Worker Appearance-Based Work History Estimation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies do not effectively support the optimization of the entire work process in a work region where one or multiple workers are engaged.
Innovation Solution
A management apparatus and system that includes a master storage unit for associating predetermined worker appearances with types of work, and an estimation unit that analyzes video footage of the work region to estimate the type of work being conducted by each worker based on their appearance and the stored master information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If video analysis is performed to recognize worker appearance and work types, then work history information can be automatically collected and management efficiency is improved, but the complexity of the management system increases due to the need for video analysis capabilities and master information storage
Solution Approach 1:
The system performs preliminary action by pre-storing master information that associates worker appearances with work types before actual work history collection. This pre-prepared reference data enables the video analysis unit to quickly match observed workers with their corresponding work activities, automating the collection process without requiring complex real-time decision-making logic
Solution Approach 2:
The master information acts as an intermediary between the video analysis unit and the work history information storage. It serves as a reference bridge that translates visual observations of workers into structured work history data, simplifying the overall system architecture by decoupling the video analysis function from the history storage function
2Measurement precision
If the management apparatus stores detailed master information associating worker appearances with work types, then estimation accuracy of work types is improved, but the information storage requirement and system complexity increase
Solution Approach 1:
The master information is organized with local quality by creating specific associations between particular worker appearances and their corresponding work types. Rather than storing generic worker data, the system stores targeted appearance-work type pairs that are locally optimized for accurate identification in the specific work environment, improving estimation accuracy without unnecessary storage overhead

AI summary
A management apparatus (102) includes a master storage (103) for storing master information (103a), and an estimation unit (104). The master information (103a) associates, with each other, an appearance predetermined for one worker or a worker group who conducts work and a kind of the work. The estimation unit (104) estimates a kind of work conducted by each of one or a plurality of workers, based on appearance information about an appearance of the one or the plurality of workers being acquired by analyzing a video in which a work region is captured, and the master information (103a).
