Abstract
A moving state estimating device () includes a feature point candidate extracting part () configured to extract feature point candidates in an image taken at a first time point by an imaging sensor () mounted on a vehicle, a positional relation obtaining part () configured to obtain a positional relation of an actual position of each feature point candidate relative to the vehicle, a feature point selecting part () configured to select a feature point candidate as a feature point based on the positional relation of the feature point candidate, a corresponding point extracting part () configured to extract a corresponding point in an image taken by the imaging sensor () at a second time point corresponding to the selected feature point, and a moving state estimating part configured to estimate a moving state of the vehicle from the first time point to the second time point based on a coordinate of the selected feature point and a coordinate of the corresponding point.
