Commodity Registration Imaging Zones to Prevent Duplicate Scans
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing commodity registration systems face issues with erroneous registration due to the imaging device capturing the inside of a shopping cart or basket, which can lead to multiple registrations when the quantity of commodities stored changes, especially with large or stacked items.
Innovation Solution
A commodity registration system that includes an imaging unit in the housing unit, a specifying unit to recognize commodities, a registration unit to register them, and a changing unit to adjust the recognition area based on the quantity of commodities stored, thereby reducing erroneous registrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the imaging device captures the inside of the housing unit to enable commodity recognition, then commodity registration accuracy is improved, but erroneous multiple registration occurs when commodities enter and exit the imaging area
Solution Approach 1:
The imaging area is segmented into two distinct zones: a first area for capturing commodities being placed in the housing unit, and a second area for capturing the interior of the housing unit. This spatial segmentation allows the system to differentiate between incoming commodities and stored commodities, preventing erroneous multiple registration while maintaining accurate commodity identification.
2Productivity
If the imaging area includes the inside of the housing unit to capture all commodities, then complete commodity detection is achieved, but commodities already registered may be detected again causing erroneous registration
Solution Approach 1:
The system performs preliminary classification by dividing the imaging area before commodity detection occurs. By pre-establishing the first area (for incoming commodities) and second area (for stored commodities), the system proactively prevents the harmful effect of duplicate detection before it can occur, ensuring that only commodities in the first area are registered.
3Manufacturing precision
If the imaging device is positioned to capture tray-shaped commodities from above, then stable imaging of flat commodities is achieved, but the imaging area inevitably includes the housing unit interior causing potential false detection
Solution Approach 1:
Different regions of the imaging area are assigned different functional qualities: the first area (above the housing unit) is optimized for capturing incoming tray-shaped commodities with stable top-down imaging, while the second area (inside the housing unit) is used to identify already-registered commodities. This local differentiation allows the system to maintain imaging stability while eliminating false detection through spatial functional assignment.

AI summary
Provided is a commodity registration system by which occurrence of erroneous registration of a commodity can be reduced. The commodity registration system includes: an imaging unit provided in a housing unit configured to house a commodity that is a purchase target, an inside of the housing unit being included in an imaging area; a specifying unit configured to recognize a commodity from an image captured by the imaging unit and specify the commodity to be housed in the housing unit based on the recognition result; a registration unit configured to register the commodity specified by the specifying unit as the commodity that is the purchase target; and a changing unit configured to change, based on a quantity of commodities registered by the registration unit or the image, a recognition area in the image from which the specifying unit recognizes a commodity.
