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

A three-dimensional survey method executed by a three-dimensional survey apparatus which includes:

• a collimating ranging unit which irradiates a measurement object with first ranging light by collimation of a telescope portion to measure a distance to the measurement object and to detect a direction of the collimation;
• a scanner unit which is integrally provided with the collimating ranging unit and rotatably provided relative to the collimating ranging unit and which acquires point group data with respect to the measurement object by performing rotational irradiation with second ranging light to measure a distance to the measurement object and to detect an irradiation direction of the second ranging light;
• and
• a control calculation portion which is provided in at least one of the collimating ranging unit and the scanner unit,
• the three-dimensional survey apparatus acquiring three-dimensional data of the measurement object, wherein the three-dimensional survey method comprises the steps of:
• storing coordinates of a machine reference point of the collimating ranging unit and a direction of a reference collimation of the telescope portion by a backsight at a survey start position;
• storing first point group data acquired at a movement source position by controlling the scanner unit;
• storing a direction of a first collimation of the telescope portion oriented from the movement source position toward a movement destination position;
• storing 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 between the movement source position and the movement destination position;
• calculating and storing 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
• storing second point group data acquired at the movement destination position by controlling the scanner unit.

A three-dimensional survey program executed by a computer of a three-dimensional survey apparatus which includes:

• a collimating ranging unit which irradiates a measurement object with first ranging light by collimation of a telescope portion to measure a distance to the measurement object and to detect a direction of the collimation;
• a scanner unit which is integrally provided with the collimating ranging unit and rotatably provided relative to the collimating ranging unit and which acquires point group data with respect to the measurement object by performing rotational irradiation with second ranging light to measure a distance to the measurement object and to detect an irradiation direction of the second ranging light;
• and
• a control calculation portion which is provided in at least one of the collimating ranging unit and the scanner unit,
• the three-dimensional survey apparatus acquiring three-dimensional data of the measurement object, wherein
• the three-dimensional survey program causes the computer to execute the steps of:
• storing coordinates of a machine reference point of the collimating ranging unit and a direction of a reference collimation of the telescope portion by a backsight at a survey start position;
• storing first point group data acquired at a movement source position by controlling the scanner unit;
• storing a direction of a first collimation of the telescope portion oriented from the movement source position toward a movement destination position;
• storing 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 between the movement source position and the movement destination position;
• calculating and storing 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
• storing second point group data acquired at the movement destination position by controlling the scanner unit.
