As the world we are living in is three or more dimensions, we have to reconstruct the world in three dimension (3D). However, the world is composed of various things which have different modes, states and attributes. In certain applications, the emphases are put on certain special objects, it is unpractical and unnecessary to describe and express them in a way. Therefore we just need to construct...
Three-dimensional (3D) reconstruction considering of image sequences is an unresolved and active research topic on the cross-section of computer vision and digital photogrammetry. In this paper, we focus on 3D object shape reconstruction from uncalibrated images and put forward a rapid algorithm to recover the object height. The recovering 3D shape comprises two steps, for the one hand, calculate...
3D reconstruction from uncalibrated image sequences is very important technology in computer vision. However, we only get 3D point cloud reconstructed from the image sequence, so the paper puts forward a kind of 3D reconstruction method considering of image sequences combined with 3D models taking advantages of parallel lines and vertical lines in features extracting. The experiment shows that the...
With the development of the Internet, the need of city 3D data is rising more and more, and the emphasis shifts from analysis to the sharing of city 3D data and information over the Internet. In Internet, we lack uniform 3D data standard and 3D data cannot be shared and exchanged availably. The city Geography Mark-Up Language (GML) was developed as the standard language for exchanging and sharing...
