REGISTRATION AND FEATURE EXTRACTION FROM TERRESTRIAL LASER SCANNER POINT CLOUDS FOR AEROSPACE MANUFACTURING [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2022 Aircraft wing manufacture is becoming increasingly digitalised. For example, it is becoming possible to produce on-line digital representations of individual structural elements, components and tools as they are deployed during assembly processes.

Mathematical model of laser tracker measur-ing system for multiple control of large constructions
Вестник Самарского государственного технического университета. Серия: Технические науки, 2022 Laser trackers are widely used to non-contact measure large-scale aerospace products. If it is impossible to inspect the entire product with a single laser tracker with a fixed position, multi-station inspection is used.
