Automatic space resection using a constrained relational matching
(2000-01-01)
Image orientation is a basic problem in Digital Photogrammetry. While interior and relative orientations have been successfully automated, the absolute orientation (or space resection) continues to be an important topic ...
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 ...
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 ...
Rpas in the support for photogrammetry education: Cases in topographic mapping and documentation of historical monuments
(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 ...
Registration and fusion of multiple images acquired with medium format cameras
(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 ...
Accuracy assessment of a photogrammetric close-range reconstruction system
(Institute of Electrical and Electronics Engineers (IEEE), Computer Soc, 1998-01-01)
Geometric accuracy of a close-range photogrammetric system is assessed in this paper considering surface reconstruction with structured light as its main purpose. The system is based on an off-the-shelf digital camera and ...

Building roof contour extraction from LiDAR data
(2011-12-01)
This paper proposes a method for the automatic extraction of building roof contours from a LiDAR-derived digital surface model (DSM). The method is based on two steps. First, to detect aboveground objects (buildings, trees, ...
Methodology for Land Mapping of Amapa State-A Special Case of Amazon Radiography Project
(2020-09-26)
The Brazilian Amazon has been mapped by the Brazilian Army Geographic Service (DSG) on the Amazon Radiography project using synthetic aperture radar (SAR) technology. The Amapa State is a special case of this project because ...
