METHOD FOR CONSTRUCTING INFORMATION SYSTEM FOR ANALYZING DAMAGE INFORMATION ON WATERFRONT STRUCTURE

摘要

The present invention relates to a method for constructing an information system for analyzing damage information on a waterfront structure. An information system for analyzing damage information on a waterfront structure according to the present invention includes a storage part for storing the unmanned aerial images taken at a damage time point and the reference data of the same area constructed in the past; an input part for inputting external facial expression element information of each of the images indicating the position of the image taken and posture information; a confirmation part for confirming an individual photographing position in a footprint form through the external facial expression element from the input unmanned airplane image; and a detection part for detecting three-dimensional point group data by performing image matching from the input unmanned airplane image, comparing the detected three-dimensional point group data with the reference data, and detecting a damage area. It is possible to quickly check a damage situation.;COPYRIGHT KIPO 2017
