摘　　要：对人手的空间运动进行了分析和建模 ,提出了一种利用双信息源进行人手空间定位的新方法 :利用视觉输入提取手的平面位置信息 ,借助安装于肘部的弯曲传感器获取手臂的弯曲角度 ,根据所建模型由二者通过模糊计算确定手的深度信息。通过实验 ,证实了该方法的有效性。In this paper, the 3D space motion of hand was analyzed and the model about it was built. Then, a new method was introduced, which can locate the 3D position of hand by dual information sources: get the plane position by computer vision and get the angle of elbow by sensors. Based on these and the model built, the distance from hand to body can be obtained by fuzzy number computation. The method was confirmed to be feasible by experiments.
