Abstract: A tilt analysis method analyzing a tilt of a columnar object is disclosed. The tilt analysis method includes: acquiring a reference value on the basis of a first position of a reflector of a measurement target device attached to a column foot portion of the columnar object; acquiring, in response to an execution instruction, a column top value on the basis of a second position of the reflector of the measurement target device attached to a column top of the columnar object, the execution instruction being received by an input section and inputted via a column top value acquisition instruction section displayed on a display section of a terminal device; generating tilt information indicating in which direction the columnar object tilts based on the reference value and the column top value; and causing the display section to display the tilt information including graphic display.

Abstract: A three-dimensional survey apparatus includes a collimating ranging unit, a scanner unit, and a control calculation portion. The control calculation portion stores coordinates of a machine reference point of the collimating ranging unit and a direction of a reference collimation of a telescope portion, stores first point group data, stores a direction of a first collimation of the telescope portion oriented from the movement source position toward a movement destination position, stores a direction of a second collimation of the telescope portion oriented from the movement destination position toward the movement source position and a movement distance, calculates and stores coordinates of the machine reference point at the movement destination position with the survey start position as a reference based on the direction of the first collimation, the direction of the second collimation, and the movement distance, and stores second point group data.

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 method using a surveying system including a surveying device and a terminal. The surveying method includes: receiving, by the terminal, a result of selecting a survey target foundation point from among a plurality of consecutive foundation points; obtaining an intersection between a reference line and a boundary side set in advance, the reference line connecting the survey target foundation point and an adjacent foundation point adjacent to the survey target foundation point; and outputting, in association with the survey target foundation point, a relative positional relationship between the intersection and a survey target device surveyed by the surveying device for the survey target foundation point.

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.
