This research develops a new system model, which automatically analyzes and accumulates a construction work crew′s productivity data using image processing technologies.

New algorithms are proposed for each module. YCbCr settings are used to develop a calibration algorithm for improving the rate of recognition. Work sampling and video editing are used to develop an algorithm for measuring and analyzing the crew′s productivity data.
