A Work-Related Musculoskeletal Disorders (WMSDs) Risk-Assessment System Using a Single-View Pose Estimation Model

Area of Science:

• Occupational Health and Safety
• Computer Vision
• Ergonomics

Background:

• Musculoskeletal disorders are a significant occupational health issue, particularly for manufacturing workers performing repetitive tasks.
• Current methods for assessing workplace posture may lack the detail needed for effective risk mitigation.

Purpose of the Study:

• To develop and validate a single-view 3D human pose estimation system for evaluating worker posture in manufacturing environments.
• To create a specialized dataset (DyWHSE) for manufacturing worker pose estimation and risk assessment.
• To provide quantitative guidance for improving working posture and reducing musculoskeletal risks.

Main Methods:

• Utilized single-view 3D human pose estimation with an RGB camera to capture worker posture in complex manufacturing settings.
• Developed the Duckyang-Auto Worker Health Safety Environment (DyWHSE) dataset, specific to manufacturing industry needs.
• Estimated wrist pose using the Rapid Upper Limb Assessment (RULA) method and validated the DyWHSE dataset against Human3.6M.
• Compared system performance with expert evaluations to verify applicability.

Main Results:

• Successfully developed a system capable of estimating 3D worker posture from single-view RGB images.
• Created and validated the DyWHSE dataset, demonstrating its utility for manufacturing-specific ergonomic analysis.
• The system's applicability was confirmed through comparison with expert assessments, showing reliable posture evaluation.
• The system provides quantitative data for risk assessment, aiding continuous worker posture monitoring.

Conclusions:

• The proposed 3D pose estimation system offers a practical solution for assessing and managing musculoskeletal disorder risks in manufacturing.
• The DyWHSE dataset serves as a valuable resource for research in occupational ergonomics and computer vision.
• This technology facilitates continuous posture assessment, enabling proactive interventions to enhance worker health and safety.
