Abstract: A displacement detecting apparatus according to the invention comprises: a mover which moves and positions a positioning object; an imager which images an image including an imaging object which is the positioning object or an object displacing integrally with the positioning object as the positioning object is displaced; and a displacement detector which detects the imaging object from the image imaged by the imager and detects a displacement of the positioning object based on the position of the imaging object detected in the image, wherein the displacement detector obtains a displacement amount of the positioning object with respect to a predetermined reference position from a value obtained by multiplying a distance between the position of the imaging object and the reference position in the image by a coefficient determined according to size of the imaging object in the image.

Abstract: This invention is to provide a technique capable of detecting a displacement of a positioning object with respect to a reference position in an actual space with high accuracy. A position of an imaging object detected in an imaged image is converted into a displacement of the positioning object with respect to the reference position in the actual space based on conversion information representing a correlative relationship between the position of the imaging object in the image and the displacement of the positioning object from the reference position. The conversion information is determined in advance based on positions of the imaging object detected from a plurality of images respectively imaged with the positioning object positioned at each of a plurality of imaging positions.
