Laser scanner system and registration method of point cloud data

摘要

The invention provides a laser scanner system, which comprises a laser scanner which includes a distance measuring unit for receiving a reflection light of a distance measuring light from an object to be measured and performing a distance measurement, a scanning unit for rotatably irradiating the distance measuring light, a directional angle detecting unit for detecting an irradiating direction of the distance measuring light, a GNSS device, and a control arithmetic unit, wherein the laser scanner is installed at two points, and wherein the control arithmetic unit obtains global coordinates of installation positions of the laser scanner from the GNSS device respectively, scans the distance measuring light over a total circumference at each of the installation positions, acquires point cloud data of the total circumference, performs a shape matching of the two point cloud data and combines the two point cloud data.
