This paper proposes a new method to simulate continuous image transitions of a three dimensional scene under perspective projection. With very limited information about two 3D reference planes and two perspectively projected images from two different viewpoints, continuous image sequences which are geometrically correct can be generated by using some view invariants of perspective projection. This method, compared with model-based algorithms, eliminates most of 3D computations such as coordinate transformations and decreases storage requirements for 3D data of object models. In addition, it has better precision than that in image-based frameworks due to the use of the view invariants. Based on the assumption that there are at least five reference points of the reference plane on which objects are placed can be identified in two corresponding 2D images, and any three of them can not be collinear, images of objects can be synthesized via locating image features on projections of reference plane using the view invariant cross ratios. In this paper, we will focus on the simulation of perspective transition images of object edges due to a linear motion of viewpoint. Error Analysis for the image synthesis due to errors in feature extraction, etc., will also be provided.
