Abstract: A moving object movement system includes a moving object that moves in accordance with any one method of autonomous movement or remote controlled movement, a control server that is connected to the moving object via wireless communication, and a traveling path deciding unit that calculates an unable-to-move risk indicating a possibility that movement is unable to be performed in accordance with any one method of the autonomous movement or the remote controlled movement on the basis of map information including movement paths of the moving object, autonomous movement difficulty level information indicating a difficulty level of the autonomous movement by the moving object, and communication quality information indicating a communication quality necessary for the moving object to perform the remote controlled movement, and decides a movement path in which the calculated unable-to-move risk is smallest among the movement paths.
Abstract: An image generating apparatus is provided with: first and second light sources that illuminate a material; an image sensor on which the material is disposed; a mask which includes a light-transmitting part that transmits light and a light-blocking part that blocks light, and which is positioned between the image sensor and the first and second light sources; and a light and dark image processing unit. The image sensor acquires first and second images of the material when illuminated by the first and second light sources, respectively. The light and dark image processing unit derives a difference between a luminance value of a pixel included in the first image and a luminance value of a pixel included in the second image at the same position as the pixel included in the first image, and thereby generates a third image of the material.
Abstract: An endoscope system of the present invention includes: a first illumination unit that emits first illumination light for imaging two sets of image information about a subject at different depths; a second illumination unit that emits second illumination light having a wide band covering a visible band from a position different from the position of the first illumination light; an imaging unit that images a first illumination image and a second illumination image of the subject that is illuminated with the first illumination light and the second illumination light; a separation processing unit that separates the two sets of image information from the first illumination image; and a separated-image generating unit that generates two separated images by processing the second illumination image using the two sets of image information.

Abstract: An endoscope system according to the present invention includes: an illumination unit that radiates illumination light onto a subject, the illumination light having a spatially non-uniform intensity distribution including a light section and a dark section in a beam cross section orthogonal to an optical axis; an imaging unit that images an illumination image of the subject irradiated with the illumination light; and a separation processor that generates two separate images from the illumination image. Among intensity values of pixels within the illumination image respectively corresponding to the light section, the dark section, and a section having intermediate intensity between the light section and the dark section, the separation processor generates the two separate images based on at least two of the intensity values.

The ferritic stainless steel includes a microstructure that includes a ferrite phase as a main phase and a crystallized carbide, an area fraction of a Nb carbide, a Ti carbide, a V carbide, a Ta carbide, and a composite carbide thereof to the crystallized carbide of 30% or more. The component contains 50% by mass or more of Al.
Abstract: A monitoring system includes a monitoring control device, an image information providing device, and a client control device. The monitoring control device monitors infrastructure facilities and transmits statuses of the infrastructure facilities acquired on the basis of information input from a sensor to the image information providing device. The image information providing device generates original image information on the basis of the infrastructure facility statuses received from the monitoring control device. The client control device is connected to a display device and an operation device, receives information for designating a partial area of an entire image capable of being generated from the original image information from the operation device, transmits the received information to the image information providing device, and displays an image based on information received from the image information providing device on the display device.
