Advances in sensor and GPS technologies make possible better guidance tools for vehicle/aerial navigation. In the work reported here we look at the detection of hazards, such as aircraft or other objects, on or near the target runway. Our system consists of two modules: 1) regions of interest (ROI) detection, and 2) hazard recognition. One of the harder problems in object recognition is to segm...

urnberg, Germany, May 1995. Vision-Guided Flame Control 1 Hans Burkhardt, Lars Oest, Wenjing Tao Technische Universit at Hamburg-Harburg, Technische Informatik I, Harburger Schlo str. 20, D-21071 Hamburg Abstract This paper is concerned with monitoring and control of combustion processes using image processing techniques. For closed-loop control we investigated two di erent approaches, namely ...

Accurate registration of surfaces is a common problem in computer vision. Several algorithms exist to reene an approximate value for the pose to an accurate value. They are all more or less variants of the Iterated Closest Point algorithm of Besl and McKay (1992). Up to now the problem of determining the uncertainty in the pose estimate thus obtained has not been addressed in detail. In this pa...

A mobile robot navigating in an unstructured environment faces many difficult problems for which vision may potentially offer useful solutions. The XT-1 (eXpectation based Template matching) architecture was developed in an attempt to address many of these problems with similar constructions. The current system handles such diverse problems as landmark and place recognition, the generation of o...
