摘要:
To enable stable collision avoidance operation without the need to install an infrastructure or the like even in a dangerous area where running out is likely to occur. An autonomous moving body according to the present invention includes: a distance measuring sensor that measures a distance to an object existing in an environment; a distance information acquisition unit that acquires a distance measurement value of the distance measuring sensor as distance information on a measurement point; and a dangerous area extraction unit that categorizes adjacent measurement points as an identical object according to a distance difference between the measurement points, and extracts an endpoint of the object as a dangerous area when the categorized object itself has a size equal to or larger than a predetermined threshold and when an opening formed between endpoints of the objects has a width equal to or larger than a predetermined threshold, in which the autonomous moving body travels so as to avoid a collision in the extracted dangerous area.

An X-ray imaging apparatus includes a multi X-ray source which includes a plurality of X-ray focuses to generate X-rays by irradiating X-ray targets with electron beams, a detector which detects X-rays which have been emitted from the multi X-ray source and have reached a detection surface, and a moving mechanism for moving the multi X-ray source within a plane facing the detection surface. The X-ray imaging apparatus acquires a plurality of X-ray detection signals from the detector by causing the multi X-ray source to perform X-ray irradiation while shifting the positions of a plurality of X-ray focuses which the detector has relative to the detection surface by moving the multi X-ray source using the moving mechanism. The apparatus then generates an X-ray projection image based on the plurality of X-ray detection signals acquired by the detector.
