Abstract：Digital measurement technology and system are the important component of modern digital technology in aircraft assembly,which is applied in the assembly process of modern aircraft, not only ensure the accuracy of aircraft assembly, but improve the production efficiency,the full digital transmission is achieved from part design and manufacture to assembly process of aircraft products simultaneously.Several digital measurement systems are studied, which are widely used in aircraft assembly currently including laser tracker measurement system, three-dimensional laser scanning system,digital camera measurement system and indoor GPS system, the working principle and characteristics of the system are described and its application in aircraft assembly is discussed. According to the requirement of developing the digital assembly technology in the domestic, the application of digital measurement technology and system is prospected.
