PROBLEM TO BE SOLVED: To improve the accuracy of positioning.SOLUTION: A detecting portion 11 detects the moving amount of an object positioned within a positioning environment. An obtaining portion 12 obtains an existence probability distribution of the object relative to each absolute position within the positioning environment. An estimating portion 13 estimates a range in which the object is positioned within the positioning environment, by using the moving amount of the object detected by the detecting portion 11 and the existence probability distribution obtained by the obtaining portion 12. A specifying portion 14 specifies a position within the positioning environment in which the object is positioned, on the basis of an estimation result by the estimating portion 13 about the range in which the object is positioned. |
