Abstract
Registering of point clouds from terrestrial laser scanning, is often carried out using spherical targets. Instead of expensive original targets, it is also possible to use other spherical elements. Such targets, encountered in practice, may be, for example, Styrofoam spheres, spheres built using 3D printers, spherical, milky lampshades. Most spheres which are used as substitutes, have a certain common feature: as a result of partial transparency of the material, the laser beam can penetrate inside, changing distance measurements. This applies both to glass spheres and a wide range of synthetic products. These materials may therefore have a negative effect on the accuracy of determining the centers of the reference spheres and, consequently, the accuracy of registration point clouds in neighbouring scanners’ positions. This paper presents the results of the research studies allowing to assess this effect. Both the accuracy of determining the centers of the spherical targets, as well as the displacements occurring in the point clouds merged with their use were determined.
