Comparison of 3D laser scanning and classical survey data deformation analysis of industrial facilities in oil refinery

Terrestrial laser scanning is an advanced measuring technology, which can record a huge number of data with high accuracy. Because of its characteristics, nowadays it has established itself in many fields, like forensics, architecture, civil engineering, archaeology, etc., but for some uses classical geodetic methods are still unsurpassed or at least a standard for comparison with modern methods like 3D laser scanning. In this paper, a specific example of 3d deformation analysis on industrial facility in the Oil refinery Sisak is described. Industrial survey, and deformation analysis is a very demanding part of geodesy, so it requires high density and high data accuracy. The water pump in oil refinery Sisak was measured with a terrestrial laser scanner in order to define geometry, to create a model and to find out if there are deformations present on the pump which cause small vibrations that damage the facility during long runs. For this purpose, we will try to show that using high precision modern laser scanner and two different independent software approaches, one commercial and the other, own program written in Matlab, can get solutions of deformation analysis with accuracy comparable to conventional surveying methods. It was shown that the use of laser technology is highly effective. It can very precisely define and analyse the object with incomparably better visualization of corresponding output data than the use of classic geodesic methods with the same order of accuracy.
