Multi-channel supported surveying of industrial floor tiles

Within the building industry, there is an increasing trend towards automation for various reasons. The modelling of human intuitive abilities and the handling of building materials with increasing dimensions leads to some problems in the necessary sensor technology. This paper deals with a technical treatment of the multi-channel acquisition of floor tiles within a system for large-area automated tile laying. Concrete detecting problems of large-format building materials are dealt with and a possibility is presented to determine necessary parameters for a pick and place system. There is a whole systematic description of the measurement system design, including preinvestigation and spectral aspects. Special attention is given to the optimization of the image-based recognition system, edge detection and the elimination of environmental influences. In the last part, the necessity for a multichannel system is presented and its implementation is explained.
