Method for automatically extracting feature points of digital model of preoperative nasal-alveolar process appliance

The invention discloses a method for automatically extracting feature points of a digital model of a preoperative nasal-alveolar process appliance. The method comprises the following steps: S1, acquiring an oral impression model file and preprocessing the oral impression model file; S2, performing coordinate system transformation on the preprocessed oral impression model; S3, performing segmentation processing on the oral impression model after coordinate system transformation; S4, performing two-dimensional plane projection on digital models of the alveolar bones on the two sides, and performing image fitting on the projected images of the alveolar bones on the two sides to obtain a fitting graph; and S5, performing side plane projection on the alveolar bones of the healthy side and the affected side according to the fitting graph, segmenting a ridge line according to the side plane projection, and extracting feature point coordinates according to the trend of the ridge line. Dimension reduction processing is performed on three-dimensional digital model data, and feature points are extracted by using image fitting and feature recognition technologies; the method can provide guidance for the design of a preoperative cleft lip and palate correction model, reduces the operation risk, improves the correction success rate, and has good commercial prospect and values.
