Structural deterioration determination system for improving the efficiency of utility pole inspection

We introduce a structural deterioration determination system that automatically measures the deflection of concrete utility poles from a 3D model created by using 3D point cloud data. As pole deflection is an accurate precursor of cracking, our automated deflection assessment system improves the efficiency of utility pole inspection, by replacing the conventional visual inspections needed to identify cracking. We show that the time and effort of inspection can be reduced by about 52% compared with conventional visual inspection work.
