Abstract:
According to an embodiment, a camera motion estimation device includes a memory and one or more hardware processors configured to function as a first acquisition unit, a second acquisition unit, and an estimation unit. The first acquisition unit is configured to acquire feature point correspondence information indicating correspondence between feature points included in time series images. The second acquisition unit is configured to acquire pixel flow information indicating a locus of a pixel included in the time series image. The estimation unit is configured to estimate a motion of a camera that has captured the time series images, using the pixel flow information and the feature point correspondence information.

Claim (Index 2):
The device according to  claim 1 , wherein\n the one or more processors are further configure function as a determination unit configured to calculate feature point moving vector indicating movement of the feature point from the feature point correspondence information, calculate a pixel moving vector indicating movement of a pixel where the feature point used for calculation of the feature point moving vector is positioned from the pixel flow information, and determine similarity between the feature point moving vector and the pixel moving vector, and wherein the estimation unit estimates the motion of the camera that has captured the time series images, from correspondence of the feature point between the time series images, the feature point having been used for calculation of the feature point moving vector, in a case where the similarity is equal to or larger than a first threshold.
