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 of a first sewer; a first flat surface image generation unit for generating a first ceiling flat surface image and a first bottom part flat surface image from the first inner surface image; a damage determination unit for determining a damage which is occurring in the first sewer by using the first ceiling flat surface image and the first bottom part flat surface image; a model generation unit for generating a learned damage specification model by causing an artificial intelligence to learn the determined damage and the first ceiling flat surface image and the first bottom part flat surface image; an image reception unit for receiving a second inner surface of a second sewer; a second flat surface image generation unit for generating a second ceiling flat surface image and a second bottom part flat surface image from the second inner surface image; and a damage specification unit for detecting and specifying a damage which is occurring in the second sewer by using the second ceiling flat surface image, the second bottom part flat surface image, and the learned damage specification model, the damage specification unit also specifying a damage by changing a threshold value to detect a damage according to the type of the damage.SELECTED DRAWING: Figure 2
