Construction method of double-path human body full-airway model for CFD (Computational Fluid Dynamics)

The invention discloses a construction method of a double-path human body full-airway model for CFD (computational fluid dynamics) simulation, and belongs to the field of bio-fluid mechanics. Comprising the steps that (1) a CT image of the upper body of a human body is received, medical image reconstruction and reverse engineering are combined, an upper respiratory tract-bronchial tube model based on the CT image is generated, and the model comprises a mouth model, a nose model, a throat model, a throat model, a trachea model and a bronchial tube model; (2) on the basis of a Weibel idealized model, using a parameterized script to generate a two-branch idealized 0-23-level pulmonary airway model which comprises a trachea model, a bronchus model and a deep pulmonary airway model; and (3) segmenting the upper respiratory tract-bronchus model based on the CT image, and assembling and combining the segmented upper respiratory tract-bronchus model with corresponding parts of the two branch ideal pulmonary airway mo
