基于逆向工程技術(shù)的人體牙模三維模型重構(gòu)
[Abstract]:Because the human tooth mold is composed of very complicated free-form surface, it is difficult to design. The measurement data of traditional dental model are measured directly in gypsum model by Vernier caliper, which will cause great errors, and there will be many defects in the application of gypsum model in clinical medicine. In order to explore the feasibility of clinical application of Guang Min resin model, reverse engineering and rapid prototyping were used to reconstruct 3D model. Firstly, a large number of point cloud data are obtained by scanning gypsum model with 3D non-contact scanner, then the point cloud data processing and CAD 3D model reconstruction are completed by Geomagic Studio software, and 3D entity is generated. The resin solid model was printed out by using SPS450 model 3D printer. Finally, some important data of gypsum model and resin model have been measured by using three coordinate contact measuring instrument. The data obtained from the experiment are compared and analyzed. The results show that the errors of the measured data are all in 1mm. Within the allowable error range, meet the medical requirements.
