Title:
構造物劣化検出システム
Document Type and Number:
Japanese Patent JP7150468
Kind Code:
B2
Abstract:
To provide a technique capable of shortening a time including a calculation time required for learning and diagnosis in a computer and a user's work time and reducing a user's work load.SOLUTION: A computer system 1 (application 10) of a structure deterioration detection system executes first processing using the deep learning of a first image of a structure 5 as an input to output a second image representing a diagnosis result of deterioration and second processing for visualizing information including a second image to display the visualized information on a GUI screen 21. A CNN consisting of a model 31 of the deep learning includes a widening convolution layer. The first process at a training time inputs a first image patch of a predetermined first input size to the model 31 to obtain a first diagnosis result image of a first output size. The first process at a diagnosis time inputs a second image patch of a second input size to the model 31 from a target image of a variable size to obtain a second diagnosis result image of a second output size.SELECTED DRAWING: Figure 1
