SPATIALLY INTEGRATED AERIAL PHOTOGRAPHY FOR BRIDGE, STRUCTURE, AND ENVIRONMENTAL MONITORING

摘要

Spatially Integrated Small-Format Aerial Photography (SFAP is one aspect of the present invention. It is a low-cost solution for bridge surface imaging and is proposed as a remote bridge inspection technique to supplement current bridge visual inspection. Providing top-down views, the airplanes flying at about 1000 ft, can allow visualization of sub-inch (large) cracks and joint openings on bridge decks or highway pavements. On board Global Positioning System is used to help geo-reference images collected and allow automated damage detection. A deck condition rating technique based on large crack detection is used to quantify the condition of the existing bridge decks.
