摘要
提出一种小波变换支持的基于灰度和基于特征相结合的分层匹配方案用于DEM自动生成,利用航空与航天影像(MOMS 02,SPOT)进行的试验表明,该方案具有基于灰度、基于特征和分层影像匹配的优点,能以较少的代价获得高精度、高可靠性的匹配结果。
A hierarchical matching algorithm combining grey level and feature based image matching with wavelet transform is presented. Several tests with aerial images and satellite imagery show that the algorithm has advantages of both the grey level and feature based matching and can provide an accurate and reliable result with low cost. The algorithm can be used for automatic generation of DEM.
