Abstract (EN): This work aims at acquiring the interior shape of wind towers by means of a 3D laser scanning system (LSS). Typically, wind towers are made of structural steel sheets and their fabrication consists of rolling and welding of abutted rolled sheets. This task is typically carried out by welding robots moving through the tower structure. In this study, the developed setup consists of a camera and a circular laser module mounted on the welding robot's arm traveling through the tower with a constant velocity. The deployed system assists in examining the tower's interior surface, making it possible to obtain its 3D profile. It will therefore be beneficial for monitoring the geometric changes which occur during the welding process. Encouraging results have been achieved in the characterization of the tower's geometry, contributing to the assessment of the robustness and accuracy of the deployed 3D LSS. (C) 2019 The Authors.
