A flexible laser scanner system for on-line process monitoring

This paper describes a geometrical sensor system for on-line process monitoring. The sensor consists of a double ligth stripe laser scanner and a modular software for sensor data processing which have been developed in the scope of an EC ESPRIT III project. The paper presents firstly the industrial requirements revealed by a market survey and the overall system architecture. In the second part of the paper the developed novel software algorithms and an example application of the sensor system are described in detail.
