Estimation method, control method and control device

A control device for an imaging system to irradiate a base material with laser, comprising:

• an estimation part that inputs temperature distribution data representing a temperature distribution at said imaging system to a learned model and acquires an estimated exposure result that is an estimation of an exposure result output from said learned model;
• a distortion amount calculation part that calculates a distortion amount of a laser irradiation position from said estimated exposure result;
• an exposure pattern compensation part that generates a compensated exposure pattern by compensating for a laser irradiation position in an exposure pattern on the basis of the calculated distortion amount;
• and
• an imaging implementation part that irradiates said base material with laser on the basis of said compensated exposure pattern.
