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 such that the measurement light is guided obliquely downward from the light projecting unit to the measuring object, and such that an optical axis of the light receiving unit extends obliquely downward;
• 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 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 point cloud data generated by the point cloud data generating section;
• and
• a first light shielding member that is provided above a space on the stage so as to block ambient light from above the space on the stage, and so as not to block the measurement light, the space being defined on the stage so as to include the measuring object.
