1998 IEEE Workshop on Emerging Technologies Intelligent Measurement and Virtual Systems for Instrumentation and Measurement ETIMVIS 98 St Paul MN USA May 15 16 1998 Remote Enhanced Visual Inspection of Aircraft by a Mobile Robot Mel Siegel and Priyan Gunatilake The Robotics Institute School of Computer Science Carnegie Mellon University Pittsburgh PA 15213 USA phone 412 268 8802 fax 412 268 5569 email mws cmu edu Aircraft skin inspection methodology and the technical and economic advantages that can be expected from doing it with the aid of robotics automation and computer vision technologies are reviewed Robots for deployment of inspection systems are described briefly Computer vision methods and algorithms for detection of cracks surface corrosion and subsurface corrosion are then discussed in detail Cracks and surface corrosion are both detected by algorithms that pipeline preprocessing enhancement multiresolution wavelet based feature extraction and neural net based feature vector classification subsurface corrosion is detected by a structured laser light surface profiling technique for the pillowing that subsurface corrosion causes Functionality is illustrated by application to current data I Introduction Aircraft skins are regularly inspected both for known classes of problems primarily cracking and corrosion in specific locations known via prior experience and theoretical stress modeling and for random damage as from lightning strikes bumps by ground support vehicles etc Approximately 90 of this inspection is visual the remaining 10 is instrumented primarily using eddy current sensors with ultrasonic and other instruments employed occasionally Robotics and automation technology has potentially large contributions to make in this field the advantages of getting the man off the airplane the tireless concentration of a robot the guarantee of proper and consistent instrument deployment protocol the inherent navigational and record keeping capabilities of a mobile
