Abstract: Generation of an inappropriate image portion in an orthographic image due to occlusion is prevented. An image processing device includes an image data receiving part that receives image data of multiple photographed images taken by photographing an object from different positions, a coordinate designating part that receives designation of a specific position in the object, and an optimum-condition satisfying image selecting part that selects a photographed image that is taken from a direction in a specific range relative to the specific position, from among the multiple photographed images. The selected photographed image is used to obtain pixel information of the specific position.

Abstract: An ophthalmologic apparatus according to the embodiments includes an OCT optical system, an alignment unit, an image forming unit, a first calculator, and a second calculator. The OCT optical system is configured to acquire OCT data of a fundus of a subject's eye by projecting measurement light onto the fundus. The alignment unit is configured to perform alignment of the OCT optical system with reference to a predetermined site of the subject's eye. The image forming unit is configured to form a tomographic image of the fundus based on the OCT data acquired by the OCT optical system which has been aligned by the alignment unit. The first calculator is configured to calculate a first tilt angle of the tomographic image. The second calculator is configured to calculate a second tilt angle of the fundus by correcting the first tilt angle based on alignment result of the OCT optical system with respect to the predetermined site by the alignment unit.

Abstract: An ophthalmologic apparatus includes an OCT measurement unit, a corneal shape measurement unit, an eyeball model generator, and a site specifying unit. The OCT measurement unit is configured to acquire data of a subject's eye by deflecting measurement light using an optical scanner to project onto the subject's eye and detecting interference light between returning light of the measurement light from the subject's eye and reference light. The corneal shape measurement unit is configured to obtain curvature radius distribution on a cornea by detecting returning light of a measurement pattern projected onto a cornea of the subject's eye. The eyeball model generator is configured to generate an eyeball model using the curvature radius distribution on the cornea. The site specifying unit is configured to specify a traveling direction of the measurement light by performing ray tracing on the measurement light incident on each of a plurality of incident positions on the cornea based on a scan angle and the eyeball model, and to specify a position corresponding to an intraocular site of the subject's eye in the traveling direction based on the data acquired using the measurement light.

Abstract: An ophthalmic apparatus of an exemplary aspect performs the first and second OCT scans on a subject's eye. The first OCT scan is performed on the first region including the first site of the subject's eye, and the second OCT scan is performed on the second region including the second site. The ophthalmic apparatus acquires the first deviation information of the subject's eye prior to the first OCT scan and performs alignment, and also acquires the second deviation information of the subject's eye prior to the second OCT scan and performs alignment. The ophthalmic apparatus calculates the distance between the first site and the second site based on the first data acquired through the first OCT scan and second data acquired through the second OCT scan.

Abstract: A mobile body is controlled even in a place in which a navigation signal is difficult to receive from a navigation satellite. A three-dimensional information processing unit operates a device or a functional part which measures three-dimensional coordinates of a controlled target and operates a laser scanner or a laser scanning part which obtains three-dimensional point cloud data of the target. The unit includes a positioning section that operates the device or the functional part which measures the three-dimensional coordinates, to calculate the three-dimensional coordinates, and includes a scan controlling section that obtains the three-dimensional point cloud data from the laser scanner or the laser scanning part. The unit also includes a range calculator that calculates a movable range of the target from the three-dimensional coordinates and the three-dimensional point cloud data, and includes a controlled target position calculator that calculates a position of the target in the movable range.

Abstract: A position guiding device includes a mobile terminal having an imaging part and display, a position information acquiring part for acquiring current coordinate information and target coordinate information, a direction sensor for acquiring direction information, and a controller to generate a target image. The mobile terminal is attached to a pole so as to position a pole tip within an angle of view. The controller acquires, from the position information acquiring part, current coordinate information representing a position at where the pole tip points, defines a horizontal surface including the pole tip as a measurement surface, generates corrected coordinate information by shifting the target coordinate information to a position on the measurement surface, generates the target image in which a target position marker is put at a position representing the corrected coordinate information in the image obtained by the imaging part.

Abstract: A system that includes a clinical database that stores clinical data in association with an internal identifier of a patient. An identifier conversion processor converts internal identifier associated with clinical data to an external identifier. An anonymization processor anonymizes confidential data in clinical data. An anonymized database stores anonymized data including anonymized clinical data and an external identifier associated with the anonymized clinical data. A research database stores anonymized data provided from the anonymized database for individual research projects. A research data provision processor receives a request from a user, reads out from the research database at least part of anonymized data associated with a research project to which the user belongs, and provides it to the user.
