TO PRODUCE VIRTUAL IMAGES FROM OBLIQUE FRAMES
(Copernicus Gesellschaft Mbh, 2012-01-01)
Image acquisition systems based on multi-head arrangement of digital cameras are attractive alternatives enabling larger imaging area when compared to a single frame camera. The calibration of this kind of systems can be ...

A system for beach video-monitoring: Beachkeeper plus
(Pergamon-Elsevier Science Ltd, 2012-12)
A suitable knowledge of coastal systems, of their morphodynamic characteristics and their response to storm events and man-made structures is essential for littoral conservation and management. Nowadays webcams represent ...
REGISTRATION AND FUSION OF MULTIPLE IMAGES ACQUIRED WITH MEDIUM FORMAT CAMERAS
(Copernicus Gesellschaft Mbh, 2010-01-01)
Recent developments in the technology of optical digital sensors made available digital cameras with medium format at favourable cost/benefit ratio. Many companies are using professional medium format cameras for mapping ...
