Provided are a new measuring module and a new three-dimensional data measuring system that enable efficient three-dimensional data measurement without a prism equipped pole. The measuring module (50) comprises a prism (51), an electronic distance meter (52), an inertial measurement unit (42), a communication unit (58) and at least one processor (60). The processor (60) is configured to calculate position coordinates of the measuring module based on prism position coordinates, posture information, and to calculate position coordinates of the irradiated point based on the position coordinates of the measuring module, the distance to the irradiated point, and the posture information. The processor (60) is configured to determine that the irradiated point falls within a scheduled-measurement-point range which is defined with a predetermined threshold around a scheduled measurement point, set in a data of the measurement range to measure the irradiated point and record measurement result.

Provided is a three-dimensional data measuring system 1 that enables efficient three-dimensional data measurement without a pole. The system 1 comprises a measuring module 50 including a prism 51, an electronic distance meter 52, an inertial measurement unit 53 configured to detect posture information, a communication unit 58 configured to receive prism position coordinates, and a control arithmetic unit 60 configured to calculate a position of the measuring module 50 based on the prism position coordinates and the posture information to calculate a position coordinates of an irradiated point of the measuring module 50 based on the calculated position of the measuring module 50, a distance to the irradiated point, and the posture information; and a surveying instrument 10 configured to measure a distance to and an angle of the prism 51 to acquire the prism position coordinates and transmit the prism position coordinates to the communication unit 58. When a measurement range exceeds a measurable range where the measuring module 50 performs measurement with a required accuracy without travelling, the system 1 partitions the measurement range into sections in a mesh manner each section having dimensions within the measurement range and sets a measurement route in a guidance data to minimize a travel distance of the measuring module 50, to perform measurement according to the guidance data.

An optical coherence tomography apparatus includes an optical system, a storage unit, and a controller. The optical system is configured to allow an optical condition to be changed, and to acquire optical coherence tomography data of an object to be measured by scanning the object to be measured with measurement light. The storage unit stores in advance setting information for each scan region in the object to be measured, the setting information being information for setting an optical condition of the optical system so that image quality of an image formed based on the optical coherence tomography data becomes equal to or greater than a predetermined image quality level. The controller is configured to change an optical condition of the optical system based on the setting information, and to perform optical coherence tomography on the object to be measured, in accordance with the scan region of the measurement light in the object to be measured.

An ophthalmologic apparatus includes a visual-target presenting portion (41) that is configured to present visual targets (8) to left and right subject eyes (EL, ER), respectively; and an objective measurement optical system (6, 7) that is configured to objectively measure eye characteristics of the left and right subject eyes (EL, ER), respectively. The visual-target presenting portion (41) is configured to present the visual targets (8) while changing a convergence position (R, R1, R2), where two lines of sight (SL1, SR1, SL2, SR2) from positions of the left and right subject eyes (EL, ER) intersect, with pinhole plates (50) respectively disposed at positions conjugate with pupils of the left and right subject eyes (EL, ER). The objective measurement optical system (6, 7) is configured to obtain the objective refractive values of the left and right subject eyes (EL, ER), respectively, under a condition where the pinhole plates (50) are respectively disposed by the visual-target presenting portion (41) and the visual targets (8) presented at the convergence position (R, R1, R2) are binocularly fused.

[Object] To provide a point cloud data processing method capable of easily extracting an analysis target from entire circumference point cloud data acquired by a measuring device that is moving along a measurement route. [Solution Means] A trajectory of a measuring device 20 is calculated based on measurement data acquired by the measuring device that is moving along a measurement route, and on a vertical plane orthogonal to the trajectory, a two-dimensional figure is identified by designating an extraction angle range around an intersection P of the trajectory and the vertical plane based on a perpendicular drawn down to a horizontal plane from the intersection and an extraction distance range based on the intersection P on the vertical plane, and a region obtained by extending the two-dimensional figure along the trajectory is set as an extraction region, and point cloud data in a region including a specific analysis target is extracted as extracted point cloud data from entire circumference point cloud data acquired by scanning the circumference of the measuring device and included in the measurement data.

Provided is a survey system that makes it possible for a worker to smoothly perform a survey work alone. A survey system (1) is provided which includes a surveying instrument (2) capable of performing distance and angle measurements of a target (7) attached to a pole (5), a controller (3) as a glove-shaped wearable device to be worn on a hand of a worker, and configured to transmit commands to the surveying instrument (2) from an input unit (34) for inputting commands, and an eyewear device (4) 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 (4), and by inputting a command by a worker from the glove-shaped controller (3) that the worker wears into the surveying instrument (2) while the worker grips the pole (5), 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.
