A measuring unit for reading information from a recording medium on which optical data specific to the optical adaptor is recorded, correcting the optical data on the basis of an error in position of an imaging system in the main endoscope unit, performing coordinate conversion on images used for measurement on the basis of the corrected optical data, and calculating three-dimensional coordinates of any points by matching the two images having undergone coordinate conversion.
