The objective of the present study was to evaluate the precision and accuracy of facial anthropometric measurements obtained through digital 3-D surface photogrammetry with the DSP 400 system in comparison to traditional 2-D photogrammetry. Fifty plaster casts of cleft infants were imaged and 21 standard anthropometric measurements were obtained. For precision assessment the measurements were performed twice in a subsample. Accuracy was determined by comparison of direct measurements and indirect 2-D and 3-D image measurements. Precision of digital surface photogrammetry was almost as good as direct anthropometry and clearly better than 2-D photogrammetry. Measurements derived from 3-D images showed better congruence to direct measurements than from 2-D photos. Digital surface photogrammetry with the DSP 400 system is sufficiently precise and accurate for craniofacial anthropometric examinations.
本研究的目的是评估通过DSP 400系统的数字三维表面摄影测量法获得的面部人体测量的精度和准确性，并与传统二维摄影测量法进行比较。对50例唇腭裂婴儿的石膏模型进行成像，并获得21项标准人体测量数据。为了进行精度评估，在一个子样本中进行了两次测量。通过直接测量与间接二维和三维图像测量的比较来确定准确性。数字表面摄影测量法的精度几乎与直接人体测量法一样好，且明显优于二维摄影测量法。三维图像得出的测量结果与直接测量结果的一致性比二维照片更好。使用DSP 400系统的数字表面摄影测量法对于颅面部人体测量检查而言足够精确和准确。
