Abstract
A crack analysis device includes a captured image acquiring unit, a crack detecting unit, and a crack ratio calculator. The captured image acquiring unit acquires a captured image which is obtained by imaging a road surface. The crack detecting unit detects cracks in the imaged road surface on the basis of the captured image. The crack ratio calculator calculates a crack ratio indicating a ratio of an area of the cracks to a predetermined area on the basis of the detected cracks.
Claims25
A crack analysis device comprising:
- a captured image acquiring unit configured to acquire a captured image which is obtained by imaging a road surface;
- a crack detecting unit configured to detect cracks of the imaged road surface on the basis of the captured image;
- and
- a crack ratio calculator configured to calculate a crack ratio indicating a ratio of an area of the cracks to a predetermined area on the basis of the detected cracks, wherein the crack ratio calculator calculates the crack ratio for each of sections into which a road surface is divided with a predetermined area and generates display data in which display is changed for each section on the basis of the calculated crack ratio.
A crack analysis method comprising:
- a captured image acquiring step of acquiring a captured image which is obtained by imaging a road surface;
- a crack detecting step of detecting cracks of the imaged road surface on the basis of the captured image;
- and
- a crack ratio calculating step of calculating a crack ratio indicating a ratio of an area of the cracks to a predetermined area on the basis of the detected cracks, wherein the crack ratio calculating step includes calculating the crack ratio for each of sections into which a road surface is divided with a predetermined area and generating display data in which display is changed for each section on the basis of the calculated crack ratio.
A non-transitory computer readable storage medium that stores a computer program to be executed by the computer to perform:
- a captured image acquiring process of acquiring a captured image which is obtained by imaging a road surface;
- a crack detecting process of detecting cracks of the imaged road surface on the basis of the captured image;
- and
- a crack ratio calculating process of calculating a crack ratio indicating a ratio of an area of the cracks to a predetermined area on the basis of the detected cracks, wherein the crack ratio calculating process includes calculating the crack ratio for each of sections into which a road surface is divided with a predetermined area and generating display data in which display is changed for each section on the basis of the calculated crack ratio.
