Terrain analysis from curvature profiles
International Journal of Imaging Systems and Technology, 1990AbstractThis paper describes a new algorithm which uses Gaussian and mean curvature values of the terrain surface to extract feature points. These points are then used for recognition of particular subregions of the terrain and in estimating relative positions of these subregions in the terrain.

Performance analysis and terrain classification for a legged robot over rough terrain
2012 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2012Minimally actuated millirobotic crawlers navigate unreliably over uneven terrain-even when designed with inherent stability-mostly because of manufacturing variabilities and a lack of good models for ground interaction. In this paper, we investigate the performance of a legged robot as it traverses three distinct rough terrains: tile, carpet, and ...

Terrain analysis and locomotion control of a hexapod robot on uneven terrain
2014 9th IEEE Conference on Industrial Electronics and Applications, 2014A terrain analysis method with a scanning laser range finder was proposed. For five typical kinds of terrain, including flat ground, vertical wall, slope, step and cuboid obstacle, the method can distinguish them successfully. Comparing with some methods used cameras, it's more simple and has less calculation.

Incremental terrain visibility analysis
SPIE Proceedings, 2006Visibility analysis is an important aspect in terrain analysis. Terrain visibility calculation is a time-consuming process, and visibility algorithms are dedicated to reduce the algorithm complexity to enhance calculation speed. We use digital elevation model to represent terrain.

Scale dependence in terrain analysis
Mathematics and Computers in Simulation, 1997Abstract Topographic attributes computed from digital elevation models are dependent on the resolution of the elevation data from which they are computed. A regular rectangular grid is not an ideal representation of topographic surfaces for the study of scale effects.
