description The invention relates to an OIS anti-shake performance test method and device based on curve fitting, and the method comprises the steps: enabling a camera to carry out the image collection of a target plate in a static state, a vibration state when an anti-shake function is turned off, and a vibration state when the anti-shake function is turned on; acquiring a plurality of pieces of first image information, second image information and third image information; respectively determining the central position of the standard graph in each piece of image information, fitting to obtain a static curve, a vibration curve and an anti-shake curve, and calculating the fluctuation amplitude of the curves; and calculating the anti-shake suppression ratio of the camera OIS according to the fluctuation amplitude of the curve. According to the method, the fluctuation amplitude of the center position of the standard graph in each state is obtained through curve fitting, and then the inhibition ratio of camera OIS anti-shake
