The invention discloses a centroid calculation method for knife edge method MTF (Modulation Transfer Function) measurement, centroid calculation adopts an iterative Gaussian weighting method, a weighting function adopts a Gaussian function, and the center position and width of the Gaussian function are adaptively changed; the knife edge is a straight line, and when the position of the mass center of the difference image is calculated line by line, the central position and the width of the weighting function after iteration of the previous line serve as the iteration initial value of the next line. According to the method, the iterative weighting method is adopted, the calculation precision of the mass center of the knife edge aberration image can be effectively improved, and therefore the MTF measurement precision is improved; the parameters in the method can be adaptively corrected, and the method can be suitable for MTF measurement of various photoelectric systems to be measured.
