Abstract: The surveying device main unit includes: a distance-measuring light-emitting unit; a light-receiving unit; a distance-measuring unit; an optical axis-deflecting unit; an emitting direction-detecting unit; and an arithmetic control unit. The arithmetic control unit controls two-dimensional scanning with a scanning pattern having an intersection at which an outward passage and a return passage of the two-dimensional scanning intersect, updates three-dimensional data of the measurement target each time a light-receiving signal is detected during the two-dimensional scanning, generates weights for detecting a reference point of the measurement target and for detecting a rotation angle of the measurement target in accordance with the distance from the intersection, each time the three-dimensional data is updated, and tracks the measurement target based on the reference point position and the rotation angle of the measurement target calculated using the weights.

Abstract: The light wave distance meter is disclosed, including: a distance measuring light-emitting unit; a light-receiving signal generating unit; and a control arithmetic unit. A light-receiving signal includes a first intermittent light-receiving signal corresponding to a first distance measuring light, a second intermittent light-receiving signal corresponding to a second distance measuring light, a third intermittent light-receiving signal corresponding to a third distance measuring light, and a fourth intermittent light-receiving signal corresponding to a fourth distance measuring light. The control arithmetic unit executes an error determination control to acquire a shift signal generated by shifting at least a phase of any one of the first to fourth intermittent light-receiving signals by 2π·n−π/2 or 2π·n+π/2, and compares the phase of the shift signal and the phase of the intermittent light-receiving signal at least between either the first frequencies or between the second frequencies.

Abstract: The inclination sensor includes a gimbal mechanism rotatably supported around a first shaft and a second shaft, a first motor, a second motor, an acceleration sensor disposed in the gimbal mechanism with an origin point of coordinate axes being coincident with a point of intersection of a shaft center of the first shaft and a shaft center of the second shaft, and a control unit that simultaneously rotates the first shaft and the second shaft to continuously rotate the acceleration sensor around the first shaft and the second shaft and applies frequency analysis to the output values from the acceleration sensor to arithmetically determine the inclination angle with respect to the horizontal direction.
