CNN-based Feature Extraction for Robotic Laser Scanning of Weld Grooves in Tubular T-joints
Mjølhus, Øyvind Wormdal; Cibicik, Andrej; Njaastad, Eirik B; Egeland, Olav (Chapter, 2022)This paper presents an algorithm for feature point extraction from scanning data of large tubular T-joints (a subtype of a TKY joint). Extracting such feature points is a vital step for robot path generation in robotic ... -
Generation of rule-adhering robot programs for aluminium welding automatically from CAD
Tran, Tuan Anh; Njaastad, Eirik B; Midling, Ole Terje; Bjelland, Morten; Lobov, Andrei (Peer reviewed; Journal article, 2023)This paper presents a method to automatically generate robot welding programs from CAD to address the ever-constant demand for product customisation. Furthermore, to ensure that proper welding operations and structural ... -
Identification of the geometric design parameters of propeller blades from 3D scanning
Njaastad, Eirik B; Steen, Sverre; Egeland, Olav (Peer reviewed; Journal article, 2022)This paper presents a new method for the identification of geometric design parameters of ISO 484 class propeller blades from scanned point cloud data. The method can be used for tolerance inspection and in-line measurement ... -
Robotic weld groove scanning for large tubular T-joints using a line laser sensor
Cibicik, Andrej; Njaastad, Eirik B; Tingelstad, Lars; Egeland, Olav (Peer reviewed; Journal article, 2022)This paper presents a novel procedure for robotic scanning of weld grooves in large tubular T-joints. The procedure is designed to record the discrete weld groove scans using a commercially available line laser scanner ... -
