Photoelectric pod collimation axis error correction method based on integrated navigation post-processing

The invention belongs to the technical field of photoelectric reconnaissance monitoring systems, and particularly relates to a photoelectric pod collimation axis error correction method based on integrated navigation post-processing. The method comprises the following steps: firstly, carrying out a sports car test on the photoelectric pod on the ground; then, the self-collimation work of the optical axis of the photoelectric pod and the collimator is completed in front of the collimator; and finally, carrying out combined navigation post-processing on the synchronously recorded inertial measurement unit data and differential satellite navigation data, calculating course and attitude information of the navigation unit at the moment when the optical axis of the photoelectric pod and the collimator are auto-collimated, calculating a visual axis calibration parameter, and compensating to complete the calibration of the visual axis of the photoelectric pod. The method is different from a flight calibration field m
