中文摘要 | 長期以來, Du Bois& Du Bois的腳型表面積估算式 (FSA = 1.04× FootLength x (BallGirth + AnkleGirth))被應用在工業安全,醫療等許多的方面,但是該研究的樣本代表性以及量測方法的準確性卻也一直遭受質疑。3D人體掃描技術可以克服這些問題。3D腳型掃描儀可以在短短的 6秒內量測一個腳型,其準確度達到 1mm。本研究主要目的是要應用 3D人體掃描技術重新量測並推導出 Du Bois & Du Bois的公式。本研究採用台灣 3D體型資料庫中的 3D腳型資料。這個資料庫包含了 135位男性與 135位女性受測者的 3D腳型資料。由 3D腳型資料計算出腳型表面積,以及萃取出 3個 3D腳型尺寸值,分別是腳長、腳掌圍、腳踝圍。再將表面積和 3個 1D尺寸值重新以Du Bois & Du Bois的公式進行迴歸。新的腳型表面積估算式是 FSA =1.097 × Foot Length x (Ball Girth + Ankle Girth),其R2是 95.1%。這個新的腳型表面積估算式的估算平均誤差是 1.5%,優於Du Bois & Du Bois的 5.0%估算平均誤差。 |
英文摘要 | Du Bois and Du Bois’ foot surface area (FSA) estimation formula ( FSA = 1.04 x FootLength×(BallGirth + AnkleGirth)) has been widely used in industrial hygiene, medicine and many other applications., but the number of the subjects measured and the measurement accuracy level of the covering method used in the study had been questioned still. The 3D foot scanning method can overcome these problems. The 3D foot scanner can be used to measure FSA, it completes a scan in 6 seconds with measurement accuracy level within 1 mm. This study intends to establish a new FSA formula similar to that of the Du Bois and Du Bois’ by the 3D scanning method. A Taiwanese 3D BodyBank was adopted in this study, in which the 3-D foot scanner was used to scan the 3-D foot forms. The Taiwanese 3D BodyBank recruited 135 male and 135 female subjects. The FSA was extracted from the 3D foot forms by using TriD software; and three 1-D foot measurements, including foot length, ball girth, and ankle girth, were also extracted automatically. These three measurements were used to regress on FSA similar to the form of Du Bois & Du Bois’ formula. The new FSA estimation formula is FSA = 1.097 x FootLength x (BallGirth + AnkleGirth) with a R2 of 95.1%. This new FSA estimation formula has an estimation error with 1.5%, better than that of Du Bois & Du Bois’, 5.0%. |
