Abstract: A data processing apparatus (100) includes a target object position determination unit (103) that determines, based on a picture image acquired by a first camera, a position of a target object in the picture image, a target object depth distance extraction unit (104) that extracts the depth distance from the first camera to the target object, a coordinate transformation unit (105) that transforms the position of the target object in the picture image into a position of the target object in a world coordinate system by using the depth distance, and a label transformation unit (106) that transforms, by using a position of the first camera in the world coordinate system and imaging information used when an image is generated from a measurement result of a sensor, the position of the target object in the world coordinate system into a label of the target object in the image.

Abstract: 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.

Abstract: A image processing apparatus (20) includes at least an acquisition unit (210), a processing unit (220), and an image generation unit (230). The acquisition unit (210) acquires an intermediate frequency signal from an irradiation apparatus (10). The processing unit (220) generates three-dimensional positional information about a subject by processing the intermediate frequency signal. The image generation unit (230) generates at least a first two-dimensional image and a second two-dimensional image, and displays the two-dimensional images on a display apparatus (30). The first two-dimensional image is, for example, an image when viewed from a direction in which the subject moves, and the second two-dimensional image is, for example, an image when viewed from an opposite direction.

Abstract: A mapping system includes a non-transitory computer readable medium configured to store instructions. The mapping system includes a processor connected to the non-transitory computer readable medium. The processor is configured to execute the instructions for receiving an input signal including image data of a scene; and determining a position of a sensor used to capture the image data relative to a reference map of the scene. The processor is configured to execute the instructions for determining a change point and a change score in the scene based on the determined position of the sensor and the reference map; and generating a change map based on the change point and the change score. The processor is configured to execute the instructions for generating an update map based on a comparison between the change map and the reference map; and maintaining a content of the reference map unchanged.

Abstract: A target object detection apparatus (20) includes an acquisition unit (210), a likelihood information generation unit (220), and a determination unit (230). The acquisition unit (210) acquires an IF signal from an irradiation apparatus (10) at a plurality of timings. The likelihood information generation unit (220) executes, by processing the IF signal, processing of generating, with respect to each of a plurality of IF signals, likelihood information for a region (hereinafter, referred to as a target object region) having a possibility in that an accompaniment, i.e., a target object is present. The likelihood information indicates a distribution of presence probabilities of a target object in at least a height direction in a target object region. Then, the determination unit (230) determines a presence or absence of a target object, by using likelihood information generated for each of a plurality of target object regions.

Abstract: A receiver receives a radio wave transmitted to a target and scattered by the target to acquire a signal. An imaging unit generates a 3D complex image of the target based on the signal. A value extraction unit extracts intensity information and phase in including an intensity matrix and a phase matrix, the extracted intensity information constituting the intensity matrix and the extracted phases information constituting the phase matrix. A subset selection unit selects a subset from the value set. A transformation unit changes a representation of the subset to generate a 2D real image. A detection unit detects whether there is an undesired object on the target based on the 2D real image.
