UAV (Unmanned Aerial Vehicle) photogrammetry, which combines UAV and freely available internet-based 3D modeling software, is widely used as a low-cost and user-friendly photogrammetry technique in the fields such as remote sensing and geosciences. In UAV photogrammetry, only the platform used in conventional aerial photogrammetry is changed. Consequently, 3D modeling software contributes signi...

Abstract. The present work introduces a new low-cost prototype® designed for photogrammetric surveys of small objects, using single photographic shot. utilizes the different perspectives object presented by series mirrors strategically placed in camera sensor. set specular reflections projected on our sensor simulates same effect as taking pictures from equivalent points each mirror.The v1 was ...

Experiences and recent developments of a WEB application dedicated to digital photogrammetry are presented. The aim of the ARPENTEUR project (as Architectural PhotogrammEtry Network Tool for EdUcation and Research) is to propose a photogrammetric concept and software embedded in Web technology and Java programming language. Photogrammetry and 3D modeling tools are available on the Internet with...

Permission is granted to quote short excerpts and to reproduce figures and tables from this report, provided that the source of such material is fully acknowledged. Abstract. In this paper, we show that a 3D laser scanner tracking system can be efficiently used in a projective mode similar to photogrammetry-based methods. The best of both laser ranging and photogrammetry can be combined to incr...

The presented research investigates the application of close-range photogrammetry surveying techniques and Augmented Reality (AR) visualization to design a semi-automated method for rapidly measuring structural damage induced in tall buildings by seismic events such as earthquakes or explosions. Close-range photogrammetry algorithms were designed to extract spatial information from photographic...

3D models of building components or construction resources have been largely created by computer-aideddesign (CAD) or by proprietary code for virtual reality development. Such 3D modeling methods entail accurate definition of points, lines and their relationships in the spatial coordinate system. Unlike CAD modeling, the surveying technique of photogrammetry takes a completely different approac...

Motivated by results on the mobility of mechanical devices called pentapods, this paper deals with a mathematically freestanding problem, which we call Möbius Photogrammetry. Unlike traditional photogrammetry, which tries to recover a set of points in three–dimensional space from a finite set of central projection, we consider the problem of reconstructing a vector of points in R3 starting from...

Close-range photogrammetry has been used in many applications in recent decades in various fields such as industry, cultural heritage, medicine and civil engineering. As an important tool for displacement measurement and deformation monitoring, close-range photogrammetry has generally been employed in industrial plants, quality control and accidents. Although close-range photogrammetric applica...
