Document Type and Number:
Japanese Patent JP7356942
Kind Code:
B2
Abstract:
To specify a damage in a sewer accurately.SOLUTION: A sewer damage specification device includes: an image acquisition unit for acquiring a first inner surface image as an image of an inner surface of a first sewer; a first flat surface image generation unit for generating a plurality of first flat surface images obtained by cutting the first inner surface image open at an arbitrary position of the first sewer in the first inner surface image and developing the image; a damage determination unit for determining a damage which is occurring in the first sewer by using the plurality of first flat surface images; a model generation unit for generating a learned damage specification model by providing an identifier which can identify the determined damage and causing an artificial intelligence to learn the determined first damage and the first flat surface image; an image reception unit for receiving a second inner surface image of an inner surface of a second sewer; a second flat surface image generation unit for generating a plurality of second flat surface images obtained by cutting the second inner surface image open at an arbitrary position of a second sewer in the second inner surface image and developing the image; and a damage determination unit for determining a damage which is occurring in the second sewer by using the second flat surface image and the learned damage specification model.SELECTED DRAWING: Figure 2
