Worker Positioning Technology for Factory Work Time Measurement

This technical report presents a novel worker positioning technology designed for measuring actual work time in factory environments. The objective is to address productivity bottlenecks caused by variations in production and worker turnover. The developed method utilizes color markers worn by workers, detected through an advanced image processing algorithm, to accurately measure work time. The report outlines the limitations of existing methods, such as direct time study and work sampling, which are time-consuming and inefficient. It details the challenges faced by traditional worker positioning technologies, including wireless radio systems and human recognition AI systems, which often fail to provide the necessary accuracy and ease of implementation. The proposed technology significantly reduces setup time and improves measurement accuracy to less than 0.1 seconds. The report also discusses the verification results from factory implementations, demonstrating the effectiveness of the technology in clarifying productivity issues related to work time dispersion.
