Abstract A method of surface reconstruction and deviation analysis of aircraft body based on digital twin was proposed. Firstly, the real data was processed, including data collection, point cloud data grids and coordinate alignment, point cloud data division based on the characteristics. Then, twin model reconstruction method was designed combined with NURBS method, and model test was carried out by the proposed method. An application example to test the method is feasible and verifies that the method has a certain application value.
