本文介绍了一种用于校准指甲成像系统的自动化程序,目的是预测指垫力。该系统使用磁悬浮触觉装置对人体指垫施加力,同时记录指甲和周围皮肤的图像。设计了一种新的力控制器,实现了与人体指垫的稳定交互。这些数据被用来校准一个主成分回归模型,该模型将像素强度与三维力联系起来。利用该自动化程序的数据,该模型同时预测三维力,均方根误差为0.56±0.03 N(力全范围的7.7%)。
This paper presents an automated routine for calibrating a fingernail imaging system, with the intent of predicting fingerpad forces. The system uses a magnetic levitation haptic device to apply forces to the human fingerpad while recording images of the nail and surrounding skin. A novel force controller is implemented to interact stably with the human fingerpad. The data are used to calibrate a principal component regression model relating pixel intensity to 3-D force. Using data from this automated routine, this model simultaneously predicts 3-D force with an RMS error of 0.56 ± 0.03 N (7.7% of the full range of forces).
