| 摘 要： | 提出了一种基于地形的小波场特征的相关匹配的方法.在小波场的相关匹配技术中,由于小波的垂直分量和水平分量反映了图像的边缘等高频信息,所以分解后的小波特征场相关性小,有比较高的匹配精度;同时,由于数据量压缩,提高了匹配速度,适应于地形匹配的快速实现.

| Abstract: | The terrain matching approachbased on wavelet transform features is presented.The approach is as follows: firstly the terrain is decomposed by the multi-resolution Haar wavelet;Secondly,the correlation matching results are calculated by the decomposed results of HL and LH part respectively;Thirdly,the matching result is fused by the algorithm of Dempster-Shafer.Because the terrain is decomposed by the multi-resolution Haar wavelet,the data is reduced,and the main geometry character of original terrain is preserved.The calculation speed and matching precision of this method is better than the conventional one. |
