PROBLEM TO BE SOLVED: To improve the stability of the estimation of a camera attitude while suppressing the increase of a calculation load and the increase of a database.SOLUTION: A camera attitude estimation device 1 for estimating the camera attitude of an imaging device which photographs an object includes: a feature point detection part 11; a matching part 12; and a camera attitude calculation part 13. The feature point detection part 11 detects the feature point of the object, and the camera attitude calculation part 13 calculates the relative attitude of the imaging device to the object. The matching part 12 selects a candidate which can be a corresponding point on the basis of the coordinates of the candidate and the position of the imaging device in the case of photographing an input image in which the feature point corresponding to the candidate has been detected, and determines a corresponding point associated with the feature point from among the candidates by using a local featured value corresponding to the feature point detected by feature point detection means.
