Description

technical field [0001] The invention relates to the technical field of space target observation, and belongs to optical imaging and image processing technology, in particular to a system and method for observing space targets based on a multi-channel camera. Background technique [0002] In order to achieve large field of view, large aperture, and high resolution optical characteristics measurement of space targets in low and medium orbits and missile reentry imaging, the optical system of the range optical measurement equipment must meet the requirements of large aperture and long focal length at the same time. This will increase the volume and weight of the optical telescope, and in order to ensure the imaging quality, the surface shape accuracy of the large-diameter optical lens is required to be high, so the development cycle of the equipment is long and the investment is large. When the F-number of the telescope remains unchanged, its focal length will become longer wit...

Problems solved by technology

[0004] However, the current multi-channel imaging technology has high requirements for system installation and environment, and is not flexible, and it is difficult to track and record live dynamic targets in the air by using an equatorial tracking system;

[0005] The existing multi-channel imaging system cannot realize the observation of dynamic targets and stars at the same time; and when observing stars, the calculation of the attitude angle of each channel camera is limited to the calibration of the optical axis when observing the same field of view. The optical axis pointing in the field of view observation mode cannot be calibrated

[0006] The current multi-channel imaging technology only uses simple image stitching and energy superposition for post-processing of high-resolution images, which does not give full play to the technical advantages of multi-channel imaging; or too many human factors are added in the high-resolution reconstruction process , the obtained high-resolution reconstructed image may not be the optimal solution

In addition, the devices used need to be independently researched and developed, and their cost is high, which is not conducive to large-scale use
