Measurement device, method of operating measurement device, and recording medium

A method of operating a measurement device, comprising:

• an image acquisition step in which an image acquisition unit acquires a first image of a subject;
• a display step in which a display control unit causes a monitor to display at least one of the first image and a second image based on the first image;
• an information reading step in which an information reading unit reads out measurement mode information indicating a measurement mode from a recording medium having the measurement mode information recorded therein;
• a reference designation point setting step in which a reference designation point setting unit sets a plurality of reference designation points in one of the first image and the second image displayed on the monitor, on the basis of a first position designated by a user in one of the first image and the second image displayed on the monitor;
• a first reference calculation step in which a reference calculation unit calculates one of a reference line and a reference plane on the basis of the plurality of reference designation points, the reference line and the reference plane being used in the measurement mode indicated by the measurement mode information;
• a measurement point setting step in which a measurement point setting unit sets a measurement point in one of the first image and the second image displayed on the monitor, on the basis of a second position designated by the user in one of the first image and the second image displayed on the monitor;
• a reference point calculation step in which a reference point calculation unit calculates a plurality of reference points leading to higher reliability of a measurement result instead of the plurality of reference designation points, on the basis of one of the first image and the second image in which the measurement point is set, the plurality of reference designation points, the measurement mode, and the measurement point;
• a second reference calculation step in which the reference calculation unit calculates one of a new reference line and a new reference plane on the basis of the plurality of reference points;
• and
• a measurement step in which a measurement unit executes measurement of the subject on the basis of one of the new reference line and the new reference plane, the measurement point, and the measurement mode;

A computer-readable non-transitory recording medium having a program recorded therein, the program causing a computer to execute:

• an image acquisition step of acquiring a first image of a subject;
• a display step of causing a monitor to display at least one of the first image and a second image based on the first image;
• an information reading step of reading out measurement mode information indicating a measurement mode from a recording medium having the measurement mode information recorded therein;
• a reference designation point setting step of setting a plurality of reference designation points in one of the first image and the second image displayed on the monitor, on the basis of a first position designated by a user in one of the first image and the second image displayed on the monitor;
• a first reference calculation step of calculating one of a reference line and a reference plane on the basis of the plurality of reference designation points, the reference line and the reference plane being used in the measurement mode indicated by the measurement mode information;
• a measurement point setting step of setting a measurement point in one of the first image and the second image displayed on the monitor, on the basis of a second position designated by the user in one of the first image and the second image displayed on the monitor;
• a reference point calculation step of calculating a plurality of reference points leading to higher reliability of a measurement result instead of the plurality of reference designation points, on the basis of one of the first image and the second image in which the measurement point is set, the plurality of reference designation points, the measurement mode, and the measurement point;
• a second reference calculation step of calculating one of a new reference line and a new reference plane on the basis of the plurality of reference points;
• and
• a measurement step of executing measurement of the subject on the basis of one of the new reference line and the new reference plane, the measurement point, and the measurement mode.
