Various studies carried out on different photo anthropometry, but each one had some deficiencies which during the years they have been resolved. The objective of this paper is to test the efficiency of two-dimensional image processing software in photo anthropometry of hand. In this applied research, 204 office workers and industrial workers were selected. Their hands were measured by manual with photo anthropometric methods. In this study, designing the "Hand Photo Anthropometry Set," we tried to fix the angle and distance of the camera in all of the photos. Thus, some of the common mistakes in photo anthropometric method got controlled. The taken photos were analyzed by Digimizer software, version 4.1.1.0 and Digital Caliper (Model: Mitutoyo Corp., Tokyo, Japan) was used via manual method. t-test statistical test on data revealed that there is no significant difference between the manual and photo anthropometric results (P > 0.05) and the correlation coefficients for hand dimensions are similar in both methods illustrated in the range of 0.71-0.95. The statistical analyses showed that photo anthropometry can be replaced with manual methods. Furthermore, it can provide a great help to develop an anthropometric database for work gloves manufacturers. Since the hand anthropometry is a necessary input for tool design, this survey can be used to determine the percentiles of workers' hands.
针对不同的照片人体测量学开展了多项研究，但每项研究都存在一些缺陷，这些缺陷在多年间已得到解决。本文的目的是测试二维图像处理软件在手部照片人体测量中的效率。在这项应用研究中，选取了204名办公室职员和产业工人。他们的手部通过手动和照片人体测量方法进行测量。在本研究中，设计了“手部照片人体测量套件”，我们试图在所有照片中固定相机的角度和距离。因此，照片人体测量方法中的一些常见错误得到了控制。所拍摄的照片由Digimizer软件4.1.1.0版本进行分析，手动方法使用的是数字卡尺（型号：日本东京三丰公司）。对数据进行的t检验统计分析表明，手动测量和照片人体测量结果之间没有显著差异（P>0.05），两种方法中手部尺寸的相关系数相似，范围在0.71 - 0.95之间。统计分析表明，照片人体测量法可以替代手动方法。此外，它可以为工作手套制造商开发人体测量数据库提供很大帮助。由于手部人体测量是工具设计的必要输入，这项调查可用于确定工人手部的百分位数。
