Methods of digital photogrammetry depict a suitable tool for the automatic measurement of twoand three-dimensional displacements fields, deformations and surface defects such as cracks of test objects and structures during short and long time load tests. The paper gives an overview on recent research and development activities in the field of civil engineering material testing, conducted by the...

This paper describes the project of the Close Range Photogrammetry and Remote Sensing Group, University of Vigo, Spain, involving historic arch bridges in Galicia, Spain. The first aim of this Project consists on building a database of the historic arch bridges in Galicia, documenting location, surroundings, geometry, singular characteristics, structural faults, building material and state of c...

A priori object information like parallelism and perpendicularity can be very useful for 3D-reconstruction, especially in architectural photogrammetry. With digital close-range imagery parallelism of object lines can be exploited by applying automatic vanishing point detection. This image analysis technique allows the detection of parallel object lines and leads to their spatial orientation in ...

Camera calibration has always been an essential component of photogrammetric measurement, with self-calibration nowadays being an integral and routinely applied operation within photogrammetric triangulation, especially in high-accuracy close-range measurement. With the very rapid growth in adoption of off-the-shelf digital cameras for a host of new 3D measurement applications, however, there a...

This paper presents a basic theory of intelligent photogrammetry and corresponding physically independent agent systems named Photogrammetron. Intelligent photogrammetry is a fusion of ideas, techniques and applications from digital photogrammetry, active vision and intelligent agents, aiming at developing highly automatic and intelligent photogrametric systems. The tenet of intelligent photogr...

In recent years, considerable developments have occurred in the field of digital photogrammetry. These have been due mainly to increases in computing power, the refinement of featureand area-based image matching algorithms and the reduction in the cost of equipment capable of producing near real-time images in digital format. A major limitation to the widespread application of digital photogram...

Three-dimensional (3D) real scale models delivered from digital photogrammetric techniques have rapidly increased to meet the requirements of many applications in different fields daily life. This paper deals with establishment a 3D model block images (18 images) that were captured by using Canon EOS 500D camera cover test field area consisting 90 artificial target points, 25 them are ground co...

The global management of complex urban environments require flexible Information Systems able of adapting to different needs of private and institutional agents related to preservation and sustainability of Cultural Heritage. Heterogeneity of formats and sources makes difficult the transfer of digital information, which is increased by nontextual support. 3D models provide a support enabling re...
