In the imaging process,the image is interfered by the surrounding environment factors,resulting in noise interference.Therefore,a method of digital image displacement calibration based on gray gradient regularization was proposed.The noise of digital image was removed by grayscale gradient regularization.All of the parameters of the camera were calibrated.The displacement calibration method was introduced to calculate the displacement of the measuring point,so as to eliminate the camera lens distortion.Thus,the calibration of digital image displacement was achieved.The simulation was designed to verify the effectiveness of the proposed method.Simulation results show that the proposed method has high displacement detection accuracy,so that the effectiveness of the proposed method can be proved.This method can provide a powerful help for related methods of digital image.
