The invention relates to a dynamic correction method for multi-optical-axis equipment. The method comprises the following steps: establishing a change relation model of a deviation value of a transmitting axis and a receiving axis along with a roll angle; establishing a change relation model of the deviation value of the transmitting axis and the receiving axis along with the pitch angle; 4, performing linear superposition on the two models to obtain a model relationship between the residual deviation of the transmitting axis and the receiving axis and the azimuth pitch angle; and 5, introducing the result into a tracking closed loop, and guiding the target to a calibration position calculated by the model. According to the method, the deviation of the transmitting axis and the receiving axis of the multi-optical-axis equipment under different postures is predicted and solved, and the tracking and aiming precision of the system is improved. 本发明涉及一种多光轴设备的动态修正方法，包括建立发射轴和接收轴的偏差值随滚转角的变化关系模型；建立发射轴和接收轴的偏差值随俯仰角的变化关系
