PROBLEM TO BE SOLVED: To improve the estimating accuracy of a camera pause with respect to the subject of a camera.SOLUTION: A camera pause estimation device includes: a three-dimensional coordinate/camera pause acquisition part for tracking a change in feature points in a series of image data, and for acquiring the three-dimensional coordinates of the feature points in a world coordinate system and a camera pause; a template detection part for detecting a region which is similar to a plurality of template images including a part of a subject in the image data; a feature point extraction part for extracting the feature points included in the detected region; a template position estimation part for removing an outlier from among the extracted feature points, and for estimating the three-dimensional position of the template image on the basis of the unremoved feature points; and a camera pause estimation part for estimating a transformation matrix from the world coordinate system to a subject coordinate system with the subject as a reference on the basis of the three-dimensional position estimated by the template position estimation part, and for estimating the camera pause with respect to the subject of the camera which has acquired the image data on the basis of the transformation matrix. |
