利用数码照片重建颌面部软组织三维形态的初步研究

摘要

目的:探索面部软组织三维重建的新方法.方法:采用数码相机获取被摄者两张正面数码照片,利用数字化近景摄影测量的原理和方法,在地理信息系统下进行面部软组织的三维重建.结果:实现了颌面部软组织三维重建,获得了逼真的面部软组织三维图像.结论:利用数字化近景摄影测量和地理信息系统的原理和技术,进行颌面部软组织三维重构,是软组织三维重建方法的新探索.%Objective To explore a new method about three-dimensional (3D) reconstruction of facial soft tissue. Methods Two front facial photographs of volunteer were obtained by digital camera.Then.the 3D reconstruction image was generated using close -range photogrammetry technique under the geographic information system (GIS) surrounding. Results The 3D facial soft tissue was obtained and the reconstruction was clear and real. Conclusion The digital close-range photogrammetry and the GIS principle and technique are new exploration on 3D reconstruction of soft tissue.
