A three-dimensional perception system for building a geometrical description of rugged terrain environments from range image data is presented with reference to the exploration of the rugged terrain of Mars. An intermediate representation consisting of an elevation map that includes an explicit representation of uncertainty and labeling of the occluded

Whole-Body Motion Planning for a Six-Legged Robot Walking on Rugged Terrain
Applied Sciences (Switzerland), 2019 Whole-body motion planning is a key ability for legged robots, which allows for the generation of terrain adaptive behaviors and thereby improved mobility in complex environment. To this end, this paper addresses the issue of terrain geometry based whole-

On Relocation of Hopping Sensors for Rugged Terrains
2010 International Conference on Computational Science and Its Applications, 2010When some sensors become power-exhausted in Wireless Sensor Networks (WSNs), mobile redundant sensors might be moved to cover the sensing holes created by the failed sensors. Within rugged terrains where wheeled sensors are unsuitable, other types of mobile sensors, such as hopping sensors, are needed.

Realization of abuttals rendering on rugged terrain
SPIE Proceedings, 2012ABSTRACT In order to combine rugged terrain and abuttals efficiently and accurately in current GIS, an improved method is presented which realized abuttals rendering on rugged terrain by the way of combining buffer object and ZP+ algorithm which comes from Z-pass.

Dynamic stability of bio-inspired biped robots for lateral jumping in rugged terrain
Applied Mathematical Modelling, 2021 Bio-inspired jumping robots should achieve stable jumping in field environment. Robots easily lose stability because of the complex terrain and large speed change.

Wind–terrain effects on the propagation of wildfires in rugged terrain: fire channelling
International Journal of Wildland Fire, 2012The interaction of wind, terrain and a fire burning in a landscape can produce a variety of unusual yet significant effects on fire propagation. One such example, in which a fire exhibits rapid spread in a direction transverse to the synoptic winds as well as in the usual downwind direction, is considered in this paper.

Rugged Terrain Effects on Diffusion
1990Recent research on diffusion in rugged terrain is reviewed, with emphasis on the Environmental Protection Agency’s (EPA) Complex Terrain Model Development Program and the Department of Energy’s (DOE) Atmospheric Studies in Complex Terrain Program. It is shown how fluid modeling studies, field experiments, and theoretical model development programs have

Interferometric DEMs in rugged terrain
IGARSS 2001. Scanning the Present and Resolving the Future. Proceedings. IEEE 2001 International Geoscience and Remote Sensing Symposium (Cat. No.01CH37217), 2002Interferometric DEMs in steep mountains are a challenge even for high coherent single pass sensors like SRTM. This work compares shadow and lay-over problems for SRTM and ERS and shows how multiple interferometric observations could be used to compute a consistent DEM of an alpine region.

Rugged terrain segmentation based on salient features
ICCAS 2010, 2010In the last decade significant progress in computer vision based control of unmanned ground vehicles (UGV) has been achieved. However, until now textural information has been somewhat less effective than color or laser range information. In this paper we propose a computer vision based cross country segmentation system that is capable of distinguishing

Magnetisation mapping in rugged terrain
Exploration Geophysics, 1998Magnetisation mapping aims to derive a map of the surface magnetisation (or equivalently, apparent susceptibility) distribution to assist in geological mapping through a more precise delineation of magnetisation boundaries and by providing a map of magnetisation levels that can be directly related to rock properties.
