Method of DEM Deformation Detection without Control Points Based on Differential Model

  • Received Date: 08 May 2005

  • To improve the performance of the existing deformation detecting algorithms,a novel method based on the differential model was proposed for DEM(digital elevation model) deformation detecting without control points.In addition,it has been successfully used to the deformation detecting of Puwaigou,a debris region with a deformation proportion of over 50%.This method is based on the LZD(least Z-difference) algorithm,as a result,both the magnitude and the relationship of observations can be taken into account by introducing the differential model to greatly improve the ability of deformation detecting.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.
