Virtual reality, a virtual world generated by computers, can give us a variety of sensory stimulation and a sense of immersion, and also be navigated in it and manipulated with it interactively. With the development of modern technology, the system now can provide several sensations including sight, hearing, touch, smell. According to the physiological characteristics of human beings, the information human obtained from the objective world are 70% -80% more from vision, therefore, scene simulation becomes the critical technology in building a VR system.Hence, the scene simulation technology is mainly discussed in this paper, including graphics-based rendering and image-based rendering ( IBR ) technologies, with the main technology discussed in the IBR panoramic image. Panoramic image formation needs registration between images, and the method of mathematical morphology is introduced to do image registration, and then a series of images examples are given to demonstrate the feasibility of the method. |
