Abstract: To provide a three-dimensional survey apparatus, a three-dimensional survey method, and a three-dimensional survey program which are capable of suppressing an occurrence of a data-deficient part. A three-dimensional survey apparatus includes a collimating ranging unit, a scanner unit, and a control calculation portion. If there is a data-deficient part where three-dimensional data is not acquired among a measurement object when the scanner unit acquires point cloud data, the control calculation portion executes control to replenish the three-dimensional data related to the data-deficient part having been acquired by the collimating ranging unit to the point cloud data having been acquired by the scanner unit.

Abstract: According to a medical system of an aspect example, an ophthalmic data acquiring unit includes at least one ophthalmic examination apparatus for acquiring ophthalmic data from a patient, and an internal medicine data acquiring unit includes at least one internal medicine examination apparatus for acquiring internal medicine data from the patient. An inference processor is configured to perform inference processing using a trained model constructed by machine learning using training data that includes ophthalmic data, internal medicine data, and diagnostic result data. The inference processor generates inferred diagnostic data by performing the inference processing based at least on the ophthalmic data of the patient acquired by the ophthalmic data acquiring unit and the internal medicine data of the patient acquired by the internal medicine data acquiring unit. An output unit outputs a result of the inference processing performed by the inference processor.

Abstract: A surveying method using a surveying system including a surveying device and a terminal. The surveying method includes: receiving, by the terminal, a result of selecting a survey target foundation point from among a plurality of consecutive foundation points; obtaining an intersection between a reference line and a boundary side set in advance, the reference line connecting the survey target foundation point and an adjacent foundation point adjacent to the survey target foundation point; and outputting, in association with the survey target foundation point, a relative positional relationship between the intersection and a survey target device surveyed by the surveying device for the survey target foundation point.

Abstract: A scanning apparatus includes a scanner configured to move a scanning spot along a movement path to capture three-dimensional information of a target object. The movement path includes a plurality of b-scan paths performed along a c-scan path. The scanning apparatus also includes a processing circuit configured as a controller to control the movement path of the scanning spot. An area of the target object covered by the movement path may be independent of a length of the b-scan path. The processing circuit may be configured as an analyzer configured to determine a saturation time for each three-dimensional position within a portion of the target object based on an inter-scan time.

Abstract: An ophthalmic apparatus includes an interference optical system, an optical scanner controller, and a correction controller. The interference optical system includes an astigmatism correction optical member and an optical scanner, and is configured to split light from a light source into reference light and measurement light, to irradiate the measurement light onto the subject’s eye via the astigmatism correction optical member and the optical scanner, and to detect interference light between returning light of the measurement light from the subject’s eye and the reference light. The optical scanner controller is configured to control the optical scanner so as to deflect the measurement light in a horizontal direction and a vertical direction on a plane perpendicular to an optical axis of the interference optical system. The correction controller is configured to control the astigmatism correction optical member so as to correct astigmatism based on a detection result of the interference light obtained by the interference optical system.

Abstract: A target device, which allows a sufficient amount of reflected light to be obtained from an end portion, is provided and includes a measurement section. In the target device, a retroreflective layer in which a plurality of retroreflective elements are arranged on the entire circumference in a circumferential direction about an axis is formed on at least part of the outer peripheral surface of the measurement section. The retroreflective layer is formed into an uneven shape in which a distance from the axis changes along the entire circumference in the circumferential direction.

Abstract: A survey system is provided which includes a surveying instrument capable of performing distance and angle measurements of a target attached to a pole, a controller as a glove-shaped wearable device to be worn on a hand of a worker, and configured to transmit commands to the surveying instrument from an input unit for inputting commands, and an eyewear device capable of performing display superimposed on a landscape. Measurement points are displayed by being synchronized with and superimposed on a landscape of a survey site on the eyewear device, and by inputting a command by a worker from the glove-shaped controller that the worker wears into the surveying instrument while the worker grips the pole, distance and angle measurements of the target are made. Unnecessary turning of gaze and hand movements are omitted, and a survey work can be efficiently performed by the worker alone.
