    Abstract: The distance measurement device includes a ToF type distance measurement camera that measures a distance to a measurement object and a distance to a reference object of which the distance is known, and a processor. The processor calculates a correction coefficient on the basis of a first measurement value that is a measurement value of a distance from the distance measurement camera to the reference object obtained by the distance measurement camera and a known distance from the distance measurement camera to the reference object, and corrects a second measurement value that is a measurement value of a distance from the distance measurement camera to the measurement object obtained by the distance measurement camera or a calculation value calculated using the second measurement value.

    Abstract: A setting device comprising: at least one processor, wherein the processor is configured to: acquire imaging part information indicating an imaging part of a subject whose radiographic image is captured by radiation emitted from a radiation emitting device; and derive, in a case in which body thickness information indicating a body thickness of the subject in a direction in which the radiation is transmitted is acquired from a detector that comes into contact with the subject and detects the body thickness, imaging conditions corresponding to the body thickness indicated by the body thickness information and the imaging part indicated by the imaging part information and set the imaging conditions in the radiation emitting device.

    Abstract: A radiation image capturing system capable of improving image quality of a radiation image is provided. A position of a joint of a grid is determined in consideration of displacement of an angle of incidence of radiation on a grid unit and a radiation detector group, and a joint image caused by the joint of the grid is prevented from being included in a search range of a position of a boundary in the radiation image captured by the radiation detector. The joint of the grid is provided in a position away ±(y1+2×y2)×tanβ or more from a position of a step of the radiation detector.

    Abstract: A setting device comprising at least one processor, wherein the processor is configured to: acquire imaging part information indicating an imaging part of a subject captured by a radiation emitting device; acquire body thickness information; derive target values of a tube voltage and a mAs value for emitting the radiation such that a dose of the radiation transmitted through the imaging part is the same as a dose at a reference body thickness, on the basis of the acquired body thickness information and the acquired imaging part information; and derive a set value of a tube current for obtaining the target mAs value and a set value of an irradiation time of the radiation on the basis of at least one of an upper limit value of the irradiation time, a tube current corresponding to a focus size, or a maximum output value of a tube.
