In traditional augmented reality system, it is difficult to implement the collision interaction between the virtual objects and actual objects. In order to solve the problem, this paper puts forward a method that uses scene range image segmentation and builds proxy geometry for every segmentation result to realize the collision interaction between virtual and actual objects. It adopts 3D depth measuring devices such as Kinect to get the color image information and range image information of current real scenarios. It analyzes the range image and through the way of normal clustering and plane fitting to segment the major plane area and other objects areas. Then, a 3D virtual plane of the identified plane and a 3D bounding box of the segmented object will be built up as the proxy geometries which later will be overlaid on the actual objects and endowed with physical property, thus enabling us to simulate the collision interaction between virtual and actual objects.Experimental results show that the algorithm can segment simple scenes effectively and realize the collision interaction between virtual and actual objects successfully.
