Aiming at the difference of measuring technology needed for the assembly of large and complex aircraft structural parts

a collaborative measurement method based on Metronor dual-camera tracking system

hand-held light pen and Aicon scanner was developed. The hand-held light pen and three-dimensional scanner measurement were proposed

the technical scheme omits the work of attaching and removing the reflective mark points

and the testing process in the space of 4m×3m×2m with the measurement error of no more than 0.075mm

which can realize the measurement of internal hidden features

hole position information

axis

mating surface

aerodynamic profile and the gap step

meets the requirements of three-dimensional digital measurement for large complex structures assembly on aircraft.
