Overview: A low cost progress data collection technique was proposed for construction sites using time-lapse video. The authors build on their existing research on 4D CAD and geometric, parameter-based 4D models and apply computer vision techniques to webcam images of construction sites to provide frequent, rapid, and automated feedback on the performance of construction crews with respect to the project schedule. The main steps for this research are camera configuration, camera calibration, segmentation of the images and tracking of the crews and progress of work on components or in areas. As a result of this research, automatic, accurate, and more frequent progress data collection and updating of the schedule and 4D model will be possible.
