With the development of virtual reality，3D reconstruction based on image has drawn increasing attentions. The biggest merit of it is that the posture and texture information can be directly extracted from images to reconstruct geometric models with photo-reality simply and rapidly. The common method calibrates camera in the first step

the calculates space points position in a world coordinate. This paper shows a brand new method which reconstructs models from two images. Firstly

using properties of vanishing points to calculate the position of camera center in the world coordinate. In addition

according to the geometric restriction of the camera

the model posture and position can be acquired. Finally

we extract and rectify the texture from images. In this approach any extrinsic parameters is not needed. The result of experiments proves that the accuracy of this algorithm

and that it can meet the requirement of common object modeling.
