Terrestrial Laser Scanning (TLS) in LiDAR technology is a commonly used method in obtaining geometric information about objects. Individual scan stations can be combined into one project using the cloud-to-cloud method or based on targets (chessboards or spheres). Target-based registration with spheres is very convenient because in planar view always circle is visible, no matter of the angle of view. On the other hand, it is inconvenient to use the same size of spheres throughout the project. Large spheres are eas...
