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 ...
Using relative orientation constraints to produce virtual images from oblique frames
(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 ...
Application of the photogrammetric and the geographic information systems in the urban environment: A case of study
(2002-01-01)
The urban growth and the environmental relationship are several times joint as to the of the urban soil occupation as to the urban area development. The transformation of the several kinds of soil use and the human being ...

(2019-06-04)
Currently on the world market there are several models and manufacturers of RPAS-UAV. This equipment made it possible to complete the entire flow of the photogrammetric mapping process in teaching for the students of the ...
Strategy to detect ground control in digital images
(Spie - Int Soc Optical Engineering, 1998-01-01)
The identification of ground control on photographs or images is usually carried out by a human operator, who uses his natural skills to make interpretations. In Digital Photogrammetry, which uses techniques of digital ...
Automatic absolute orientation of scanned aerial photographs
(Institute of Electrical and Electronics Engineers (IEEE), Computer Soc, 1998-01-01)
Image orientation is a basic problem in Digital Photogrammetry. While interior and relative orientations were succesfully automated, the same can not be said about absolute orientation. This process can be automated by ...
