<p>Disclosed is a survey system provided with a plurality of rotary laser devices (1a, 1b) which are installed at known points and respectively form laser reference planes (RPa, RPb) by rotationally applying laser beams (3a, 3b), a light receiving device (5) which is provided in a movable support (4), receives the laser beams, and detects the heights of the respective laser reference planes at light receiving positions, a coordinate position measuring device (6) which detects the coordinate position of the support, and a control device (7). The rotary laser devices form the laser reference planes such that at least parts of the effective areas of the laser reference planes overlap each other. The control device sets a smoothing region within a range in which the effective areas overlap each other, and when the support is located within the smoothing region on the basis of the result of measurement by the coordinate position measuring device, performs smoothing processing for causing the laser reference planes to be continuous by a smoothing reference plane in the smoothing region on the basis of the result of measurement by the coordinate position measuring device and the results of detection by the light receiving device.</p> |
