We present a simple and intuitive method for interactive 3D reconstruction and camera calibration from a single image of a structured scene. The method is based on manual registration of two world planes. We present experimental results on some test images.

We consider dynamic scenes consisting of moving points whose motion is constrained to happen in one of a pencil of planes. This is for example the case when rigid objects move independently, but on a common ground plane (each point moves in one of a pencil of planes parallel to the ground plane). We consider stereo pairs of the dynamic scene, taken by a moving stereo system, that allow to obtai...

Surveillance of public environments, and in particular of museum rooms, is an important activity that requires the use of different computer and telecommunication technologies. In this paper we describe a semi-automatic surveillance system that is based on a 3D reconstruction of a museum environment, obtained by a stereo vision system, that allows for detecting those situations that are conside...

This paper presents a 3D reconstruction technique for real world environments based on a traditional 2D laser range finder modified to implement a 3D laser scanner. The paper describes the mechanical and control issues addressed to achieve physically the 3D sensor as well as the adaptation of some previously developed techniques used to merge range and intensity data and illustrates the potenti...

This thesis proposal addresses the 3D reconstruction from feature correspondences among many images. An introduction to the reconstruction problem is given at the beginning. Then, the State-of-the-Art in the field of 3D reconstruction is presented. Our previous research related to this field is described. Finally, the thesis goals are formulated.

A new algorithm for 3D reconstruction of twodimensional crystals from projections is presented, and applied to biological macromolecules imaged using electron microscopy. Its main departure from the traditional approach is that it works in real space, rather than in Fourier space, and is iterative. This approach has the advantage of making it convenient to introduce additional constraints (such...

3D reconstructions allow cultural institutions such as museums and historic sites a tool to vividly illustrate the past while educating the public about competing interpretations of history and change over time. 3D technology also offers many practical benefits including low cost, flexibility, and the potential for collaboration. This paper presents potential applications of 3D reconstructions ...

Archaeological data collection is based on the description of archaeological contexts. An archaeological excavation demolishes the original matrix within which the cultural material is found and special care is taken to record spatial context. Each artifact is described in terms of its physical and spatial properties as well as its relation to the matrix (for example soil composition). As sever...

A concise derivation is given for a compact nonlinear equation which specifies possible 3D rotations of rigid objects, compatible with measurements of five object points in two views. The insight provided by direct geometrical interpretation of this equation = which contains ULLMAN's polar equation as a special case-may be exploited for attempts to categorize the set of possible solutions.
