Abstract

The present invention relates to a three-dimensional model driven aircraft assembly process design method and system, and belongs to the technical field of aircraft assembly process design. The embodiment of the present invention discloses a three-dimensional model driven aircraft assembly process design method and system. The method comprises: obtaining an aircraft assembly three-dimensional model and an assembly semantic document, splitting, classifying and numbering the assembly three-dimensional model to obtain an ordered classified component model; obtaining discrete data through an interface function, retrieving assembly semantics according to the model number, constructing the ordered classified component model, discrete data set and assembly information to obtain an assembly semantic model; obtaining measured point cloud data of assembly parts, performing coordinate transformation and segmentation on the measured point cloud data to obtain point cloud blocks; correcting the assembly semantic model according to the point cloud blocks; and lightweighting the corrected assembly semantic model. The fusion of the three-dimensional model and the semantic document is realized, and the model is corrected and lightweighted through measured data.
