Measuring Device

A measuring device comprising:

• a stage holding unit;
• a stage held by the stage holding unit and on which a measuring object is placed;
• a head unit including a light projecting unit and a light receiving unit, the light projecting unit irradiating the measuring object placed on the stage with measurement light having a pattern, the light receiving unit receiving the measurement light reflected by the measuring object and outputting a light reception signal representing a light reception amount;
• a coupling part that fixedly couples the head unit and the stage holding unit;
• a point cloud data generating section that generates point cloud data representing a three-dimensional shape of the measuring object based on the light reception signal output from the light receiving unit;
• a storage section in which region information is stored, the region information distinguishing a predetermined effective region and an ineffective region other than the effective region from each other with respect to a space on the stage;
• a measurement data obtaining section that performs first obtaining processing, in which the point cloud data corresponding to the effective region is obtained as the measurement data based on the region information stored in the storage section, the point cloud data being generated by the point cloud data generating section;
• and
• a measuring section that receives designation of a point to be measured in the measuring object and calculates a measurement value at the designated point based on the measurement data obtained by the measurement data obtaining section.
