Intelligent monitoring goods theft and loss prevention method and system in warehouse management

Abstract

The invention discloses an intelligent monitoring goods theft and loss prevention method in warehouse management. The intelligent monitoring goods theft and loss prevention method employees an SSD algorithm to calculate and recognize images and interaction conditions of goods and a person in a monitoring region on the basis of video monitoring, and gives out early warning in advance when the warehouse goods are possibly stolen and lost. Specifically, The intelligent monitoring goods theft and loss prevention method comprises the following steps of: dividing a video picture into different monitoring regions according to an actual region division condition of a warehouse; then, acquiring a current frame alpha and a previous frame beta of the monitoring video, and calculating a difference ratio of the frame alpha to the frame beta; when the difference ratio exceeds a preset threshold, carrying out goods identification and human shape identification on the frame picture alpha through adopting an SSD target detection algorithm, and extracting meta-information carried by the frame picture alpha; and finally, calibrating an external rectangle A and an external rectangle B of the goods andthe human shape in the frame picture alpha according to the meta-information, and calculating whether the external rectangle A and the external rectangle B in the frame picture are overlapped in themonitoring region.

Description

technical field [0001] The invention relates to the technical field of warehouse intelligent management, and in particular to a method and system for intelligently monitoring goods to prevent theft and loss in warehouse management. Background technique [0002] At present, the intelligent management technology of warehouse storage is constantly improving, and the management methods of stored goods are getting more and more attention. For a series of processes such as warehousing, transportation, measurement, stacking and storage of goods, efficient and economical handling methods are required to reduce the loss rate of goods in each link. Especially for the theft of goods in these processes, it is necessary to have reliable measures to reduce the incidence rate, which will reduce the loss of goods in the warehouse, improve the overall efficiency of the warehouse, win the further trust of the demand side, and bring more business, etc., have an extremely effective and long-te...

AI Technical Summary

Problems solved by technology

However, the theft and loss of goods is largely carried out by internal personnel (or a combination of internal and external), and fingerprint and face recognition systems cannot solve this problem

Moreover, most of the time, thieves will not enter the warehouse from places with identification systems, which makes it even more difficult to prevent theft and damage management of goods in the warehouse.

[0009] 2) To use RFID, it is necessary to add RFID tags to the goods, and deploy RFID signal acquisition networks at appropriate locations in the warehouse area, which will be limited by warehouse construction, wiring, security, etc.

In addition, the identification distance of RFID is limited, and for some goods that do not need to be packaged (metal raw materials, etc.), the installation and removal of tags are too troublesome, and metal has a shielding effect on information, which is not suitable for warehouse scenarios. use
