Abstract The assembling of the new generation aircraft is characterized by high precision, high efficiency and high reliability. By considering the characteristics, the demands of geometric measurement during assembling are analyzed and the measurement system is established. Three key techniques are accomplished. The first one is multi-source heterogeneous whole-body measurement process simulation and accuracy optimization technique. The second one is 3D point cloud data fitting and aligning technique. The third one is multi-system collaboration and cross-scale measurement technique based on whole-body measurement field. The aircraft assembling quality management platform is then developed. The measurement data management informatization is also achieved. The techniques and measurement system will offer data support for the following assembly work and improve the quality controllability of assembling process.
