PROBLEM TO BE SOLVED: To provide a displacement detection device of a rail that is excellent in maintainability and in which a measurement error does not easily occur.SOLUTION: The displacement detection device includes: a self-position detection part for detecting the relative position and orientation of the device relative to a preset reference position and reference orientation, an irradiation part that irradiates an upper surface and a side surface of a rail with a slit light; an imaging camera that images the surface of the rail irradiated with the slit light from the irradiation part; and a control part that calculates the displacement to the reference position of the rail set beforehand in the upper surface reference point and side surface reference point on the rail from the image data on the surface of the rail imaged by the imaging camera by a light section method, and adjusts the error by the gap of the position and the attitude of the device caused by running of the vehicle by correcting the calculated displacement of the rail by using the data obtained in the self-position detection part. |
