碩士 === 中原大學 === 機械工程研究所 === 105 === Structure deterioration cause by aging sand plus extreme weather is the one of the major problem in developed country, at same time, aging of society makes the industry automation more important than anything else. State of the art inspection involve human inspector with aerial ladder to perform visual inspection, which is expensive, dangerous and low efficiency. This thesis focuses on providing a safe, fast and more efficient non-destructive infrastructure inspection by using unmanned aerial vehicles. X frame configuration is the most suitable for inspection mission was worked out through flight dynamic mathematical modeling and referencing different on market UAVs. Thus, using in house design fight model to program into modified commercial product to perform actual flight test and mapping mission to prove the flight dynamic modeling. In the later stage with real inspection mission that images captured by normal UAV cannot be used in inspection because each camera has its own lens distortion and orthophoto image cannot be guaranteed, and most importantly, image cannot be quantified, which is essential in engineering, therefore image processing become a must. Secondly, measurement though image means that measure what can be seem, however, image are largely effected by lighting condition, therefore, many damage can be easily skipped if one does not look carefully, thus, image enhancement is also another issue that need to be considered. This thesis also identifies above problems and provides suggestion and research structures for future researchers to complete unmanned system in application for non-destructive testing for infrastructure inspection.
