Range imaging is a new suitable choice for measurement and modeling in many different applications. But due to the technology's relatively new appearance on the market with a few different realizations, the knowledge of its capabilities is very low. In most applications, like robotics and measurement systems, the accuracy wanted, lies at some millimeters.(More)
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(More)
In this contribution, we report on the image-based modeling (IBM) results of the Erechtheion monument, located inside the Acropolis of Athens, Greece. The work is part of the project " Development of Geographic Information Systems at the Acropolis of Athens ". An aim of the project is the 3D documentation of the whole Acropolis, one of the major(More)
The importance of landscape and heritage recording and documentation with optical remote sensing sensors is well recognized at international level. The continuous development of new sensors, data capture methodologies and multi-resolution 3D representations, contributes significantly to the digital 3D documentation, mapping, conservation and representation(More)
The generation of 3-D models from uncalibrated image sequences is a challenging problem that has been investigated in many research activities in the last decade. In particular, a topic of great interest is the modeling of realistic humans, for animation, manufacture or medicine purposes. Nowadays the common approaches try to reconstruct the human body(More)
In this paper, we first review the approaches to recover 3D shape and related movements of a human and then we present an easy and reliable approach to recover a 3D model using just one image or monocular video sequence. A simplification of the perspective camera model is required, due to the absence of stereo view. The human figure is reconstructed in a(More)
