A Comparative Study on Ground Surface Reconstruction for Rough Terrain Exploration
نویسنده
چکیده
Obtaining information about foreseeing terrain is an important technique for mobile robot navigation in unstructured terrain. There are several methods proposed in the literature which try to extract the geometrical models of ground surfaces efficiently. This paper categorizes the conventional ground approximation methods into three types, and presents the conceptual and performance differences thorough synthetic and real data analysis. The results demonstrate the effectiveness of previous and newly developed techniques, and also provide discussions which will be useful in the design of terrain modeling as a step of mobile robot navigation.

Rough Surface Estimation for Subsurface Imaging
In this paper a distance measurement based reflection point terrain estimation method (RPTEM) for characterizing two-dimensional (2-D) rough surfaces is presented. The method is based on the analysis of timedomain field data obtained by GPR system with Synthetic Aperture Radar (SAR) scan over 2-D rough ground surfaces. The distance from each antenna position to the ground surface is established...
متن کاملAccurate rough terrain estimation with space-carving kernels
Accurate terrain estimation is critical for autonomous offroad navigation. Reconstruction of a 3D surface allows rough and hilly ground to be represented, yielding faster driving and better planning and control. However, data from a 3D sensor samples the terrain unevenly, quickly becoming sparse at longer ranges and containing large voids because of occlusions and inclines. The proposed approac...

Mobile robots are increasingly being developed for highrisk missions in rough terrain situations, such as planetary exploration. Here a rough-terrain control (RTC) methodology is presented that exploits the actuator redundancy found in multi-wheeled mobile robot systems to improve ground traction and reduce power consumption. The methodology “chooses” an optimization criterion based on the loca...

متن کاملLearning a Terrain Model for Autonomous Navigation in Rough Terrain
Current approaches to local rough-terrain navigation are limited by their ability to build a terrain model from sensor data. Available sensors make very indirect measurements of quantities of interest such as the supporting ground surface and the location of obstacles. This is especially true in domains where vegetation may hide the ground surface or partially obscure obstacles. This thesis pre...
