Abstract
The on-line monitoring and detection of defects in laser welding is a basic manifacturing requirement in several applicative contexts, including vehicle assembly in automotive production. The speed of assembly in modern industry and the large amount of data to be acquired and elaborated pose severe real-time constraints and lead to the need of extremely short processing latencies. In this work, the implementation of time-frequency analysis algorithms on an FPGA device is shown and compared to pure software developments on different processors.
