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

A three-dimensional survey method, which is executed by a three-dimensional survey apparatus, the three-dimensional survey apparatus acquiring three-dimensional coordinates of a measurement point with respect to a measurement object and including:

• a collimating ranging unit which irradiates the measurement object with first ranging light by collimation of a telescope portion and which, based on first reflected ranging light that is reflection of the first ranging light by the measurement object, measures a distance to the measurement object and detects a direction of the collimation to acquire the three-dimensional coordinates;
• a scanner unit which is integrally provided with the collimating ranging unit and rotatingly emits second ranging light and which, based on second reflected ranging light that is reflection of the second ranging light by the measurement object, measures a distance to the measurement object and detects an emission direction of the second ranging light to acquire point cloud data comprising a plurality of the three-dimensional coordinates related to the measurement object;
• and
• a control calculation portion which is provided in at least one of the collimating ranging unit and the scanner unit, wherein
• the three-dimensional survey method comprises the step of:
• providing, if there is a first measurement location where the three-dimensional coordinates have been acquired and a second measurement location where the three-dimensional coordinates have not been acquired among the measurement object when the scanner unit acquired the point cloud data, the three-dimensional coordinates related to the second measurement location acquired by the collimating ranging unit to the point cloud data to hole-plug the three-dimensional coordinates related to the second measurement location of the point cloud data.

A three-dimensional survey program, which is executed by a computer of a three-dimensional survey apparatus that acquires three-dimensional coordinates of a measurement point with respect to a measurement object, the three-dimensional survey apparatus including:

• a collimating ranging unit which irradiates the measurement object with first ranging light by collimation of a telescope portion and which, based on first reflected ranging light that is reflection of the first ranging light by the measurement object, measures a distance to the measurement object and detects a direction of the collimation to acquire the three-dimensional coordinates;
• a scanner unit which is integrally provided with the collimating ranging unit and rotatingly emits second ranging light and which, based on second reflected ranging light that is reflection of the second ranging light by the measurement object, measures a distance to the measurement object and detects an emission direction of the second ranging light to acquire point cloud data comprising a plurality of the three-dimensional coordinates related to the measurement object;
• and
• a control calculation portion which is provided in at least one of the collimating ranging unit and the scanner unit, wherein
• the three-dimensional survey program causes the computer to execute the step of:
• providing, if there is a first measurement location where the three-dimensional coordinates have been acquired and a second measurement location where the three-dimensional coordinates have not been acquired among the measurement object when the scanner unit acquired the point cloud data, the three-dimensional coordinates related to the second measurement location acquired by the collimating ranging unit to the point cloud data to hole-plug the three-dimensional coordinates related to the second measurement location of the point cloud data.
