Development of a new testfield to model errors in terrestrial laser scanner data

Laser scanner technology due to having capabilities in comparison with other surveying methods, is favoured by the users increasingly. However, almost there are different factors that affected the results of this instrument. Thus, the accuracy of the scanner is limited extensively by the systematic instrument errors and thus must be calibrated. In fact calibration is a prerequisite for extracting 3D precise and reliable data from point clouds. Test field has a great role in calibration procedure. so different test fields have been assessed for this purpose so far. In this paper, a new method is presented for constructing a test field in a virtual form. one of the advantages of this method is that through this method the instrument can be calibrated everywhere the project is executed but in the laboratorial conditions
