摘　　要：基于主成分分析法设计了一套能精确寻找穴位的按摩装置,以替代中医按摩师进行风池穴按摩。首先,基于风池穴位于人脑后部中心、距离颈部最低点两侧的距离为手掌4指宽度1/2的特征,应用激光测距传感器、步进电机、直线位移传感器进行人后脑颈部最低点搜索并在后脑特定区域进行三维建模。然后,应用主成分分析法计算建立的三维模型应用风池穴周边点云的曲率及其法向量,得出按摩头的位置和摆角角度。最后,该装置将按摩头以计算的摆角角度移动到对应位置进行按摩。A massage device based on principal component analysis method was designed to accurately locate acupoints,replacing traditional Chinese medicine massage therapists for Fengchi acupoint massage.Firstly,based on the feature that the Fengchi acupoint is located in the center of the posterior part of the human brain and is half the width of the four fingers of the palm on both sides of the lowest point of the neck,laser ranging sensors,stepper motors,and linear displacement sensors are applied to search for the lowest point of the posterior neck of the human brain and perform 3D modeling in a specific area of the posterior brain.Then,the principal component analysis method is applied to calculate the curvature and normal vector of the point cloud around the Fengchi acupoint in the established three-dimensional model,and the position and swing angle of the massage head are obtained.Finally,the device moves the massage head to the corresponding position at the calculated swing angle for massage.
