摘要：
An angle offset judging device (1) includes: an azimuth histogram generating section (126) for obtaining an appearance frequency of estimated azimuths; and an evaluating section (127) for making an evaluation of whether or not the appearance frequency thus obtained shows a tendency which is observed in a case where an azimuth is properly estimated under a binding condition concerning an advancing direction of a movement of a moving body.
