Solution Overview
Problem
Existing store systems require significant changes and the installation of multiple cameras to achieve automatic commodity registration across an entire store, resulting in a substantial burden on retailers.
Innovation Solution
A registration device equipped with a sensor-enabled shelf, cameras, and a processor that tracks customers and determines commodity purchase registration based on customer actions and weight changes measured by the sensor, allowing for minimal changes to existing store systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a store system uses multiple cameras and changes store layout to achieve automatic commodity registration, then automatic registration processing can be achieved, but the installation complexity and burden on the store side increases significantly
Solution Approach 1:
The patent divides the store into multiple detection zones (first detection zone near the shelf and second detection zone further away) and uses separate detection means for each zone. The registration determination unit processes information from both zones to determine commodity registration, allowing the system to achieve automatic registration without requiring comprehensive camera coverage of the entire store, thus reducing installation complexity while maintaining automation.
2Measurement precision
If a store system installs multiple cameras and changes store layout for automatic registration, then commodity registration accuracy improves, but the cost and burden on retailers increases
Solution Approach 1:
The patent introduces a weight sensor as an intermediary detection means placed on the shelf. When a commodity is placed on the shelf, the weight sensor detects the weight change and generates detection information. This intermediary device works in conjunction with the camera system to accurately determine commodity registration without requiring complex multi-camera setups, thereby improving registration accuracy while controlling system complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables efficient and automatic commodity registration with reduced installation complexity, allowing retailers to implement the system with smaller changes to their existing infrastructure.
Implementation Method 1
determine whether the commodity has been taken from the shelf based on changes in weight measured by the sensor

AI summary
A registration device includes a shelf including a sensor and on which a commodity is placed, a camera configured to capture an image of a first area and a second area outside the first area, and a processor configured to start tracking of a customer who has entered the second area from outside based on the image captured by the camera, determine whether the commodity is taken from the shelf based on changes in weight measured by the sensor, upon determining that the commodity has been taken, determine whether the tracked customer performs a particular action within the first area, upon determining that the tracked customer has performed the particular action, determine whether the customer has entered the second area, and upon determining that the customer has entered the second area, register the taken commodity as a commodity being purchased by the customer.
