Abstract
A security system (10) includes an image information acquisition unit (11) that acquires input image information on an image taken of a person in a store, a tracking unit (12) that tracks an action of a hand of the person based on the input image information, and a suspicious action detection unit (13) that detects a suspicious action of the person based on the tracked action of the hand. A security system, a security method, and a security program capable of accurately detecting a suspicious action are thereby provided.
Claims18
A security system, comprising:
- a memory storing instructions;
- and
- one or more processors coupled to the memory, wherein the one or more processors are configured to execute the instructions to:
- acquire input image information of a product shelf in a store and a person in front of the product shelf taken from above the product shelf;
- detect a bone structure of the person based on the input image information;
- track the bone structure of the person;
- detect an action of a hand of the person based on the bone structure, the person being a store staff involved in the business of the store or a customer who visits the store;
- determine a suspicious action based on the action of the hand and based on whether the person is the store staff or the customer;
- and
- output alert information based on the determined suspicious action.
A security method comprising:
- acquiring input image information of a product shelf in a store and a person in front of the product shelf taken from above the product shelf;
- detecting a bone structure of the person based on the input image information;
- tracking the bone structure of the person;
- detecting an action of a hand of the person based on the bone structure, the person being a store staff involved in the business of the store or a customer who visits the store;
- determining a suspicious action based on the action of the hand and based on whether the person is the store staff or the customer;
- and
- outputting alert information based on the determined suspicious action.
A non-transitory computer readable medium storing a security program causing a computer to perform a security method, the method comprising:
- acquiring input image information of a product shelf and a person in front of the product shelf in a store taken from above the product shelf;
- detecting a bone structure of the person based on the input image information;
- tracking the bone structure of the person;
- detecting an action of a hand of the person based on the bone structure, the person being a store staff involved in the business of the store or a customer who visits the store;
- determining a suspicious action based on the action of the hand and based on whether the person is the store staff or the customer;
- and
- outputting alert information based on the determined suspicious action.
