Robust Geometric Algorithms for Sensor Planning

چکیده
We consider the problem of planning sensor strategies that enable a sensor to be automatically con gured for robot tasks. In this paper we present robust and e cient algorithms for computing the regions from which a sensor has unobstructed or partially obstructed views of a target in a goal. We apply these algorithms to the Error Detection and Recovery problem of recognizing whether a goal or failure region has been achieved. Based on these methods and strategies for visually-cued camera control, we have built a robot surveillance system in which one mobile robot navigates to a viewing position from which it has an unobstructed view of a goal region, and then uses visual recognition to detect when a speci c target has entered the room.

Performance Evaluation of Local Detectors in the Presence of Noise for Multi-Sensor Remote Sensing Image Matching
Automatic, efficient, accurate, and stable image matching is one of the most critical issues in remote sensing, photogrammetry, and machine vision. In recent decades, various algorithms have been proposed based on the feature-based framework, which concentrates on detecting and describing local features. Understanding the characteristics of different matching algorithms in various applications ...
متن کاملQualitative Navigation by Sensor Centric Landmark Tracking
Sensor based navigation is a fundamental competence for any mobile robot. The essential problem with conventional statistical approaches to the navigation problem is the requirement for maintaining an exact global description of environment geometry. In practise the behaviour of real physical sensors and the observations they make of the environment make such central geometric representation of...
متن کاملA Qualitative Approach to Sensor Data Fusion for Mobile Robot Navigation
Sensor based navigation is fundamental to any mobile robot. Conventional statistical approaches to the navigation problem maintain an exact global description of environment geometry. However, in practise, the behaviour of real physical sensors and the observations they make of the environment make such central geometric representations extremely fragile. To overcome such problems, this paper p...
متن کاملFast and Robust Motion Planning with Noisy Data using Machine Learning
We give an overview of a new set of learningbased algorithms for fast and robust motion planning with noisy sensor data. These include improved search in configuration spaces using instance-based learning, and robust proximity queries in configuration spaces with noisy data. We demonstrate the performance of these new proximity and planning algorithms on the PR2 robot with noisy point-cloud data.
متن کاملPlanning Robust Motion Strategies for a Mobile Robot
This paper reports on a recent work we have conducted concerning the development and the implementation of a robust motion planner for a mobile robot in a polygonal environment and in presence of uncertainty in robot control and sensing. Such a planner takes explicitly into account the uncertainty in robot control and produces a robust motion plan composed of sensor-based motion commands. The m...
