摘　　要：为了得到大视角图像较好的拼接效果,本文提出了一种新的图像拼接方法。该方法利用逆透视投影变换的方法解决了大视角图像间视差过大的问题,利用多分辨率匹配来提高图像匹配速度,利用选取特征区域的方法来提高模板匹配的精度。实验证明了该方法能有效解决简单环境下大视角图像的拼接问题。Aimed at getting a better effect of stitching images with big angular field of view, this paper proposed a new image stitching method. In this method, inverse perspective mapping （IPM） was first utilized to solve the problem of too big parallax when stitching two images with big angular field of view. Multi-resolution matching method was then utilized for improving the matching speed. After that, the method of choosing characteristic regions was utilized for improving the matching precision. Experiments show that this method is valid for stitching images with big angular field of view in simple environments.
