To select an appropriate algorithm for DEM matching, this paper reviews the development of the two popular 3D surface matching algorithms, least z-difference ( LZD) and iterative closest point ( ICP), and describes their common logical framework.

The research result shows that its matching accuracy is higher than that of the M-LZD ( LZD using M-estimator) and LMS-LZD ( LZD using least-median-of-squares estimator) algorithms.

结果表明，新方法的匹配精度比目前代表性的采用M-估计的LZD算法（M-LZD）和采用最小平方中位数的LZD算法（LMS-LZD）的精度高。

Through analyzing the algorithm principle and the transformation parameters relationship, the author puts forward slope-smoothing technique to strengthen and improve the pull-in range of LZD and the matching automatization degree.
