Abstract

The invention discloses a human body three-dimensional skeleton model marking method based on data driving, and the method comprises the steps: firstly converting skeleton CT scanning data into a skeleton grid model, carrying out the manual segmentation marking, and outputting a normal vector of each point and a three-dimensional coordinate of a label information combination point to a text file through employing a mapping algorithm; and training the mapped data through a multi-level PointNet++ network model to obtain a coarse-to-fine skeleton region segmentation network model, inputting the corresponding data into the hierarchically segmented PointNet++ network model to obtain a rough skeleton model segmentation result, and performing graph segmentation on the rough skeleton model segmentation result to optimize a boundary segmentation result; further extracting an anatomical mark of the skeleton template through a PointNet++ network, fitting the skeleton template to an outer surfacearea by matching the anatomical mark, mapping the anatomical mark on the template to a target skeleton, and finally obtaining a skeleton classification result and the corresponding anatomical mark.
