Multi-baseline Digital Close-range Photogrammetry Technology in Oral Facial Three-dimensional Imaging and Measurement

目的:探讨多基线数字近景摄影测量技术在口腔颜面部三维成像和测量中的应用。方法:应用普通数码相机对口腔颜面部进行拍摄并获得多幅重叠无序的照片,采用多基线数字近景摄影系统对照片进行处理。结果:对颜面部组织长度及宽度测量上与传统手工测量方法相比无统计学差异(P>0.05)。结论:多基线数字近景摄影测量技术操作简单、测量准确、对设备要求低,可用于口腔颜面部三维成像的测量中。

Objective： To investigate the multi-baseline digital close-range photogrammetry technology in oral facial three-dimensional imaging and measurement. Methods： Ordinary digital camera on oral facial plaster model shoot and get multiple overlapping photos disorder, the use of multi- baseline digital close-range photogrammetry system for photo processing. Results： No statistically significant difference （P〉0.05） based on the facial bone length and width measurements compared with traditional manual measurement methods. Conclusion： Simple multi-baseline digital close-range photogrammetry technology, accurate measurement of low equipment requirements and can be used three-dimensional imaging of oral facial measurements.
