Abstract: An ophthalmologic information processing apparatus includes a reference data setting unit, a first region specifying unit, and a second region specifying unit. The reference data setting unit is configured to set, as first reference data, first fundus data among a plurality of fundus data of a fundus of a subject's eye acquired at different acquisition timings using optical coherence tomography. The first region specifying unit is configured to specify one or more first atrophy regions in the fundus by analyzing the first reference data. The second region specifying unit is configured to specify one or more second atrophy regions by analyzing second fundus data based on the one or more first atrophy regions, the second fundus data being acquired after the acquisition timing of the first reference data among the plurality of fundus data.

Abstract: Provided is an ophthalmic measurement device with which it is possible to obtain an area in which a measurement can be taken without moving an optical system. With reference to an optical path length of an illumination optical system with which light is focused on the eyeground when the refraction value is 0 D, the positions of two light sources are set to achieve a setting in which the optical path length becomes slightly shorter. By doing so, it is possible to cope with measurement of refractive properties in a large area without employing structures that allow a lens system of the illumination optical system and the light sources thereof to be moved. In addition, by selecting one of the two light sources so that a clearer Hartmann image can be obtained, it is possible to further increase the precision of the refractive properties to be measured.

Abstract: A fertilization design device calculates a fertilization amount of a field to be fertilized and includes the following units. A database reception unit receives one or both of growth data indicating growth potential of the field and soil data indicating plant growth potential of soil in the field and receives position data as position coordinate information for the field. A designated position reception and retrieval unit receives a freely selected position designated by a user and retrieves information of the freely selected position from the position data. A user input fertilization amount value reception unit receives a fertilization amount value freely set by the user for the freely selected position or for a range including the freely selected position. A calibration curve generation unit generates a calibration curve, based on one or both of the growth data and the soil data, the position data, and the fertilization amount value.

Abstract: A survey system includes a survey device and a target. The survey device includes a main body rotatable around a vertical axis, a telescope supported by the main body and rotatable around a horizontal axis, a wide angle imaging unit having a second angle of view wider than a first angle of view of the telescope, and a target identification unit configured to identify a target image. The target image is identified based on a differential image between a first image captured by the wide angle imaging unit during an on-period with laser light emitted from an emission unit and a second image captured during an off-period in which laser light is not emitted from the emission unit. The target image is quickly identified even when the target is significantly separated in the horizontal direction from a position directly in front of the survey device.
