摘　　要：针对现存的虚拟装配系统交互的沉浸感和适应性不强等缺点,采用一对正交放置的光学摄像机,首先从二值图像中提取双手轮廓,自动跟踪双手的运动轨迹,同时利用手势轮廓的Hu矩特征进行手势识别,分离出左右手的移动向量,根据物体的轴向包围盒进行碰撞检测,实现了一个可以用双手与计算机进行交互的虚拟装配系统,验证了方法的可行性。To solve the problem of the existing virtual assembly system＇s bad immersion and interaction, a pair of optical camera arranged orthogonally is used. Firstly, the contour of hands is obtained from binary images, and the trajeetories of double hands are tracked automatically, while it used Hu moments of contours to recognize gestures and isolated left and right motion vectors, aeeording to the objects＇ axis-aligned bounding boxes to detect collision, a virtual assembly system is implemented, which users ean use both hands to interact with computer. Finally, the feasibility of the method is verified.
