一种消除图像射影失真的实用方法

本文介绍一种实用的消除图像射影失真的方法。首先，从射影几何的角度出发，介绍了2D射影矩阵，给出求解该矩阵的求精算法；其次，在已知2D射影矩阵的情况下，介绍了消除射影失真，恢复物体真实几何形状的方法；最后，利用上述方法对真实图像进行了恢复实验。这种方法不需要事先标定摄像机，经实验表明，处理简单，效果理想，实用性强，可以应用于测量、公安等各个领域。

A Pratical Method of Removing the Projective Distortion

This paper introduces a practical method which can remove the projective distortion from an image of a plane. First, we inducted the homogeneous matrix using projective geometry,and derived the appropriate algorithms to solve this matrix. Then we introduced a method which can eliminate the distortion and rectify ( or warp) the image.At last, we used some images of real objects and displayed the results of our experiments.The experiments indicated that the result was very successful.
