Small format aerial photography (SFAP) with low flying technique is proposed for damage evaluation of bridge decks.
High resolution images obtained using under-belly photography can be used to quantify the various bridge deck
problems. The conventional truck-mount or vehicle-mount deck imaging technologies require a large number of image
samples. Hence the physical scanning is time consuming and it is also challenging consider the size and location of a
bridge. Aerial imaging overcomes these issues, but they face different kinds of challenges that are posed by obstacles
such as shadow from trees, power lines and vehicles, signs and luminaries structures. The image resolution uncertainty,
which is a function of the pilot skills and flying conditions, may also add additional challenges to aerial imaging
technique. Hence different image processing tools have to be integrated into a single package to achieve the desired task.
This paper summarizes the challenges faced and the preliminary results are presented and discussed.
