The paper achieves similar deformation easurement of material model based on digital measurement methods for close-range photogrammetry.It contained the model reconstruction in different periods being achieved with common non-metric digital camera for image data acquisition and adopted such steps as in-situ plane camera calibration and feature extraction.Model deformation can came out of calculation through comparing with feature point coordinates in different periods,so as to carry out mining subsidence prediction.Through comparing with deformation measurement by the total station method,the corresponding results demonstrate the effectiveness of the above method.
