Part of: Construction Research Congress 2010: Innovation for Reshaping Construction Practice
Abstract: A contractor usually employs observers or employees to collect information from construction sites to verify the progress. The accuracy level of these field data significantly decreases because of the human errors and limitations in data availability. This paper describes a novel conceptual model called "Automated Multiple Objects Tracking System (AMOTS)" using latest technologies such as audio and video surveillance. The system tracks objects (workers, tools, etc.) based on the characteristics of the objects (unique shape of the objects and the unique sound patterns of the tools). A well-known correlation method and image subtraction method are applied to detect and differentiate the objects of the site. AMOTS also measures the real time work performance of the workers.
