Measurement device and method for controlling measurement device

A method for controlling a measurement device which performs a measurement of a measurement object,

• the measurement device including:
• a distance measuring unit having a light producing element which produces measurement light, a measurement light emitting unit which emits the measurement light, a light receiving unit which receives reflected measurement light, and a light receiving element which receives the reflected measurement light and generates a light reception signal;
• and
• a deflecting unit which deflects a direction of emission of the measurement light with respect to a reference optical axis and which is capable of performing a scan with the measurement light with respect to a prescribed center in a circumferential direction,
• the method comprising:
• a distance measurement step of performing a distance measurement of the measurement object on the basis of a light reception signal from the light receiving element;
• an intersection point detection step of detecting coordinates of intersection points of the measurement object that is formed in a linear shape and a scan trajectory of the measurement light on the basis of a distance measurement result in the distance measurement step and the direction of emission that is deflected by the deflecting unit;
• and
• a control step of controlling a deflection operation of the deflecting unit so that intervals of the intersection points adjacent to each other are constant intervals on the measurement object.
