Purdue Experiments in Model-based Vision for Hallway Navigation
نویسنده
چکیده
In the Robot Vision Laboratory of Purdue University , we have developed two robust architectures for vision-guided mobile robot navigation in indoor environments. The rst approach, FINALE, enables the robot to autonomously navigate in hallways at speeds around 8m=min through vision-based position-updating, utilizing a geometrical map, model-based reasoning and Kalman ltering. The performance of the navigation is not impaired by the presence of stationary or moving obstacles. The second approach, FUZZY-NAV , performs vision-based navigation in a more human-friendly manner, utilizing simply a topo-logical map and the combination of neural networks and fuzzy logic. This approach also allows the robot to simultaneously navigate and avoid obstacles, both static and dynamic. In this paper, we describe the above two approaches and show experimental results to demonstrate the eeectiveness and the robustness of our approaches.

Vision-based navigation of mobile robot with obstacle avoidance by single camera vision and ultrasonic sensing
This paper describes a vision-based navigation method in an indoor environment for an autonomous mobile robot which can avoid obstacles. In this method, the self-localization of the robot is done with a model-based vision system, and a non-stop navigation is realized by a retroactive position correction system. Stationary obstacles are avoided with single-camera vision and moving obstacles are ...

In this paper, we present the results of a hierarchical SLAM/GPS/INS/WLFP sensor fusion to be used in navigation system devices. Due to low quality of the inertial sensors, even a short-term GPS failure can lower the integrated navigation performance significantly. In addition, in GPS denied environments, most navigation systems need a separate assisting resource, in order to increase the avail...
