Image-Based Lunar Surface Reconstruction
For the creation of a realistic 3 meter-sized relief globe of the Moon, a detailed height map of the entire lunar surface is required. Available height measurements of the Moon’s surface are too coarse by a factor of 15 for this purpose. The only publicly available source of high-resolution information are photographic images from the Lunar Orbiter IV mission in 1967. We present a shape-from-sh...
متن کاملConvexity in Image-Based 3D Surface Reconstruction
This work deals with the application of convex optimization techniques to the context of imagebased 3D surface reconstruction, in particular shape from silhouettes, multiview stereo and 3D segmentation. The focus is thereby not only on the optimization, but also on the design of appropriate energy functionals to be minimized. Most of the chapters of this thesis are devoted to the construction o...
متن کاملGeomorphometry – diversity in quantitative surface analysis
A widening variety of applications is diversifying geomorphometry (digital terrain modelling), the quantitative study of topography. An amalgam of earth science, mathematics, engineering and computer science, the discipline has been revolutionized by the computer manipulation of gridded terrain heights, or digital elevation models (DEMs). Its rapid expansion continues. This article reviews the ...
متن کاملMesh Optimisation for Image-Based Surface Reconstruction
A number of quite successful SFM solutions proposed focus on producing a sparse or dense set of features of the scene such as 3D points or line segments. While these representations are sometimes adequate, for many applications a more compact model is required usually in the form of solid objects or surfaces. Triangular meshes are an appealing representation because of their simplicity and the ...
متن کاملSurface reconstruction of detect contours for medical image registration purpose
Although, most of the abnormal structures of human brain do not alter the shape of outer envelope of brain (surface), some abnormalities can deform the surface extensively. However, this may be a major problem in a surface-based registration technique, since two nearly identical surfaces are required for surface fitting process. A type of verification known as the circularity check for th...
