Abstract: When a camera and a surveying device are connected by a synchro cable, and a photographing condition obtaining unit obtains a photographing start time of the camera, a survey control unit makes a survey time measurement unit start time measurement. After the camera and the surveying device are disconnected, the survey control unit starts a survey by a predetermined surveying period ΔT when tracking of the prism starts. Based on the time measurement by the survey time measurement unit, the survey control unit associates the survey result with the photographing position of each image taken by the camera to generate the data for photogrammetry.

Abstract: Provided is a three-dimensional position measuring system, a three-dimensional position measuring method, and a measuring module with which measurement can be performed without a special operation constraint even in state where a measuring module is inclined. The three-dimensional position measuring system includes a measuring module that includes a target, an omnidirectional camera, and a triaxial accelerometer, and is grasped a positional relationship among the target, the omnidirectional camera, and a measurement point, and a surveying instrument including a light output section that outputs light toward the target and a measurement section that performs distance measuring and angle measuring to the target. Since the measuring module including the target is equipped with the omnidirectional camera and the triaxial accelerometer, a posture direction of the measuring module can be identified.

Abstract: An external controller specifies the direction of a surveying instrument with respect to a laser marking instrument to calculate a first relative angle as an angle relative to the surveying instrument, calculates a second relative angle as an angle relative to a target line based on design information, and calculates a differential angle between the first relative angle and the second relative angle, thereby rotating a marking laser emitter by the differential angle to project marking laser light onto the target line.

Abstract: An apparatus and method are provided that can identify an array direction of a measurement object formed in a linear shape and efficiently perform a localized measurement of the measurement object. A measurement apparatus includes a distance measuring unit, a deflecting unit which deflects a direction of emission of measurement light with respect to a reference optical axis and which is capable of performing scanning with the measurement light with respect to a prescribed center in a circumferential direction, and a calculation control unit which controls the distance measuring unit and the deflecting unit. The calculation control unit detects coordinates of intersection points of a measurement object formed in a linear shape and a scanned trajectory of the measurement light with the basis of a distance measurement result by the distance measuring unit and the direction of emission that is deflected by the deflecting unit, and identifies an array direction of the measurement object on the basis of the coordinates of a plurality of intersection points.
