Department of Computer Science Activity 1998-2004
This report summarizes much of the research and teaching activity of the Department of Computer Science at Dartmouth College between late 1998 and late 2004. The material for this report was collected as part of the final report for NSF Institutional Infrastructure award EIA-9802068, which funded equipment and technical staff during that six-year period. This equipment and staff supported essentially all of the department\u27s research activity during that period

Visibility-Based Planning of Sensor Control Strategies
. We consider the problem of planning sensor control strategies that enable a sensor to be automatically configured for robot tasks. In this paper we present robust and efficient 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 specific target has entered the region. Key Words. Visibility-based planning, Error detection and recovery, Sensor configuration, Camera control, Surveillance. 1. Introduction. This paper investigates several problems in the area of visibilitybased planning of sensor control ..
