Abstract: A surveying system includes a target unit having a reflection target and an encoder pattern showing an angle of the target unit; a scanner configured to acquire three-dimensional point cloud data, measured coordinates of the target, and optically read the encoder pattern to acquire an encoder pattern read angle; and a leveling base configured to selectively allow either of the target unit and the scanner to be removably mounted. The scanner calculates a direction angle of the leveling base based on the encoder pattern read angle and the offset angle of the target unit, calculates coordinates of an installation point of the target unit based on the measured coordinates of the target and the direction angle of the target, and calculates a direction angle of the scanner based on the offset angle of the scanner and the direction angle of the leveling base on which the scanner is mounted.

Abstract: Provided is a scanner system includes a laser scanner and a remote controller thereof. The remote controller includes a guide light transmitting unit. The laser scanner includes a guide light receiving unit for detecting the guide light transmitting unit. The laser scanner directs the optical axis of distance-measuring light to the guide light transmitting unit based on a light reception signal and set a data exclusion range with reference to the direction of the guide light transmitting unit. The laser scanner remeasures point cloud data of the data exclusion range in accordance with a measurement permission from the remote controller upon measuring point cloud data of an entire measurement range, and deletes the point cloud data of the data exclusion range from the point cloud data of an entire measurement range, and replacing the deleted data with remeasured point cloud data to acquire entire point cloud data.
