Repair length determination method and repair length determination apparatus

A repair length determination apparatus comprising:

• an image acquiring unit that acquires an image obtained by imaging a crack repair target region in a structure;
• a crack detecting unit that detects a crack from the image acquired by the image acquiring unit;
• a display control unit that displays the crack detected by the crack detecting unit;
• an operation unit that points a plurality of points including two points at both ends of the crack;
• an interpolation curve creating unit that creates an interpolation curve by using the points pointed by the operation unit;
• and
• a repair length determining unit that detects a length of the interpolation curve and determines a repair length.

A non-transitory, tangible computer-readable medium having stored thereon computer instructions that, when executed by a processor, cause the processor to:

• acquire an image obtained by imaging a crack repair target region in a structure;
• detect a crack from the acquired image;
• control to display the crack on an operating interface;
• receive designation of a plurality of points including two points at both ends of the crack from the operation interface;
• create an interpolation curve by using the plurality of points;
• and
• detect a length of the interpolation curve to determine a repair length.
