摘　　要：提出一种便捷的足部参数测量方法,仪器装置成本低廉、操作简洁。该系统利用足底扫描设备扫描足底图像,通过CMOS摄像头获取照射在足面上的结构光图片,运用图像处理技术将足面轮廓点云与足底轮廓点云叠加融合,重构足部三维形状,并据此计算脚型测量的关键特征参数。实验表明,系统能够快速精确地完成三维脚型恢复和足部特征参数的提取,具有很好的鲁棒性。The parameter measurement of the foot is an important part of the human body measurement. Most kinds of the foot measuring instruments have some problems： the prices are very high, the operation is complex, and it is diffi- cult to have a large-scale promotion. In this paper, a convenient method of foot parameter measuring is puts forward, which not only has relatively low cost, but also has simple operation. Combining the image scanning equipment with the scanning images of CMOS camera line structured light, the three-dimensional reconstruction of the whole foot contour is complete by the fusion of the point cloud of the plantar and foot surface using the image processing technology. Then, the foot key characteristic parameters are calculated. The result shows that the system not only can finish foot three- dimensional reconstruction and the extracting of characteristic parameter quickly and exactly, but also has good robust- Hess.
