Abstract
An inspection support apparatus includes: an image acquisition unit (11) that acquires an image obtained by photographing a concrete structure that is an inspection target; a damage region extraction unit (12) that extracts from the acquired image, a damage region (water leakage, free lime, etc.) appearing on a surface of the concrete structure; a causal part detection unit (17) that detects, in a case where the damage region is extracted, a causal part (a crack, a construction joint, a joint, a peeling part, etc.) causing damage from the image on the basis of a result of extraction of the damage region; and an output unit (19) that outputs the result of extraction of the damage region and a result of detection of the causal part.
Claims17
An inspection support apparatus for a concrete structure, the inspection support apparatus comprising a processor configured to:
- acquire an image obtained by photographing a concrete structure that is an inspection target;
- extract, from the image, a damage region appearing on a surface of the concrete structure;
- detect, in a case where the damage region is extracted, a causal part causing damage from the image on the basis of a result of extraction of the damage region;
- output the result of extraction of the damage region and a result of detection of the causal part;
- acquire information about a damaged surface from which the damage region is extracted;
- detect the causal part from the image on the basis of the result of extraction of the damage region and the information about the damaged surface;
- acquire as the information about the damaged surface, information about a direction of gravity and about an inclination state of the damaged surface relative to the direction of gravity;
- detect the causal part while a central part of the damage region is weighted in a case where an inclination of the damaged surface is greater than or equal to a threshold value;
- and
- detect the causal part while a part on an upper side of the damage region in direction of gravity is weighted in a case where the inclination of the damaged surface is less than the threshold value.
An inspection support method for a concrete structure, the inspection support method comprising:
- acquiring an image obtained by photographing a concrete structure that is an inspection target;

- outputting the result of extraction of the damage region and a result of detection of the causal part;
- acquiring information about a damaged surface from which the damage region is extracted;
- detecting the causal part from the image on the basis of the result of extraction of the damage region and the information about the damaged surface;
- acquiring as the information about the damaged surface, information about a direction of gravity and about an inclination state of the damaged surface relative to the direction of gravity;
- detecting the causal part while a central part of the damage region is weighted in a case where an inclination of the damaged surface is greater than or equal to a threshold value;
- and
- detecting the causal part while a part on an upper side of the damage region in direction of gravity is weighted in a case where the inclination of the damaged surface is less than the threshold value.
