Aircraft-utilizing deterioration diagnosis system

Abstract

The present invention relates to an aircraft-utilizing deterioration diagnostic system and provides a technique capable of improving diagnostic efficiency and accuracy when comparing the previous and current aerially-photographed images to diagnose a deteriorated state of a target. The diagnostic system includes: a drone(aircraft) configured to be navigated along a route around a targetand having a cameraconfigured to photograph the target; and a computer (PCand server) configured to control navigation of the aircraft and photographing by the camera. The computer is configured to: acquire data from the aircraft including an image group obtained by consecutively photographing the targetfor each predetermined date and time; based on diagnostic data including a diagnostic image group photographed at a current date and time, reference data including a reference image group of a previous date and time, associate, for the same target, images including the same portion as comparison target images; compare the previous image and the current image among the comparison target images to detect a deteriorate portion; and provide a screen converted and visualized for the user such that the deteriorated portion in the image is plotted on the three-dimensional model of the target.
