Ship three-dimensional material list generation method based on classification attribute features

The embodiment of the invention provides a ship three-dimensional material list generation method based on classification attribute features, and the method comprises the steps: constructing a material coding structure of a ship; preprocessing the three-dimensional model of the ship, analyzing the hierarchical structure of the three-dimensional model of the ship, and performing data processing on the three-dimensional model data set; model information is extracted, classification is carried out according to material code labels defined by ship material instances, a three-dimensional model data set is constructed into multi-label classification through a classification attribute feature and feature selection method, classification category items of corresponding classes are put in, and the classification category items are determined according to ship specialty and in combination with contained attribute features; and matching and corresponding each material coding node in the material coding structure with th
