Abstract: Provided is a survey method using a position acquiring device that acquires position coordinates of a worker and a mobile terminal capable of communicating with the position acquiring device. the mobile terminal sets an advancing direction of observation and a first measurement point in three-dimensional design data, and makes the position acquiring device acquire position coordinates of the worker, the mobile terminal guides the worker to the first measurement point, makes the position acquiring device acquire position coordinates of the worker at the first measurement point, and sets a point nearest from the first measurement point in the advancing direction as a second measurement point, and after that, a position of the worker, setting of a next measurement point, and guidance to the next measurement point are repeated.

Abstract: A three-dimensional survey apparatus includes a collimating ranging unit, a scanner unit, and a control calculation portion. The control calculation portion executes control to acquire, based on a survey result of the collimating ranging unit, three-dimensional data related to a characteristic portion of the measurement object which is present between a plurality of pieces of three-dimensional data that are included in point cloud data having been acquired by the scanner unit and of which the three-dimensional data has not been acquired by the scanner unit, and to add the three-dimensional data related to the characteristic portion of the measurement object having been acquired based on a survey result of the collimating ranging unit to the point cloud data having been acquired by the scanner unit.

Abstract: A surveying assistance device is a computer configured to read design information including center point data of a center point set on a centerline of a route and constituent point data of constituent points set on a section including the center point, the section being orthogonal to the centerline, acquire position information indicating a current position of a surveyed device with a predetermined period, creates a plan view from the design information and display the plan view on a terminal screen unit, display the current position on the plan view and updates the display every time the position information is acquired, record the acquired position information in a storage as an observation data, and display reference lines indicating positions which are distant from the designated section backward and forward in a route direction by a preset distance limit on the plan view.

Abstract: A method of placing a slope staking tool including pickets, crossbeams, and a slope beam. The staking method includes: placing the pickets near an intersection C between a current ground and a plane S including a designed slope s; placing the crossbeams on the pickets placed, so as to cross the pickets; searching for a point where a height difference Δh between a predetermined point on the crossbeam and the plane S including the designed slope s, calculated by a surveying device, is zero; and placing, on the crossbeams, the slope beam inclined from the point where the height difference Δh is zero as found in the search step, toward the intersection C between the current ground and the plane including the designed slope.

Abstract: Provided is a technology that enables even a beginner to easily perform finished shape observation by following precautions for use of a GNSS. A finished shape observation system includes a reference station, a mobile station, and a mobile terminal, wherein the mobile terminal includes a mobile station first confirming unit configured to confirm whether a slope distance between the reference station and the mobile station is larger than a prescribed value when measuring each of the observation points, a mobile station second confirming unit configured to confirm whether a slope distance between a first known point and the mobile station is larger than a prescribed value when measuring each of the observation points, and a mobile station third confirming unit configured to confirm whether an elapsed time from a measurement time of the first known point exceeds a prescribed value when measuring each of the observation points.

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.
