Abstract

The invention discloses a loss prevention method and device, and belongs to the technical field of self-service cashier. The method comprises the steps: obtaining a video image of a cashier area; detecting hands and commodities in the video image; sub-images including the hand and the commodity in the image are extracted according to frames; according to the similarity of the front frame image and the rear frame image in the sub-images, motion trails of the hand and the commodity are obtained; according to the motion trail, the hand and the commodity are tracked; under the condition that the hand and the commodity enter the cashier area and leave again, adding one to the code scanning number; comparing the code scanning number with the number of commodities in the cash register; and when the number of the scanned codes is different from the number of the commodities, first warning information is sent out. By tracking and recognizing hands and commodities entering a cashier area, whether scanning omission and false scanning exist or not is confirmed, If yes, warning information is sent out to remind workers to pay attention.
