The present invention relates to a method for inspecting a damaged state of a structure by processing image information photographed by a drone with an artificial neural network performing deep learning, wherein the drone photographed image information is sequentially processed by a background augur neural network and a damage extraction neural network, type information and actual position information for each group of unit elements are collected, and damage identification information is given to systematically identify a damaged part. According to the present invention, identification information based on actual position information is given to a damaged part on a structure to be inspected, thereby accurately and systematically identifying and classifying individual single damaged parts scattered in a plurality of fragmentary image girders, and image information is processed by sequentially applying two image processing artificial neural networks which are specially learned for background augur and damage extraction and behave independently from each other, thereby improving efficiency and accuracy of damage inspection.
본 발명은 드론에 의하여 촬영된 영상정보를 딥러닝 수행 인공신경망으로 처리하여 구조물의 손상 상태를 점검하는 방법에 관한 것으로, 드론 촬영 영상정보가 배경소거신경망 및 손상추출신경망에 의하여 순차 처리되고, 일군의 단위요소별 종별정보 및 실위치정보가 취합되고 손상식별정보가 부여되어 손상 부위에 대한 체계적인 식별이 가능한 것이다. 본 발명을 통하여, 피검 구조물상 손상 부위에 대하여 실제 위치정보에 기반한 식별정보를 부여함으로써 다수의 단편적 영상장보에 산재된 개별 단일 손상 부위에 대한 정확하고 체계적인 식별 및 분류가 가능하며, 각각 배경소거 및 손상추출에 특화 학습되고 상호 독립적으로 거동하는 2개의 이미지 처리 인공신경망을 순차 적용하여 영상정보를 처리함으로써 손상 점검의 효율성 및 정확성을 향상시킬 수 있다.
