Automatic Construction Site Management with Aerial and Close Range Photogrammetry

Aerial photos and engineering blueprints developed in a related database can be used for facilitating construction site management by their distinct contrast features. The contrast would be much more distinguishing through the 3D spatial factors. The 3D spatial factors are mostly from the aerial photos and close range image by means of image processing and feature extraction. Geography Information System (GIS) deployed on ArcView serves as an interfacing port between user and database for information inquiry and analysis. All the spatial data are constructed into as multi-layered vector structure. Main tasks of the interface are the extraction of multi-dimension temporal and spatial features, and their corresponding factors that can be used to verify the actual construction progress on site.
