摘要

摄像机倾斜引起的投影失真给后续的图像处理和模式识别带来了极大的不便。本文提出了一种基于射影几何的红外图像射影畸变校正方法。首先识别畸变图像中包含所有射影校正信息的对偶二次曲线，然后通过对偶二次曲线的分解得到射影变换矩阵。最后进行优化，得到最优结果。实验结果表明，该方法能有效地消除红外图像的投影畸变。

Projective rectification of infrared image based on projective geometry

Projective distortion caused by tilted camera brings great inconvenience to subsequent image processing and pattern recognition. In this paper, a method based on projective geometry is introduced to correct the projective distortion of infrared images. The dual conic in distortion image, which contains all the information of projective rectification, is identified firstly, and then the projective transformation matrix is derived by decomposing the dual conic. Finally, optimization is carried out to get the optimal result. Experimental results show that the method used in this paper can remove the projective distortion of infrared image effectively.
