Method for geological disaster body deformation analysis based on Kriging interpolation algorithm

The invention discloses a geological disaster body deformation analysis method based on a Kriging interpolation algorithm. The method comprises the following steps that topographic data of the same to-be-analyzed area in two different periods are selected, the topographic data of the two different periods are extracted into two sets of scattered point set data, and each set of scattered point set data is divided into three columns which are x coordinates, y coordinates and z coordinates of scattered points; setting a discrete distance d, and performing fixed-distance interpolation on the two groups of dispersed point set data by using a Kriging interpolation algorithm to generate two groups of fixed-distance interpolation point set data; the z coordinates of the two sets of fixed-distance interpolation point set data are differenced, the x coordinates and the y coordinates are kept unchanged, and a set of difference point set data is obtained, namely, the equal-distance scatter point height difference variabl
