Abstract
The position management device includes: a calculation unit that gives identification on an object being monitored to the object being monitored cyclically imaged, and calculates positional information of the object from an image of the object; a storage unit that associates the identification and an imaging time with the positional information, and stores these items; and a comparison unit that compares, with respect to the object, an absolute value of a difference between the positional information as of a current time and the positional information as of each of the imaging times one and two cycle(s) prior to the current time, as stored in the storage unit, with a predetermined reference value, and outputs the positional information as of the current time if the absolute value for at least one of the imaging times is less than the reference value.
