The present application relates to the emerging
software technology field about
processing classification, and especially relates to a
hull part intelligent classification method and
system based on internal and external contour features. Based on the
hull part drawing, a structured part object
list is generated, the internal structure features and the external contour features of the part are extracted, and a multi-dimensional
feature vector set is constructed; based on the preset weight configuration of each dimension, the multi-dimensional
feature vector is processed by the K-means clustering
algorithm based on weighted
Euclidean distance, and the clustering allocation result is output; the contour coefficient of the part is calculated, the CH index is calculated, and the classification effect is output according to the contour coefficient and the CH index. By extracting the internal and external contour features of the part, constructing the multi-dimensional
feature vector, and classifying based on the K-means clustering
algorithm based on weighted
Euclidean distance and evaluating the classification by the contour coefficient and the CH index, high-precision and high-process-fitting-degree classification is realized, and the classification efficiency and consistency are improved.
