    Abstract: According to an embodiment, an identification device includes a light emission controller, an image capturing controller, a detector, a position calculator, and an identification unit. The light emission controller individually controls lighting on/off of light-emitting instruments via a network. The image capturing controller controls capturing devices by using identification information of the image capturing devices, and obtains an image sequence captured by each image capturing device. The detector detects, for each image sequence, one or more regions varying in conjunction with lighting on/off of the light-emitting instruments. The position calculator calculates, for each image sequence, a position of the image capturing device that captures the image sequence by using a position of the light-emitting instrument performing lighting on/off causing each region.
