The aim of this study was to standardize clinical photogrammetric techniques, and to compare anthropometry with photogrammetry.
To standardize clinical photography, we have developed a photographic cephalostat and chair. We investigated the repeatability of the standardized clinical photogrammetric technique. Then, with 40 landmarks, a total of 96 anthropometric measurement items was obtained from 100 Koreans. Ninety six photogrammetric measurements from the same subjects were also obtained from standardized clinical photographs using Adobe Photoshop version 7.0 (Adobe Systems Corporation, San Jose, CA, USA). The photogrammetric and anthropometric measurement data (mm, degree) were then compared. A coefficient was obtained by dividing the anthropometric measurements by the photogrammetric measurements.
The repeatability of the standardized photography was statistically significantly high (p=0.463). Among the 96 measurement items, 44 items were reliable; for these items the photogrammetric measurements were not different to the anthropometric measurements. The remaining 52 items must be classified as unreliable.
By developing a photographic cephalostat and chair, we have standardized clinical photogrammetric techniques. The reliable set of measurement items can be used as anthropometric measurements. For unreliable measurement items, applying a suitable coefficient to the photogrammetric measurement allows the anthropometric measurement to be obtained indirectly.
本研究旨在规范临床摄影技术，并比较人体测量学与摄影测量学。
为了使临床摄影标准化，我们开发了一种摄影头颅定位器和椅子。我们研究了标准化临床摄影技术的可重复性。然后，在 100 名韩国人中，用 40 个标志点共获得了 96 个人体测量项目。使用 Adobe Photoshop 版本 7.0（Adobe Systems Corporation，San Jose，CA，USA）从相同受试者的标准化临床照片中还获得了 96 个摄影测量测量值。然后比较了摄影和人体测量测量数据（mm，度）。通过将人体测量测量值除以摄影测量值来获得系数。
标准化摄影的可重复性具有统计学意义（p=0.463）。在 96 个测量项目中，有 44 个项目是可靠的；对于这些项目，摄影测量值与人体测量值没有差异。其余 52 个项目必须归类为不可靠。
通过开发摄影头颅定位器和椅子，我们已经规范了临床摄影技术。可靠的测量项目集可作为人体测量值。对于不可靠的测量项目，将适当的系数应用于摄影测量值可以间接获得人体测量值。
