Survey apparatus and survey program

A survey program to be executed by a computer of a survey apparatus including:

• a measurement unit which performs ranging by emitting ranging light toward a measurement object and receiving reflected ranging light from the measurement object;
• an imaging unit which has an imaging optical axis that is parallel to an emission optical axis of the ranging light, and which images an image including the measurement object;
• an attitude detecting unit which is integrally provided with the imaging unit and has an inclination sensor which detects horizontality and a relative inclination angle detecting portion which inclines the inclination sensor so that the inclination sensor detects horizontality and which detects an inclination angle of the measurement unit relative to the horizontality in a state where the inclination sensor detects horizontality;
• and
• a calculation processing unit,
• the survey program causing the computer to
• execute ascertaining a rough shape of the measurement object on the basis of the image including the measurement object having been imaged by the imaging unit and generating, on the basis of the rough shape, a scan pattern of the ranging light emitted by the measurement unit.
