Comparison of facial tissue measurements using two-dimensional and three-dimensional character acquisition system / 中国组织工程研究

ABSTRACT

Complicated characteristic of facial modality acquisition and measurement is commonly needed in clinical environment.Two different methods were compared, one method was acquisition two-dimensional character based on the principle of machine vision with a charge-coupled device (CCD) capturing image, and another method was acquisition three-dimensional character based on the technology of Reverse Engineering with laser scanning capturing image. The principle, composition of the system, calibration and characteristics of different method are analyzed. Two-dimensional and three-dimensional facial data of thirty undergraduates was used to compare different methods. The application and restriction of different methods are concluded. The conclusion of this paper provided a reference for face plastic surgery, facial paralysis, facial surgical evaluation and rehabilitation design.
