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.

Abstract: 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.

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.
