Abstract: A mobile body (1) includes an image slide unit (11), a parallax histogram aggregation unit (13), and a miscalibration detection unit (14). The image slide unit (11) generates a slide image (SLI) obtained by sliding a first viewpoint image (VPI1) in a parallax direction. The parallax histogram aggregation unit (13) generates a parallax histogram (HG) from the slide image (SLI) and a second viewpoint image (VPI2). The miscalibration detection unit (14) determines that the miscalibration has occurred when a lower boundary value of the parallax on the histogram (HG) is smaller than the slide amount of the first viewpoint image (VPI1).

Abstract: A configuration is described that is capable of determining a target landing position of a drone according to a sentence indicating a landing position generated by a user.

Abstract: An aerial vehicle according to an embodiment of the present technology includes a recording unit, a detection unit, and a reproduction unit. The recording unit records a flight parameter during flight in a state in which no sensor abnormality is detected. The detection unit detects the sensor abnormality. The reproduction unit reproduces the flight parameter on the basis of the sensor abnormality detected by the detection unit.

Abstract: An apparatus for producing and automatically injecting H.sub.2.sup.15 O, having: a target box adapted to be irradiated with a deuteron beam, a gas supplying device for supplying a hydrogen gas and a nitrogen gas as raw-material gases to the target box a radioactive-isotope conveying pipe connecting the target box and a vacuum pump for maintaining the interior of the target box and the interior of the radioactive-isotope conveying pipe in a vacuum state. In addition, the apparatus has an injection-fluid producing device and an automatic injection device, wherein the target box, the injection-fluid producing device and the automatic injection device are fluidly communicated with one another.
