INTERFACE SYSTEM FOR CAPTURING WORKERS’ 3D PATHS IN THE CONSTRUCTION PROCESSES

Abstract

Personnel paths of workers are difficult to capture because there are many objects obscure crew from view in construction site. Today, many devises to capture were supplied but they are too big, expensive, or complicated to use in construction site.
In this paper, the author developed interface system for capture personnel paths of crew. It needs only full view movie of area to analyze. Firstly, the system creates time series pictures from video. Secondary, the system calculates 3D coordinates position from two user’s clicks on picture displayed into interface. Lastly, the system saves text data and picture data.
