一种基于透视投影的纹理校正方法

A METHOD OF TEXTURE RECTIFICATION BASED ON PERSPECTIVE PROJECTION

论述了一种基于透视投影的纹理校正方法。该方法以立体视觉中的线性摄像机模型为基础 ,针对虚拟场景漫游的特点及需要 ,利用透视投影中点的对应关系 ,通过图像空间与纹理平面上的四点对应 ,求得纹理校正的投影矩阵。还对采用本方法的实验结果进行了讨论。

This paper puts forward a method of texture rectification based on perspective projection. Based on the model of linear camera in the stereovision and the character of wandering in the virtual scene, this method can get a projection matrix by the correspondence of four points between image space and texture plane. At the end of this paper, some experiment results produced by the method of this paper are discussed.
