摘　　要：为了简化人体上肢关节活动度测量过程,提高测量效率和准确度,实现活动度的自动测量,提出一种基于Kinect体感交互技术的测量方法。通过Kinect传感器,捕捉上肢各关节点位置,将关节点数据传至计算机;通过检测上肢体运动平面偏离人体冠状面、矢状面和轴向面的距离,规范上肢的测量动作;自动计算肩、肘等关节各科目的活动度数值,由体感人机交互界面实时反馈测量结果。用该方法对40位受测者分5组(每组8人)进行测量试验,并根据t检验法,得到肩关节外展、内收、屈曲、伸展以及肘关节屈曲科目的 t值,分别为1.53、1.17、1.30、1.58和1.47,均小于2.776,测量结果与期望值无显著差异,表明系统的测量精确度较高。In order to simplify the measurement process of range of motion （ROM） of human upper limbs, to improve measurement efficiency and accuracy, and to realize automatic measurement, a measurement method based on Kinect somatosensory interaction technology was proposed. The data of the upper limb joint positions of the subjects were captured by Kinect sensor and transferred to a computer. Then, the data were used to detect the distance between the motion plan of upper limbs and coronal plane （ or sagittal plane, or axial plane） and to regulate the measurement. The ROM results were obtained automatically. The feedback information of ROM was showed on the somatosensory human machine interface in real time. An experiment was performed on 40 persons who were divided into 5 groups. According to the method of t-test, the ] t] values of shoulder and elbow ROM measurement were 1.53 of shoulder abduction, 1.17 of shoulder adduction, 1.30 of shoulder flexion, 1.58 of shoulder stretch and 1.47 of elbow flexion respectively. All of them were under 2. 776. There were no significant differences in measured data with the expected value, so the measurement accuracy was high.
