A Fast Ray-tracing Algorithm for Rugged Terrain
2019 Cross Strait Quad-Regional Radio Science and Wireless Technology Conference (CSQRWC), 2019In order to analyze coverage prediction of irregular terrain using ray tracing model, some form of accelerating must be performed to improve computational efficiency. A new image source tree structure is proposed to improving the efficiency of coverage prediction.

Rugged - Terrain Traversability Analyzing For Quadruped Robots
2019 2nd International Conference of Intelligent Robotic and Control Engineering (IRCE), 2019This paper presents an algorithm of feasibility analysis of the terrain to improve the adaptability of quadruped bionic robot for arbitrary environments. We use the depth camera to sense the ground environment, and utilize the rasterized Digital Elevation Model (DEM) to process the dense point clouds obtained by the camera to describe the terrain ...

Geohazard mitigation in remote and rugged terrain
Proceedings of the 2013 International Symposium on Slope Stability in Open Pit Mining and Civil Engineering, 2013Newmont Asia Pacific Region (APAC) operated a number of exploration tenements in Papua New Guinea, the Solomon Islands and Indonesia. A common feature to all these sites were rugged terrain, very thick vegetation canopy, high intensity rainfall and relatively young geology.

OUROBOT - a self-propelled continuous-track-robot for rugged terrain
2016 IEEE International Conference on Robotics and Automation (ICRA), 2016Adapting the concept of continuous tracks that are propelled and guided by wheels, a self-propelled continuous-track-robot has been designed and built. The robot consists of actuated chain segments, thus enabling it to change its form, independent of guiding mechanisms. Using integrated sensors, the robot is able to adapt to the terrain and to overcome

Mapping rugged terrain for a walking robot
2006This paper briefly reports on progress in the design and performance of a mapping system that uses laser rangefinder input to construct elevation maps of rugged, natural terrain. The paper emphasizes performance; the rationale for the design is presented elsewhere.

Funneling Algorithms for Multiscale Optimization on Rugged Terrains
Industrial & Engineering Chemistry Research, 2004Global optimization problems for which it is either intractable or undesirable to find all stationary points and that contain so-called “rough” or rugged objective function landscapes are studied. Such problems often show considerable differences between the small-scale (or local) geometry and the large-scale (or more global) geometry.

Atmospheric correction of satellite images over rugged terrain
2012 IEEE International Geoscience and Remote Sensing Symposium, 2012Without accurate correction of atmospheric and illumination effects, we cannot obtain physical quantity such as surface reflectance on the earth from satellite imagery. This paper proposes a new method for correcting the atmospheric effects, which variate not only horizontally but also vertically.

Path Planning of Mobile Robot Based on RRT in Rugged Terrain
Proceedings of the 2nd International Conference on Computer Science and Application Engineering, 2018The1 basic RRT algorithm is difficult to realize the path planning of 3D environment. Aiming at the 3D path planning problem of mobile robot in complex environment. An improved RRT algorithm is proposed. Firstly, the 3D environment model is established for the path planning of mobile robot under complex rugged terrain, and the task requirements are ...

Crossing the borders: from plains to rugged terrains
Exploration Geophysics, 1998We often assume that the Earth is flat and that all geophysical surveys are conducted on a flat survey plane, just as many geophysical text books suggest. However the surface of the Earth is often rugged, and the effect of this rugged surface depends directly on the height of the survey above the ground.

A generic approach to rugged terrain analysis based on fuzzy inference
ICARCV 2004 8th Control, Automation, Robotics and Vision Conference, 2004., 2005In cross-country navigation, autonomous land vehicles (ALVs) must traverse harsh natural terrains, which are uneven, rough, and sloping. One of challenges is to evaluate the terrain's characteristics quantitatively so as to prepare for smooth and stable trajectory planning subsequently.
