Conclusion

The first industrial applications of real-time image processing appeared in the 1980s. During this period, industrial vision systems, based mainly on specialized machines, were used more for experimental purposes, and it was only at the end of the 1990s that these vision systems reached maturity and were really used as control and measurement tools in industrial production lines.

This maturity has been achieved thanks to the evolution of the technology, marked in part by the massive arrival on the industrial market of high-resolution CCD cameras and microcomputers operating at frequencies in excess of 100 MHz. These cameras guarantee excellent image acquisition conditions, and fast, high-performance microcomputers can carry out increasingly complex image processing within a computing time compatible with industrial constraints.
