Measuring photogrammetric control targets in low contrast imagesMedição de alvos fotogramétricos em imagens com baixo contraste
(2018-04-01)
This paper presents an experimental assessment of photogrammetric targets and subpixel location techniques to be used with low contrast images such as images acquired by hyperspectral frame cameras. Eight different target ...
Optimization of temperature, targets, and illumination for high precision photogrammetric camera calibration
(2017)
MOONS, Multi-Object Optical and Near-Infrared Spectrograph, será un instrumento para uno de los telescopios de 8.2m del Very Large Telescope de ESO. Este estudiará el espectro de 1000 objetos celestes en un campo de vista ...
Automatic Orientation of Multi-Scale Terrestrial Images for 3D Reconstruction
(Mdpi Ag, 2014-04-01)
Image orientation requires ground control as a source of information for both indirect estimation and quality assessment to guarantee the accuracy of the photogrammetric processes. However, the orientation still depends ...
A low-cost 3D reconstruction system using a single-shot projection of a pattern matrix
(Wiley-Blackwell, 2011-03-01)
The purpose of this work is to present the main features of a structured light system and some experimental results. The system, named SingleShot3DSL, is based on a single off-the-shelf digital camera and a pattern projector. ...

Reconstruction of cylindrical surfaces using digital image correlation
(2018-12-01)
A technique for the reconstruction of cylindrical surfaces using optical images with an extension of least squares matching is presented. This technique is based on stereo-image acquisition of a cylindrical object, and it ...
