Embodiment Construction

[0032] Below in conjunction with embodiment the present invention is described in further detail.

[0033] Example.

[0034] according to figure 1 As shown in the process of the present invention, this embodiment first collects 30 small samples of normal auricles on the basis of reviewing the literature to conduct research and analysis on the anatomical shape of the auricles, find 20 indicators to describe the auricle shape through the geometric analysis method, and analyze the shape of the auricle through statistical analysis. Based on the analysis and combination of professional knowledge, 4 personalized indicators describing the concept of the auricle and 16 refined indicators describing the fine structure of the auricle were selected. The personalized indicators are total ear length, ear width, ear cranial angle, and earlobe shape, and the refined indicators are as follows (cluster analysis is performed on the refined indicators in this example). At the same time, accord...

Abstract

The invention discloses a personalized auricle data model building method based on normal auricle morphological classification. Classification indexes for describing a precise auricle structure and building indexes of the personalized data model for describing a basic auricle shape are included. On one hand, data measuring is carried out on auricle indexes, the position of a crus of helix serves as a boundary for partitioned clustering analysis to obtain the auricle data model; on the other hand, according to personalized index data, the personalized auricle data model is further obtained on the basis of the data model obtained through normal auricle classification. Compared with traditional auricle visual modality description and classification, the data model in the method is obtained after clustering analysis of quantitative auricle morphological indexes, so that classification is more accurate, standard and objective, and real auricle information can be reflected better. The personalized auricle data model built due to the fact that personalized index values are introduced into the auricle data model has significant meaning in manufacturing personalized ear cartilage supports and further reconstructing personalized auricles.

Description

technical field [0001] The invention relates to the field of anatomical morphological classification of adult body surface tissues and organs and data model construction, in particular to the construction of a personalized auricle data model based on normal auricle morphological classification. Background technique [0002] The external auricle is an important part of the aesthetics of the facial features of the human body. It is also the organ with the most complex shape and the most delicate three-dimensional structure. It also plays an important role in collecting and converging sound waves. Congenital microtia is a common body surface disease that requires plastic repair. The mechanism of its occurrence is due to the abnormal development of the first and second branchial arches during the embryonic period, resulting in congenital dysplasia of the ear cartilage. The complexity and delicacy of the external auricle and people's endless pursuit of beauty make microtia auricl...
