Abstract: Provided is a product detection device capable of detecting a normal product deviated from a normal pattern from normal products determined to be normal. The training means 73 sequentially selects window data and trains a model for restoring latter part data from former part data by using a set of pairs of former part data and latter part data obtained from time series data of each of a plurality of normal products as training data. The difference calculation means 75 calculates a difference between latter part data and restored data for each normal product. The window data decision means 76 decides window data satisfying a predetermined condition based on a difference calculated for each normal product. The product detection means 77 detects a predetermined normal product from a plurality of normal products based on a difference for each normal product obtained based on the decided window data.

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: An information processing apparatus according to the present disclosure includes: at least one memory configured to store instructions; and at least one processor configured to execute the instructions to: generate, for each of a plurality of virtual cameras in a three-dimensional space, a virtual camera image shot by the respective one of the virtual cameras on the basis of point cloud data of the three-dimensional space; and estimate, on the basis of similarity between the virtual camera image generated by having the processor execute the generation instruction and a camera image shot by a camera, location and orientation of the camera when it shot the camera image.
