Abstract

The present invention discloses an organism structure three-dimensional reconstruction and finite element analysis method. The method comprises the following steps of: (1) utilizing a CT tomoscanner to perform three-dimensional scanning of organism bones to obtain a tomography data file; (2) inputting the obtained tomography data file into Avizo software, performing three-dimensional model reconstruction of the organism bones, and obtaining a simplified three-dimensional model, and storing the three-dimensional model in a '.stl' file; (3) utilizing Geomagic Studio software to perform surface optimization the and model data size simplification of the organism bone three-dimensional model, converting the organism bone three-dimensional model into a CAD model, and storing the CAD model in a '.igs' format; and (4) utilizing ANSYS software to perform mathematics analysis of the organism bone three-dimensional model. According to the technical scheme of the invention, the three-dimensional reconstruction of organism structure and finite element analysis method can solve the reconstruction problem of the three-dimensional structure of the special portion of the organism in the three-dimensional model reconstruction process, the obtained three-dimensional model is high in precision, the method is simple and effective, and the format conversion of the three-dimensional model is flexible.

Description

technical field [0001] The invention relates to the technical field of three-dimensional reconstruction of organisms using computer software, point cloud data processing and reverse engineering operations, in particular to a method for three-dimensional reconstruction and finite element analysis of organism structures. Background technique [0002] The bones of living organisms are extremely irregular in shape. To analyze them by computer, we must first obtain their three-dimensional models, and then perform extremely fast processing on them such as preprocessing, meshing, and surface optimization. [0003] In the prior art, in the reconstruction process of the three-dimensional model, the specific model structure of the organism cannot be accurately extracted, and the reconstruction of the bone model of the organism is irregular, the accuracy is not enough, and the process is complicated. Contents of the invention [0004] Aiming at the deficiencies of the prior art, the ...
