“…This has led to a number of promising approaches for the semi‐automated modelling of architecture and other complex objects. Approaches that perform a semi‐automated 3D reconstruction of the scene from oriented images . These approaches interactively or automatically orient and calibrate the images and afterwards perform the semi‐automated modelling relying on the human operator (Streilein, 1994; Debevec et al, 1996; El‐Hakim, 2002; Gibson et al, 2003; Guarnieri et al, 2004). Semi‐automated approaches are much more common, in particular in case of complex geometric objects.…”

“…Therefore, the IBR method is generally only used for applications requiring limited visualisation. Image‐based modelling (IBM) . This is the widely used method for geometric surfaces of architectural objects (Streilein, 1994; Debevec et al, 1996; van den Heuvel, 1999; Liebowitz et al, 1999; El‐Hakim, 2002) or for precise terrain and city modelling (Grün, 2000). In most cases, the most impressive and accurate results still remain those achieved with interactive approaches.…”

In this paper the main problems and the available solutions are addressed for the generation of 3D models from terrestrial images. Close range photogrammetry has dealt for many years with manual or automatic image measurements for precise 3D modelling. Nowadays 3D scanners are also becoming a standard source for input data in many application areas, but image-based modelling still remains the most complete, economical, portable, flexible and widely used approach. In this paper the full pipeline is presented for 3D modelling from terrestrial image data, considering the different approaches and analysing all the steps involved. IntroductionThree-dimensional (3D) modelling of an object can be seen as the complete process that starts from data acquisition and ends with a 3D virtual model visually interactive on a computer. Often 3D modelling is meant only as the process of converting a measured point cloud into a triangulated network (''mesh'') or textured surface, while it should describe a more complete and general process of object reconstruction. Three-dimensional modelling of objects and scenes is an intensive and long-lasting research problem in the graphic, vision and photogrammetric communities. Three-dimensional digital models are required in many applications such as inspection, navigation, object identification, visualisation and animation. Recently it has become a very important and fundamental step in particular for cultural heritage digital archiving. The motivations are different: documentation in case of loss or damage, virtual tourism and museum, education resources, interaction without risk of damage, and so forth. The requirements specified for many applications, including digital archiving and mapping, involve high geometric accuracy, photo-realism of the results and the modelling of the complete details, as well as the automation, low cost, portability and flexibility of the modelling technique. Therefore, selecting the most appropriate 3D modelling technique to satisfy all requirements for a given application is not always an easy task.Digital models are nowadays present everywhere, their use and diffusion are becoming very popular through the Internet and they can be displayed on low-cost computers. Although it seems easy to create a simple 3D model, the generation of a precise and photo-realistic computer model of a complex object still requires considerable effort.The most general classification of 3D object measurement and reconstruction techniques can be divided into contact methods (for example, using coordinate measuring machines,

“…New methods, such as that described by Streilein (1994), have promoted techniques for the construction of a 3D model semi-automatically and, in certain circumstances such as the capture of "data clouds", fully automatically (Newton and Mills, 1999). The amount of user input can depend on various factors such as the information supplied about the image, the required accuracy of the final model and the nature of the objects within the model.…”

The graphical representation and interactive manipulation of accurate three dimensional (3D) models of reality is rapidly becoming an inescapable necessity for many applications of geographical information systems (GIS). There are many problems and difficulties that must be overcome in order to facilitate such 3D models. Can accurate measurements, at sufficient resolution and using affordable resources, be obtained? Will application software usefully process, in all aspects, models of the real world, held in full 3D? Can a topology of containment, adjacency and contiguity in 3D be integrated into the conventional procedural and recording functionality of two dimensional (2D) GIS and still provide workable spatial analysis tools? A 3D GIS applied to an urban environment should maintain a model that would typically consist of solid representations of individual buildings, roads and utilities, providing both external and internal detail, all assigned to a suitable digital terrain model (DTM).The particular 3D application considered here addresses the need for accurate reconstruction of historical urban buildings. The creation, manipulation and exploration of such models is often referred to as "virtual heritage". Much of this paper describes an effective methodology, called the Phoenix algorithm, requiring only a single image of an urban object, for the construction of 3D models of buildings at high resolution. The development of this algorithm is discussed and the results obtained from it are compared with those obtained using traditional 3D capture techniques. An outline of further potential GIS applications is presented.

“…It uses simple photography equipment that can be customised with different settings, lenses, and lighting to suit the resolution requirements of the analysis (eg Gallo et al 2014). Additionally, methodological developments have improved time efficiency with automated and semi-automated image capture, lighting systems, and image processing (Hirschmuller and Hirschmuller 2005;Remondino 2011;Streilein 1994). Consequently, 3D photogrammetry is a cost-and time-efficient method for digital measurement, enhanced surface visualisation, and object preservation.…”

________________________________________________________________The use of 3D data in the analysis of skeletal and fossil materials has conveyed numerous advantages in many fields; however, as the availability and use of 3D scanning equipment are rapidly increasing, it is important for researchers to consider whether these methods are suitable for the proposed study. The issue of suitability has been largely overlooked in previous research; for instance, casts and reconstruction methods are frequently used to increase sample sizes, without sufficient assessment of the effect, this may have on the accuracy and reliability of results. Furthermore, the reliability of geometric morphometric methods and the implications of virtual curation have not received sufficient consideration. This paper discusses the suitability of 3D research with regard to the accuracy, reliability, and accessibility of methods and materials, as well as the effects of the current learning environment. Areas where future work will progress 3D research are proposed. ________________________________________________________________Résumé: L'utilisation de données 3D dans l'analyse de matériaux squelettiques et fossiles a fourni de nombreux avantages dans plusieurs domaines, mais comme la disponibilité et l'utilisation de l'équipement de balayage 3D connaissent une montée rapide, les chercheurs doivent se demander si ces méthodes conviennent à l'étude proposée. Le problème de la convenance a été largement ignoré dans les recherches précédentes. Pour cas, des méthodes de moulage et de reconstruction sont souvent utilisées pour augmenter la taille des échantillons sans d'abord évaluer avec précision l'effet de celles-ci sur l'exactitude et la fiabilité des résultats. Qui plus est, la fiabilité des méthodes morphométriques géométriques et les répercussions de la conservation virtuelle n'ont pas fait l'objet de suffisamment d'attention. Le présent article discute de la convenance des recherches 3D relativement à l'exactitude, la fiabilité et l'accessibilité des méthodes et matériaux, ainsi que des effets de l'environnement d'apprentissage actuel. Nous y proposons des domaines où les travaux futurs feront avancer la recherche 3D. ________________________________________________________________Resumen: El uso de datos tridimensionales en el análisis de material esqueléticos y fó siles ha proporcionado numerosas ventajas en muchos campos, sin embargo, dado que la disponibilidad y el uso de equipos de escaneo en 3D está aumentando rápidamente, es importante que los investigadores consideren si estos métodos son adecuados para el estudio propuesto.
