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 ... -
Polarization image laser line extraction methods for reflective metal surfaces
Marco Rider, Jaime; Cibicik, Andrej; Egeland, Olav (Peer reviewed; Journal article, 2022)In this work, we propose a novel pipeline method for laser line extraction from images with a polarization image sensor. The proposed method is specially developed for strong laser beam reflections from metal surfaces. For ... -
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 ... -
Supporting robotic welding of aluminium with a laser line scanner-based trigger definition method
Marco Rider, Jaime; Tran, Tuan Anh; Njåstad, Eirik; Egeland, Olav; Lobov, Andrei (Chapter, 2022)Automation and the use of robots for welding operations is an important research topic. Being able to automate and, thus, save time for setting up and using robotic welding for complex, large-scale structures made of ...
