مقدمه
This study delves into revolutionizing postural load assessment methodologies by employing an RGB camera, diverging from the traditional Kinect™ range sensor. The focus lies in integrating machine learning techniques to process data gleaned from the RGB camera, fostering a deeper understanding of diverse postures. Recognizing the pivotal role of accurate posture assessment in ergonomic analyses, an adapted OWAS ergonomic assessment system was employed. This system facilitated the acquisition of data from the RGB camera, fostering insights into posture-associated risk levels. The study aimed to scrutinize the impact of the camera's viewing angle on posture classification accuracy concerning human observer assessments.
مواد و روشها
The research methodology involved the adaptation of an OWAS ergonomic assessment system to gather data through an RGB camera for posture analysis. Leveraging machine learning, the collected data underwent processing to delineate posture-related risk levels. A comparative analysis was conducted between human observer assessments and machine-derived data to unveil the camera's viewpoint influence on accurate posture classification.
یافتهها
The findings uncovered a notable agreement (Proportion agreement index = 0.89, κ = 0.83) between human observer assessments and machine-derived data, particularly when the subject faced the camera directly. Nevertheless, variations in the camera's viewpoint in relation to the subject's position significantly affected the accuracy of posture classification.
نتیجهگیری
This study showcases promising outcomes in utilizing an RGB camera for posture assessment, emphasizing the significance of machine learning in enhancing ergonomic analysis methodologies. While the results are encouraging, the research highlights the need for further exploration into the practical applications of low-cost RGB cameras in real-world settings. This innovative approach signifies a potential paradigm shift in posture analysis, leveraging machine learning for comprehensive ergonomic assessments.
