Orientation and reconstruction of close-range images using lines
(2000-01-01)
The aim of this paper is to present two problems where straight lines were used as the primary source of control. The first problem is the orientation of images using vertical and horizontal lines for flat surface monoplotting. ...
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 ...
Reduced calibration curve for proton computed tomography
(2010-08-26)
The pCT deals with relatively thick targets like the human head or trunk. Thus, the fidelity of pCT as a tool for proton therapy planning depends on the accuracy of physical formulas used for proton interaction with thick ...
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 ...
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 ...
A study on the variations of inner orientation parameters of a hyperspectral frame camera
(2018-09-20)
New low-cost hyperspectral frame sensors have created a new perspective for remote sensing applications. In this work, we investigate some issues related to the geometric calibration of a hyperspectral frame camera based ...
Development of a new TDR probe for determining soil water content and dry density
(2007-09-18)
A few traditional methods for determining water content in the field are either inaccurate or time consuming. As an alternative, the time domain reflectometry (TDR) technology has been used in the determination of the soil ...
3D Reconstruction of Citrus Trees Using an Omnidirectional Optical System
(2020-03-01)
This paper presents a feasibility study on the use of omnidirectional systems for 3D modelling of agricultural crops, aiming a systematic monitoring. Omnidirectional systems with multiple sensors have been widely used in ...
