Description
Summary:This research study employs the use of a quadrotor for improving the efficiency and safety of civil engineers in the inspection of concrete bridge building columns for probable cracks. At an initial scanning height, the quadrotor hovers vertically at constant height increments and captures the structure image. It communicates, via Wi-Fi, to an android device running the rapid screening algorithm for crack detection. Out of 23 collected images from a bridge structure, the average accuracy achieved was 95.65% with a precision of 91.67% and a recall of 83.33%. © 2016 IEEE.
