Merchandise Shelf Inventory Detection Using Camera Image Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing merchandise management systems fail to accurately determine when high-demand items need replenishment, leading to potential sales losses due to delayed inventory confirmation and replenishment.
Innovation Solution
A merchandise management device equipped with cameras to capture images of merchandise displays and a processor that detects changes in inventory levels, generating alerts when the decrease in stock exceeds a threshold, ensuring timely replenishment of high-demand items.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If store staff periodically confirm merchandise shelves manually, then the system complexity is low, but the response time to detect low inventory is delayed causing sales losses
Solution Approach 1:
The patent replaces manual mechanical inspection by store staff with an automated imaging and recognition system. Cameras capture images of merchandise shelves, and image processing algorithms automatically detect and count merchandise items, eliminating the need for periodic manual confirmation while significantly improving response time to detect low inventory levels.
Solution Approach 2:
The system enables self-monitoring of merchandise inventory levels through automated image capture and analysis. The imaging devices continuously monitor shelves and the processing unit automatically detects when merchandise levels drop below thresholds, allowing the system to inform itself of inventory status without human intervention.
2Measurement precision
If the system monitors all merchandise items equally, then the measurement coverage is complete, but the detection precision for high-demand items is insufficient leading to delayed replenishment alerts
Solution Approach 1:
The patent applies different monitoring strategies to different merchandise items based on their characteristics. High-demand items are monitored with higher precision and lower thresholds, while low-demand items use standard monitoring. This localized quality approach ensures critical items are detected accurately without uniformly increasing complexity across all merchandise.
Solution Approach 2:
The system performs preliminary classification of merchandise items to identify high-demand products before monitoring begins. This preliminary action allows the system to pre-configure appropriate detection thresholds and alert priorities for different item categories, improving detection precision for critical items without requiring complex real-time analysis for all merchandise.

AI summary
A merchandise management device is provided for a store having a first display location where a number of first merchandise is to be displayed and a second display location where a number of second merchandise is to be displayed. The merchandise management device includes cameras positioned to capture a first image indicating how many of the first merchandise is displayed at the first location and a second image indicating how many of the second merchandise is displayed at the second location, and a processor configured to detect whether or not there is a change in a displayed number of the first merchandise and a displayed number of the second merchandise, and for each merchandise item for which the change is detected, determine a degree and a direction of change and generate a replenishment alert if the degree of change in a decreasing direction is greater than a threshold.
