<p>In electronic distance measurement, light emitted from a light source (6) is radiated toward a subject to be measured (2), reflected light reflected by the subject to be measured is received by a light receiving section (8), the light emitted from the light source is received as internal light through an internal light path (11) by the light receiving section, and based on the light reception results of the reflected light and the internal light received by the light receiving section, the distance to the subject to be measured is measured. Correction information is acquired based on the internal light, the acquired correction information is stored, a correction value is acquired from the correction information based on the reflected light and the internal light, and the distance is calculated using the correction value and the light reception results of the reflected light and the internal light received by the light receiving section.</p> |
