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.

Survey method, mobile terminal, survey system, and storage medium

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.

Three-dimensional survey apparatus, three-dimensional survey method, and three-dimensional survey program

Provided is a surveying assistance method comprising making a computer read design information including center point data of center points set on a centerline of a route and constituent point data of constituent points set on sections including the center points, the section being orthogonal to the centerline, acquires position information indicating a current position of a surveyed device at a predetermined period, calculate a horizontal distance and a vertical distance between the current position and a reference point on a designated section based on the position information and the design information, display the horizontal distance and the vertical distance on a screen of the computer as survey information, and update the display at intervals of the predetermined period, and the reference point is a point to be selected from the center points or the constituent points.

Surveying assistance device, surveying assistance system, surveying assistance method, and storage medium

A surveying system including a surveying device and a terminal device for assisting in placement of a staking tool. The surveying system further includes: a design information acquisition unit for acquiring design information including a designed slope; a surveying information acquisition unit for transmitting surveying information to a terminal device; a current state estimation unit for calculating an estimated altitude of a current ground in accordance with the surveying information; an intersection calculation unit for calculating a coordinate of an intersection between the current ground and the designed slope based on the estimated altitude of the current ground and the design information; a stake shape determination unit for determining a shape of a stake to be placed; and a stake shape information unit for causing the terminal device to inform of the shape of the stake determined by the stake shape determination unit.

Surveying system, staking assistance method, and storage medium storing staking assistance program

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.
