SURVEYING APPARATUS

A surveying apparatus has a combined structure of a total station and a laser scanner. The surveying apparatus includes a point cloud data acquiring unit, an abnormal part detecting unit, an abnormal part position acquiring unit, and an automatic sighting controller. The point cloud data acquiring unit acquires first point cloud data and second point cloud data obtained by laser scanning that is performed on an object to be inspected at a time interval. The abnormal part detecting unit calculates a difference between the first and second point cloud data to detect a part of the object to be inspected, at which position information varies, as a detailed-inspection target part. The abnormal part position acquiring unit acquires a position of the detailed-inspection target part. The automatic sighting controller controls to make the total station sight the detailed-inspection target part, based on the position of the detailed-inspection target part.
