【摘要】：颜面部软组织三维图像信息的获取方法有莫尔云纹、激光扫描和三维立体摄影测量。莫尔条纹法具有成本低、非介入性等优点,但其面部重建还是不够直观且灵敏度较低。激光扫描精度高,立体重构快捷逼真;但其易伤害眼睛,只捕捉表面形貌,无法观察软组织质地;数据采集时间较长,易增加运动伪影。三维立体摄影测量为非介入性的,安全无创;拍摄迅速,图像采集时间短,无运动伪影的风险;数据存储方便,查询快捷,可对归档的图像进行后续的反复分析;提高了测量速度和精度;与被检查对象无接触;医师与患者间的沟通更加便捷,有利于医师设计和调整更符合患者要求的个体化治疗方案。三维立体摄影测量也令今后正畸和正颌专家的远程网上诊疗成为可能,有可能成为口腔颜面部修复重建的常规检查项目。
[Abstract]:The methods of obtaining 3D image information of facial soft tissue include moire, laser scanning and three-dimensional photogrammetry. Moir 茅 fringe method has the advantages of low cost and non-interventional, but its facial reconstruction is not intuitive and sensitive. Laser scanning accuracy is high, stereo reconstruction is quick and realistic; but it is easy to hurt the eyes, only capture the surface morphology, can not observe the soft tissue texture; the data acquisition time is longer, easy to increase the motion artifacts. 3D stereoscopic photogrammetry is non-interventional, safe and non-invasive, rapid shooting, short image acquisition time, no risk of moving artifacts, convenient data storage, quick query, and can be used for repeated analysis of archived images. It improves the measuring speed and accuracy, has no contact with the object under examination, and the communication between the physician and the patient is more convenient, which is helpful for the physician to design and adjust the individualized treatment plan which meets the patients' requirements. Three-dimensional photogrammetry also makes it possible for orthodontics and orthognathic experts to make remote online diagnosis and treatment in the future.
