**Description**
One of the main characteristics of aircraft assembly is assembly measurement accuracy. The key impact factor of measurement process for aircraft product assembly is quality of the measurement accuracy. For an analytical surface, a single digital measurement device can meet the requirements. But for the synthetic surface such as fuselage panel components, a single digital measurement device cannot meet the measurement requirements. The aim of this research is the establishment of a combined measurement method. The method demonstrated the combination of the laser tracker and the articulated arm measuring machine. In this research, the combined measurement system is constructed based on the complexity of the fuselage panel. Then the measurement process of the combined measurement technique drew up and the measurement data processing method was analyzed. Finally, the deviation vector matrix and the chromatogram deviation distribution are obtained. Employee the combined measurement method, a certain type of contour surface measuring task of the fuselage panel is completed. Through experimental analysis, the innovation is efficient and feasible. Also, it has a certain application value in the modern aerospace industry.
