Fitting method and repair method

A fitting method for fitting a material to be repaired and a repair patch to be adhesively bonded to the material to be repaired at adhesive surfaces where the material to be repaired and the repair patch are adhesively bonded, each adhesive surface having at least two or more of curved portions, the fitting method comprising:

• measuring a shape of the material to be repaired;
• measuring a shape of the repair patch;
• dividing repair patch shape measurement data acquired at measuring the shape of repair patch into a plurality of pieces of divided data each including one or less of the curved portions;
• performing, at the adhesive surfaces, fitting processing of the pieces of divided data acquired at dividing the repair patch shape measurement data to material-to-be-repaired shape measurement data acquired at measuring the shape of material to be repaired;
• and
• calculating a gap amount between the material-to-be-repaired shape measurement data and repair patch shape fitting data acquired from the fitting processing at the adhesive surfaces.
