Application of digital image synthesis technology in fire-fighting and rescue simulation training

Construction and show of fire-fighting and rescue virtual scene is the core of the computer simulation training system. Digital image synthesis technology has a wide range of applications in film, television and other fields. This paper studied how to use digital image synthesis technology to build a virtual disaster scene. It surveyed the creation of scene elements, the synthesis of scene elements and background, the implementation of recycling and the design and implementation of disaster scene model structure. It was achieved through Direct3D and XML technology. Analysis shows: It is feasible and efficient to build real photo and video-based fire-fighting and rescue virtual scene through digital image synthesis technology.
