Paper Abstract

A description of machine sight system developed at IA&E of the Siberian Branch of RAS intended for the control of crystals cultivation process is given. The work of the system is based on digital processing of optical signals (images) registered by digital video cameras with linear photoreceivers. The algorithms of processing are developed which secure receipt of the melting level estimations, diameter of a crystal, width of the zone of meniscus. The metrological characteristics of system are given; the results of its testing and perspective variants of realization are analyzed.
