摘　　要：针对标准投影算法在图像匹配中存在抗噪性差的缺点,文中提出了一种基于提升小波变换与改进空间投影结合的图像匹配算法。首先,通过提升小波变换得到多分辨率图像,对最低分辨率图像应用空间投影算法进行匹配,然后,将得到的粗匹配候选点集应用到高一级分辨率图像的匹配中,最后,应用归一化互相关匹配算法计算最终的精匹配点。仿真结果表明,相比其它的改进算法,该算法的匹配准确度和鲁棒性显著提高。The anti-noise ability is not strong enough for the image matching in standard projection algorithm, so a new algorithm based on both lifting wavelet transform and improved space projection is proposed. First, we get the multi-resolution images by using lifting wavelet transform and make the low-resolution image matchings with space projection algorithm, then apply the obtained roughmatched candidates to higher resolution matching. The precise matching is fulfilled with normalized intensity correlation algorithm. Simulation results show that the algorithm is with high matching accuracy and robustness, being compared with other algorithms.
