METHOD (VARIANTS) AND DEVICE (VARIANTS) FOR AUTOMATED DETECTION OF INTENTIONAL OR INCIDENTAL DISRUPTIONS OF TECHNOLOGICAL PROCEDURE BY OPERATOR

摘要

FIELD: surveillance equipment, in particular, analysis of image, produced by an optical or different type of device.;SUBSTANCE: in a shop, video surveillance or motion detection or presence detection means are used, and also purchase registration means, routes of movement of hands of operator and/or product, corresponding to conduction of technological operation, are analyzed, most characteristic ones are singled out, areas of movement detection of detection of presence of operator hands and/or goods are selected. Detected routes are described in form of scenarios which represent a set of time-ordered events, including influx of signals from presence and motion control areas, with consideration of their time relations. Influx of signals from observed areas is detected. Signals are combined in a series and compared to available scenarios. On coincidence of a received series of signals with one or more scenario, receipt of signal from operation completion sensor during a time interval, determined by that scenario, is checked. In case of absence of signal from operation completion sensor the operation is classified as incorrectly performed, and actions of operator are classified as abuse.;EFFECT: detection of incorrect actions of operator with allowed frequency of false activations.;8 cl, 7 dwg
