Three dimensional representation of a remote structure using reflectorless total station instrument

Abstract EN

Remote structures and objects are always make a great measuring challenge to the engineers and surveyors.

Even with the introduction of the EDM instrument, a reflector has to be placed at the observed point.

In this study, a reflectorless total station instrument works with red light laser was used.

The objective is to measure and visualize the 3d coordinates of a remote roof dome.

330 points were observed from 5 control points.

For this purpose the instrument was checked and the spatial accuracy was in the range of 2mm.

Points were imported to the AutoCAD software and it was possible to present the data in different forms.

Contour lines, sections shaded 3d surface are presented.

Deviations of the surface from the perfect spherical shape were measured.

Polynomial surface was generated to fit the point cloud.
