Abstract

We propose a more exact model for the study of the visual image of the moving object by considering
a pinhole imaging process on the base of the point observed model. We derive the exact theory formulas for the
calculations. Considering the cube for instance，we show the visual images of it with low and high speeds on one
observed direction. The edge of cube with high speed will be bent in the visual image. The difference between the
cases of closing to observer and away from the observer is discussed.

Key words： special relativity; Lorentz contraction; visual image
