摘要：

An image processing device (10) according to the present disclosure comprises: a skeleton detection unit (11) which detects two-dimensional skeleton structures of a plurality of persons on the basis of an acquired two-dimensional image; a feature value computation unit (12) which computes feature values of the plurality of two-dimensional skeleton structures detected by the skeleton detection unit (11); and a recognition unit (13) which carries out a recognition process of the state of the plurality of persons on the basis of the similarity of the plurality of feature values computed by the feature value computation unit (12).
