In the face of the measurement task of the contour surface of some mural panel components in the process of modern aircraft assembly and manufacturing, the single digital measurement equipment can no longer meet the measurement requirements. Therefore, the combined measurement technology based on laser tracker and articular arm measuring machine is studied in this paper. Firstly, the combined measurement system was built, and then the measurement process of the combined measurement system was developed and analyzed, and the deviation vector diagram and deviation distribution chromatogram were obtained. Finally, the combined measurement technology scheme was applied to the measurement task of the contour surface of a certain type of fuselage wall panel component. Through case analysis, the scheme is effective and feasible, and has certain application value.
