Expertensysteme zur Datenanalyse technischer und ökologischer Multisensorsysteme

For the evaluation of a multisensor system we design a prototype of an expert system which is based on a causal probabilistic network. Using stochastic cause-effect relations, with such an expert system it is possible to reduce uncertainty about the evaluation of some sensors by introducing evidence from other sensors. In traffic guidance systems a LIDARsensor may be used to detect obstacles and to determine visibility. We show how the visibility may be obtained from the LIDAR signal using additional knowledge from the other sensors and the inference system of the expert system.
