Bridge Inspection using Virtual Realty and Photogrammetry

This paper is divided into three major sections: (1) bridge inspection via virtual realty; (2) bridge monitoring via photogrammetry; and (3) potential impact and future development. The first section briefly covers the current regulations for conducting route bridge inspections. The second section gives an approach using QuickTime Virtual Realty (QTVR), which is described for recording bridge inspection data with a high level of photographic detail. The section covers the basic equipment (hardware and software) and procedures for documenting the physical condition of a bridge using virtual realty techniques. The third section provides a brief overview of photogrammetry including basic definitions, instruments, procedures, and applications. Topics discussed include aerial versus terrestrial photogrammetry; the central perspective projection; measurement by triangulation; photogrammetric camera types, characteristics, and calibration; and photogrammetric analysis fundamentals. The last section of the paper provides some concluding remarks regarding the potential impact of virtual realty and photogrammetry.
