Tower foundation stability analyzing method based on three-dimensional deformation monitoring of unfavorable geologic body of power grid

The invention discloses a tower foundation stability analyzing method based on three-dimensional deformation monitoring of an unfavorable geologic body of a power grid. The method mainly comprises the following steps of selecting a multi-platform multi-time-domain high-resolution SAR image which satisfies a requirement; extracting deformation estimation of the unfavorable geologic body in a single-platform high-resolution SAR image by means of PS-InSAR technology; based on the deformation estimation of the unfavorable geologic body in the single-platform high-resolution SAR image, estimating the three-dimensional deformation of the unfavorable geologic body of the power grid by means of Kalman filtering technology; and detecting a power transmission tower in the high-resolution SAR image based on a TurboPixels multidimensional dividing algorithm and automatically analyzing the tower foundation stability of the power transmission tower. The tower foundation stability analyzing method overcomes defects of time-and-labor wasting and incapability of obtaining deformation of a whole area in the three-dimensional deformation acquiring method of the unfavorable geologic body in the existing power grid. A tower foundation stability result can be conveniently and quickly acquired.
