Abstract: An ophthalmologic information processing apparatus includes an analyzer, a storage unit, and a display controller. The analyzer is configured to specify an atrophy region in a fundus by analyzing data of the fundus of a subject's eye acquired using optical coherence tomography. The storage unit stores image data of the fundus. The display controller is configured to cause a fundus image of the subject's eye to be displayed on a display means based on the image data stored in the storage unit, and to cause a region corresponding to the atrophy region in the fundus image to be displayed on the display means so as to be identifiable.

Abstract: Highly accurate aerial photogrammetry is performed while avoiding increase in cost. A survey data processing device includes an image data receiving part, a location data receiving part, an identification marker detecting part, an identifying part, and a location identifying part. The image data receiving part receives image data of aerial photographs of vehicles. The vehicles are equipped with GNSS location identifying units and identification markers, respectively. The location data receiving part receives location data of the vehicles that are identified by the respective GNSS location identifying units. The identification marker detecting part detects the identification markers of the vehicles from the image data. The identifying part identifies each of the vehicles in the aerial photographs. The location identifying part identifies locations of ground control points (GCPs) in the aerial photographs by using the location data of the vehicles and by using the identification information.

Abstract: An ophthalmological imaging device comprising an objective lens, an interference optical system, an image forming unit, an optical member, and an analyzer. The interference optical system divides light from a light source into measurement light and reference light, causes the measurement light to become incident on a subject's eye via the objective lens, and detects interference light between the reference light and return light of the measurement light that has exited from the subject's eye and passed through the objective lens. The image forming unit forms an image of the subject's eye based on a detection result of the interference light which are acquired by the interference optical system. The analyzer analyzes a first detection result and a second detection result of the interference light to eliminate noise in the second detection result or in an image based on the second detection result.

Abstract: Ophthalmological mages generated by coherent imaging modalities have multiple types of noise, including random noise caused by the imaging system and speckle noise caused by turbid objects such as living tissues. These noises can occur at different levels in different locations. A noise-reduction method and system of the present disclosure thus relates to applying different filters for different types of noise and/or different locations of images, sequentially or in parallel and combined, to produce a final noise-reduced image.

Abstract: Systems and methods are described for colorizing a point cloud comprising a set of point cloud data points associated with a particular object using a plurality of candidate images. For each respective data point in the set of point cloud data points, an image is selected, from a subset of the plurality of candidate images that include an un-occluded point of the particular object corresponding to the respective data point, that has a shortest subject distance to the un-occluded point of the particular object. The respective data point is colorized based on a color in the selected image of the un-occluded point of the particular object corresponding to the respective data point.

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.
