    摘要: There is provided an object identification apparatus for identifying a stationary object and a moving object. The object identification apparatus includes a phase difference calculator that calculates phase difference information between a transmission signal and a reception signal obtained by reflecting, by surfaces of the moving object and the stationary object in a space, the transmission signal emitted to the space and receiving the reflected transmission signal, a distance calculator that calculates distance information using the phase difference information, a distance information separator that separates the distance information into moving object distance information as distance information about the moving object and stationary object distance information as distance information about the stationary object, and an identifier that identifies the stationary object and the moving object based on the stationary object distance information and the moving object distance information.

    摘要: The present invention provides a processing system (20) including an image capturing unit (21) that captures an image of a person passing through a first area and generates a person image indicating an appearance of the person, an electromagnetic wave transmission/reception unit (22) that emits an electromagnetic wave having a wavelength of 30 micrometers or more and 1 meter or less toward the person passing through the first area, and receives a reflected wave, a determination unit (23) that determines whether the person possesses a pre-designated object, based on a signal of the received reflected wave, and a registration unit (24) that registers, in a first list, the person image of the person determined to possess the pre-designated object.

    摘要: An object is to construct an accurate correspondence relation between points included in 3D data and pixels that form an image. An alignment unit receives image data acquired by capturing an image of an object, and 3D data of the object, performs alignment between the image data and the 3D data, and outputs data after the alignment. A pixel selection unit selects a target pixel from a plurality of pixels included in the image data. The pixel point association unit selects, from a plurality of point data items of 3D data included in the data after the alignment, three or more point data items near the target pixel as neighboring point data, estimates one surface based on the neighboring point data, and performs association for calculating a position of the target pixel on the one surface in a space which the plurality of point data items belong to.
