3D 측정 기기를 이용한 얼굴의 부피 정량법 연구

The evaluation for the visage volume was performed with human and dummy face using PRIMOS bodyⓇ. Three researchers measured the dummy face attached different volume of clay (6.6 mL, 13.2 mL, and 19.8 mL). It is identified that the high correlation between measured values and real volume (R2 = 0.99). The percent (%) of relative standard deviation (RSD) of the data was shown below 10 %. In Gage R&R analysis, the percent of contribution, the percent of study variation and distinct categories values were 0.78 %, 8.85 %, and 15 % respectively. Therefore this method was regarded as the good standard condition in aspect of reproducibility and repetitiveness of data. The face volume variation was measured by PRIMOS bodyⓇ on the face in participated 10 healthy Korean women volunteers. Subjects used the product once a day for two weeks as night sleeping pack. After application of the test products, the 3D image data of face were taken 1 and 2 weeks later. We found the face volume was significantly decreased after using products. In conclusion, this novel non-invasive technique was useful in measuring and visualizing alterations in face volume as a consequence of certain treatments. This system will provide a rapid and precise analysis of 3D topographical information for face.
