THREE-DIMENSIONAL SURVEY APPARATUS, THREE-DIMENSIONAL SURVEY METHOD, AND THREE-DIMENSIONAL SURVEY PROGRAM

To provide a three-dimensional survey apparatus, a three-dimensional survey method, and a three-dimensional survey program which are capable of executing registration of point cloud data in an efficient manner. A three-dimensional survey apparatus includes a collimating ranging unit, a scanner unit, and a control calculation portion. The control calculation portion calculates and stores coordinates of a machine reference point of the collimating ranging unit at a survey position by collimation of a telescope portion, stores point cloud data having been acquired at the survey position by controlling the scanner unit, and executes control for performing, based on the stored coordinates of the machine reference point, positioning of the point cloud data having been acquired by the scanner unit.
