SYSTEM AND METHOD FOR VISUAL INSPECTION AND 3D WHITE LIGHT SCANNING OF OFF-LINE INDUSTRIAL GAS TURBINES AND OTHER POWER GENERATION MACHINERY

摘要

Internal components of gas or steam turbines are inspected with a 3D scanning camera inspection system that is inserted and positioned within the turbine, for example through a gas turbine combustor nozzle port. Three dimensional internal component measurements are performed using projected light patterns generated by a stripe projector and a 3D white light matrix camera. Real time dimensional information is gathered without physical contact, which is helpful for extracting off-line engineering information about the scanned structures. Exemplary 3D scans, preferably with additional visual images, are performed of the gas path side of a gas turbine combustor support housing, combustor basket and transition with or without human intervention.
