Abstract: An object of the present invention is to provide a compact and highly-accurate three-dimensional shape measurement apparatus. The three-dimensional shape measurement apparatus according to the present invention causes a part of a measurement light to proceed in a direction which is different from a direction with respect to a subject as an angle measurement light, and detects a rotation angle using the angle measurement light.

Abstract: The problem to be solved by the invention is to accurately detect a distant object while preventing an increase in cost. An object recognition device includes: an imaging unit configured to acquire a plurality of thermal images having an object captured therein; a stereo matching unit configured to perform stereo matching using the plurality of thermal images and calculate a distance to the object; a specific temperature region extracting unit configured to extract a specific temperature region from the thermal images; and an area ratio estimating unit configured to estimate, based on the distance to the object calculated by the stereo matching unit, a ratio of an area of the object included in a pixel for the specific temperature region.

Abstract: When a part already transmitted to an object storage is updated by a file system management section while a plurality of parts are being transmitted to the object storage, a file transfer section requests the object storage to generate a temporary object that is a temporarily generated object containing the transmitted and updated part by combining the parts transmitted before update, re-splits a file into a plurality of parts so that the transmitted and updated data and not-transmitted data are handled as parts different from transmitted and not-updated data, and transmits the part containing the transmitted and updated data or the part containing the not-transmitted data to the object storage.
