REGISTRATION AND FEATURE EXTRACTION FROM TERRESTRIAL LASER SCANNER POINT CLOUDS FOR AEROSPACE MANUFACTURING

Abstract. Aircraft wing manufacture is becoming increasingly digitalised. For example, it possible to produce on-line digital representations of individual structural elements, components and tools as they are deployed during assembly processes. When comes monitoring a manufacturing environment, imaging systems can be used track objects move about the workspace, comparing actual positions, alignments, spatial relationships with representation process. Active such laser scanners trackers capture measurements within which deduce information both overall stage progress tasks. This paper concerned in-line extraction location orientation drilling templates hand ensure drilled holes accurately located. In this work, construction grade terrestrial scanner, Leica RTC360, an example aircraft section in mid-assembly from several scan locations. Point cloud registration uses 1.5” white matte spherical targets that interchangeable SMR by AT960 MR tracker, ensuring scans connected established metrology control network define coordinate space. was achieved sub-millimetre accuracy when compared tracker network. The on surface skin automatically extracted captured registered point clouds. referenced hole centres, scanner template agree 0.2mm.
