PROBLEM TO BE SOLVED: To provide an inner surface inspection device capable of determining whether or not an imaging unit is in a state capable of being inserted into an object.SOLUTION: An abnormality determination section 40 obtains an amount of deviation of the central axis of the inner space of an object from a reference axis of an imaging unit in an obtained whole image obtained by imaging an optically cut section of the inner surface of the object with an imaging section 20 facing the entrance of the inner space of each object tube 100, on the basis of a coordinate deviation between imaging center coordinates that are the center of the obtained whole image and object center coordinates that are the center of an optically cut section image appearing in the obtained whole image, and determines whether or not there is abnormality on the basis of the amount of deviation of the axis. |
