Abstract: The paper designed and realized a kind of interaction and demonstrating system based on free-viewpoint stereoscopic video of surface mining virtual reality technology combining with the newest(interactive) free-viewpoint stereoscopic video technology and surface mining virtual reality technology.It(established) virtual visual model of a surface mine using 3DS Max and VRMap software,further more, scene romance and video image creation of such models were carried out in accordance with conditions fit to proper tidimensional display.At last,it designed interactive free-viewpoint stereoscopic video software combining with three-dimensional demonstrating characteristics of virtual scene,by which virtual reality scene was shown.The system overcame localization of traditional virtual reality demonstrations and (entitled) more users to participant in and interact with lower(cost.) The system owned stronger environmental expansion at the same time.
