According to the measurement technology requirements of aircraft assembly for large-volume

high precision

strong compatibility

good expansibility and fast networking

the research on establishment technology of large-volume multi-system measurement field for aircraft assembly is carried out

the principle of measuring reference optimization design is proposed and the multi station redundant measurement length constraint algorithm is adopted based on laser tracker. A 3D precision reference measurement field compatible with aircraft assembly equipment is constructed

and the calibration accuracy of the reference field is verified by experimental comparison. Eventually

through a typical application case

this paper expounds the construction technology of large-volume multi-system measurement filed in the process of aircraft assembly

which promotes the improvement of aircraft assembly measurement technology.
