Information Processing for Image-Based Worker Time Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies lack efficient management systems for improving the management efficiency of workers in flow work processes, particularly in vehicle assembly and repair environments.
Innovation Solution
An information processing device that acquires temporal pickup images of moving work objects on a conveyance path and derives worker work times by detecting workers within a work zone using image recognition and machine learning, outputting work time information for enhanced management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual tracking methods are used to monitor worker work times, then the system complexity is low, but the management efficiency and measurement precision are insufficient
Solution Approach 1:
The patent replaces manual tracking methods with an automated image recognition system using cameras and machine learning algorithms to detect worker presence and calculate work times, thereby improving measurement precision while accepting increased system complexity through automation
Solution Approach 2:
The system uses image copies (photographs) of the work zone to detect worker presence and determine work times, eliminating the need for direct physical measurement devices and enabling non-intrusive, high-precision tracking
2Productivity
If automated image recognition systems are implemented to track worker work times, then the management efficiency and measurement precision improve, but the device complexity increases
Solution Approach 1:
The image recognition system serves multiple functions including worker detection, work time calculation, and workflow monitoring, allowing a single complex system to deliver comprehensive management improvements across multiple parameters simultaneously
Solution Approach 2:
The system automatically processes images, detects workers, calculates work times, and generates reports without requiring manual intervention, thereby improving management efficiency through automation despite the inherent complexity of the automated processes

AI summary
An information processing device includes: an acquisition unit configured to acquire a plurality of temporal pickup images of a work object that moves on a conveyance path; and a control unit configured to derive a work time of a worker from the pickup images, and to output information indicating the work time of the worker, the work time of the worker being a time during which the worker is included in a work zone around the work object while the work object is at a reference position on the conveyance path.
