Low-cost distance measuring methods and their investigation for BIM modeling

Abstract

The purpose of the thesis is multifaceted. On one hand, I will investigate the feasibility of producing flat shapes that serve as the basis for different purpose BIM models, depending on reliability. On the other hand, I would like to examine separately the reliability of the various low- cost total stations nowadays, for such measurements. An earlier study dealt with the use of low-cost targets for laser scanning. In connection with this, an attempt was made to measure the extent to which the used styrofoam spheres available in decoration shops can be considered as perfect spherical shapes and whether they may have flatness.
