When roaming in a 3D virtual scene

texture mapping is a main tactic to display the reality of the scene.But for some special cases i.e.the position of the object or other difficulties which can't be overcome

the texture with perspective distortion is got.Here how to rectify the plain texture to remove perspective distortion and corresponding texture mapping are discussed.This process is as follows: applying projective transformation on the plane

using interpolation method to acquired texture

and then mapping it on the model.This is based on reconstruction from two views.Some existing algorithms are used and some changes are made to achieve a good result during projective transformation.Then the result of test is analyzed and discussed.This method can be used to construct a virtual scene

or clarify the blur of the photos for the reason of perspective distortion.
