Abstract: Versatile and convenient safety management of a construction machine is achieved. Construction machines and workers are photographed by a camera of a surveying apparatus. The images of a construction machine and a worker are identified in the photographic image. The positions of the construction machine and the worker that are identified in the photographic image are measured by the surveying apparatus with the use of laser light. The separation distance between the construction machine and the worker in which the positions are measured is calculated. In the case in which the calculated separation distance is at a threshold or less, a warning is issued to the construction machines and the workers.

Abstract: Correspondence relationships between two laser scanning point clouds are easily determined with high accuracy. A data processor includes a laser scanning point cloud acquiring unit and a laser scanning point cloud correspondence relationship determining unit. The laser scanning point cloud acquiring unit acquires a first laser scanning point cloud that is obtained in a first time period and a second laser scanning point cloud that is obtained in a second time period. The laser scanning point cloud correspondence relationship determining unit determines correspondence relationships between the first laser scanning point cloud and the second laser scanning point cloud on the basis of a laser scanning point cloud relating to a fixed object. The fixed object is contained in both the first laser scanning point cloud and the second laser scanning point cloud and does not change between the first time period and the second time period.

Abstract: In the ophthalmic apparatus 1 of an aspect example, the image acquiring unit (the fundus camera unit 2, the OCT unit 100, the image data constructing unit 220) acquires an anterior segment image constructed based on data collected from an anterior segment of a subject's eye by OCT scanning. The part image identifying processor 231 performs identification of two or more part images respectively corresponding to two or more parts of the anterior segment from the anterior segment image acquired. The part image assessing processor 232 performs image quality assessment of each of the two or more part images. The anterior segment image assessing processor 233 performs image quality assessment of the anterior segment image based on two or more pieces of assessment data respectively obtained for the two or more part images.

Abstract: A non-destructive inspection system 1 includes a neutron detecting unit 4 and an arithmetic unit 60. The neutron detecting unit 4 includes a collimator 30 and a neutron detector 20 integrated together. The collimator 30 has a wall defining a through passage P. The wall is made from a material that absorbs neutrons produced via an inspection object. The neutron detector 20 is capable of detecting neutrons that have passed through the collimator 30. The arithmetic unit 60 generates information on a position and composition of the inspection object, based on information on the neutrons detected by the neutron detector 20, positional information indicating the position of the neutron detecting unit 4, and posture information indicating the posture of the neutron detecting unit 4. The positional information and the posture information are detected by a position and posture detecting unit 5.

Abstract: A new technique is provided to easily grasp the form of the fundus and the like of the eye to be examined being depicted in a tomographic image. An ophthalmic information processing device includes an image rotation circuit and a display control circuit. The image rotation circuit rotates a tomographic image of the eye to be examined acquired by using optical coherence tomography while making a measurement optical axis be eccentric relative to a predetermined site of the eye to be examined, in accordance with an eccentric amount and an eccentric direction of the measurement optical axis relative to the predetermined site. The display control circuit causes a display device to display the tomographic image rotated by the image rotation circuit.
