Aiming at the high-precision pointing demand of photoelectric guided missile, studies the method of missile target calibration to correct the system error and improve the pointing accuracy of photoelectric seeker. Two calibration methods, analytical method and geometric method, are proposed. Analytical method is based on mathematical derivation, using coordinate equivalent transformation to get equations, and solving multiple equations to obtain correction angle; geometric method is from the perspective of distance approximation, through multi-point measurement of actual pointing error, using least square, geometric rotation transformation and other methods to get the correction angle. In the end, two kinds of target calibration algorithms are simulated by numerical simulation, and the effectiveness of the two algorithms is verified by comparative analysis.
