Keywords:crack, UAV, TS tracking system, Diagnostic imaging, Infrared camera

A bridge pier image is taken with UAV and an infrared camera before scaffold assembly about the road viaduct height about 30 m height, deformation inspection such as bridge pier cracks is conducted by image diagnostic method, visual inspection is carried out after scaffold assembly, crack etc. The applicability to the field was evaluated by comparing with the image diagnostic method about the extraction accuracy of. (1) Create highly accurate data by image diagnosis. (2) The crack position is automatically extracted from the image and made into CAD, and further, the form management is automatically created.
