Description

Technical Field

[0001] The present invention belongs to the field of full strapdown seeker calibration and relates to a full strapdown laser and television composite seeker calibration method, which can simultaneously and simply and quickly calibrate assembly errors, compensate for angle measurement errors caused by assembly errors, and improve the angle measurement accuracy of the full strapdown laser / TV composite seeker. Background Art

[0002] The instantaneous optical field of view of the full strapdown seeker is large. At the same time, the laser / TV photoelectric detector is fixed to the reference base. Ideally, the horizontal plane where the laser photoelectric detector is located should be at the same level as the O c X c Vertically, the horizontal plane where the TV photoelectric detector is located should be at the same level as O d X d Vertical, O c X c , O d X d and O b X b They should be parallel to each other, as shown in the figure Figure 1 As shown, in the laser detector target surface coordinate system diagram, S1, S2, S3 and S4 are the energies of the laser spot on the laser detector, and O1 is the center of the laser detector target surface; in the TV detector target surface coordinate system diagram, (0, 0) is the coordinate origin, (u0, v0) is the coordinate of the optical axis point, (u1, v1) is the position of the target in the coordinate system; O2 is the optical axis point of the TV detector target surface. In actual engineering applications, due to reasons such as processing and assembly, there will always be situations that are different from the ideal state. The errors mainly include structural errors and optical errors; structural errors mainly include coaxial errors of the laser part and the circuit part, installation errors on the reference seat and installation errors of the photoelectric detector; optical errors mainly include focal length errors, aberration errors and hood errors; and structural errors and optical errors can be compensated by certain calibration methods. In the spatial coordinate system, the above errors are described as the coordinate system O of the TV part of the full strapdown composite seeker c -X c Y c Z c 、Laser part O d -X d Y d Z d With the projectile coordinate system O b -X b Y b Z b The error between .

[0003] To improve angle measurement accuracy and ensure the hit accuracy of ammunition equipped with a fully strapdown composite seeker, errors must be calibrated to improve target angle measurement precision. However, current methods for accurately calibrating assembly errors focus solely on the assembly errors of laser seekers or television seekers, and there is no method that can simultaneously and quickly calibrate the errors of fully strapdown laser / TV composite seekers. Therefore, developing a method that can simultaneously and quickly calibrate fully strapdown laser / TV composite seekers has important engineering application value. Summary of the Invention
