In this paper, we propose a novel approach to stable near and long range perception for various complex outdoor environments. Our techniques cope robustly with near-range road estimation using a laser scanner and long-range terrain classification using a color camera. Near-range road surface conditions are estimated by using information of remission value as reflectivity of a laser. We apply graph...
In order to estimate landmark direction angle to localize robot in an artificial environment based on omnidirectional image, this paper introduces the method about low pass filter noise elimination, artificial landmark features detection and landmark direction angle estimation algorithms. Landmark feature detection proposed that red landmark pixels beyond the threshold were extracted as a small area...
To meet the demands of game and entertainment, autonomous humanoid robot HIT-2 is designed. Firstly, system structure of the robot is introduced. Then methods of image processing and algorithms for localization based on embedded vision system are presented. Finally, motion planning for penalty kick is carried out by the method of motion control combined with selective joints control.
This paper presents a simultaneous localization and mapping algorithm (SLAM) by using a new 3D sensor namely the photonic mixer devices (PMD). The PMD camera enables 3D image grabbing within a few milliseconds and gives an important impulse in visual 3D sensing. This camera is capable of capturing reliable depth images directly in real-time. The PMD is also compact and affordable, which makes it attractive...
The recognition and localization of objects in space is of fundamental interest in many robot vision applications, especially in those that are supposed to provide services to human beings. The trivial example of any such task is manipulation, i.e., providing a robot the means of handling objects. In this work, we discuss the chances and the problems experienced when using a time-of-flight camera...
This paper presents an autonomous off-road robot designed by converging highly reliable integrative technologies. The mechanical, electrical, and computing platforms of the robot are highly stable and easy to configure and can be used as a general robotics prototyping infrastructure for unmanned ground vehicle. Part of the design is an interactive graphical simulation interface that proved to correlate...
