Document Type and Number:
Japanese Patent JP7219192
Kind Code:
B2
Abstract:
To provide a deterioration state diagnosis method capable of efficiently diagnosing a deterioration state of a structure by an image recognition technique using artificial intelligence and avoiding an erroneous diagnosis.SOLUTION: A diagnosis method that diagnoses a deterioration state of a structure 20 from detection results by an image analysis program and an artificial intelligence using a high-pixel image, includes: an image acquisition step S1 of acquiring a high pixel image of the structure 20; an image pixel reduction step S2 of reducing the number of pixels in the high pixel image; a part identification step S3 of specifying a prescribed part and type of the structure 20 in the pixel reduced image by artificial intelligence; and a part specific damage detection step S4 of inputting an ultra high pixel image of the prescribed part and type specified in the part identification step S3 to a deterioration detection model that has been trained in regards to the damage state, and outputting the damage state of the structure by artificial intelligence. A diagnostician diagnoses the deterioration state of the structure 20 from the displayed damage state.SELECTED DRAWING: Figure 3
