Variable Resolution Terrain Surfaces
A model for the multiresolution decomposition of planar domains into triangles is introduced, which is more general than other multiresolution models proposed in the literature, and can be eeciently applied to the representation of a polyhedral terrain at variable resolution. The model is based on a collection of fragments of plane triangulations arranged into a partially ordered set. Diierent ...
متن کاملMap Building for a Terrain Scanning Robot
This paper presents the application of an image registration method for a mobile manipulator. The robot is used for scanning natural terrain and detecting metal objects hidden beneath the terrain surface (e.g., landmines) using a metal detector. The range image may be interpreted for visual servoing, map building and path planning, or object recognition. In this work, the image is used to build...
متن کاملHigh Resolution Modelling in Complex Terrain
During the past years the modelling community, both from the application and pure research perspectives, has been facing the challenge of high-resolution modelling in places with complex topography. In February 2012, as a result of the collaborative efforts of BOKU-Met, ARSC, IMG and the enthusiasm of the scientific community, the HiRCoT workshop was held in Vienna. HiRCoT objectives were: 1) T...
متن کاملOut-of-core Multi-resolution Terrain Modeling
In this chapter we discuss issues about Level Of Detail (LOD) representations for digital terrain models and, especially, we describe how to deal with very large terrain datasets through out-of-core techniques that explicitly manage I/O operations between levels of memory. LOD modeling in the related context of geographical maps is discussed in Chapters 3 and 4. A dataset describing a terrain c...
متن کاملA Multi-resolution Representation for Terrain Morphology
Mesh-based terrain representations provide accurate descriptions of a terrain, but fail in capturing its morphological structure. The morphology of a terrain is defined by its critical points and by the critical lines joining them, which form a so-called surface network. Because of the large size of current terrain data sets, a multi-resolution representation of the terrain morphology is crucia...
