Vision-Based Clutter Detection in Retail Spaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Retail environments, particularly fast food restaurants, face challenges in efficiently monitoring and maintaining customer space cleanliness and service quality through existing surveillance technologies, which lack effective automated systems for detecting clutter and notifying staff in real-time.
Innovation Solution
A vision-based system that uses existing surveillance cameras to detect regions of interest in customer spaces, such as dining areas, by analyzing visual data for predefined clutter conditions like relocated objects or sustained absence of motion, and generates notifications to staff when these conditions are met, utilizing object detection algorithms and computer vision techniques to identify specific objects and determine the need for cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If automated vision-based clutter detection system is implemented, then monitoring precision and response time are improved, but device complexity increases
Solution Approach 1:
The system uses existing surveillance camera networks for multiple purposes: traditional security monitoring and the new clutter detection function. By making the surveillance infrastructure multi-functional, the patent avoids deploying separate dedicated cameras for clutter monitoring, thereby reducing overall system complexity while achieving precise clutter detection through software-based computer vision algorithms
Solution Approach 2:
The patent replaces manual monitoring (human employees visually checking for clutter) with automated computer vision algorithms. This substitution of mechanical/manual processes with optical-digital processing enables precise automated detection without requiring additional physical monitoring devices, resolving the contradiction between detection precision and system complexity
2Productivity
If real-time monitoring of all customer spaces is implemented, then productivity and customer experience are improved, but energy consumption increases
Solution Approach 1:
Instead of uniformly monitoring all customer spaces with the same intensity, the system applies monitoring selectively to specific regions of interest where clutter is most likely to occur and impact customer experience. The computer vision algorithms focus computational resources on identified problem areas rather than processing every pixel in every frame across the entire facility, thereby improving cleaning efficiency while reducing energy consumption
Solution Approach 2:
The system uses motion detection to trigger clutter analysis only when relevant activity is detected, rather than continuously analyzing all areas. This periodic activation based on motion events reduces computational energy consumption while maintaining high productivity by immediately notifying staff when clutter conditions are detected during customer activity periods
3Ease of operation
If manual monitoring of clutter is eliminated, then labor costs are reduced, but reliability of detection may worsen
Solution Approach 1:
The system enables self-service monitoring where the surveillance infrastructure and computer vision algorithms automatically perform the clutter detection function without human intervention. The existing cameras and processing systems serve themselves to identify and report clutter conditions, eliminating the need for dedicated manual monitors while maintaining reliable detection through automated algorithmic analysis
Solution Approach 2:
The system implements feedback loops where detection results are immediately communicated to staff through notifications, and the system can be trained and adjusted based on detected patterns. This feedback mechanism ensures reliable detection by continuously improving the accuracy of the computer vision algorithms and maintaining system performance over time without requiring manual monitoring
Data Source
AI summary
A system and method of monitoring a customer space including obtaining visual data comprising image frames of the customer space over a period of time, defining a region of interest within the customer space, the region of interest corresponding to a portion of the customer space in which customers relocate objects, monitoring the region of interest for at least one predefined clutter condition, and generating a notification when the at least one predefined clutter condition is detected.
