Abstract: In this paper, three key techniques are discussed in building VR visual field based on real images. They are interpolation, registration, and panorama of uncalibrated rotating image sequence. The merits of their implemented methods include the following, （1）The interpolated （registration） image accords with perspective geometry. This one ensures that the interpolated （registration） image is real; （2）When the coefficient（ α ） is changed, the interpolated （registration） images corresponding to different views can be obtained. It means that the view direction can be controlled;（3）The tac\|point cumulation method of panoramic images overcomes some drawbacks in the previous methods; （4）The camera needn’t be calibrated. The experiment indicates that the effect is very ideal.
