Parameter adjustment device, training device, and measurement system

A measurement system comprising:

• a trained model generator to generate a trained model through machine learning using training data sets each including waveform data of an amount of laser light received by a measurement sensor from a training object included in an object and data indicating a parameter relating to control of laser light emitted from the measurement sensor onto the training object to acquire the waveform data;
• a parameter calculator to calculate, by applying waveform data newly acquired in a new state in which the measurement sensor emits laser light onto a measurement object included in the object to the trained model generated by the trained model generator, a parameter for the new state;
• a parameter setter to set the parameter calculated by the parameter calculator to the measurement sensor;
• and
• a measurer to measure the measurement object based on waveform data acquired by the measurement sensor with the parameter set by the parameter setter.
