Abstract

The invention discloses a method for correcting a rotary large-breadth optical satellite sensor, which is used for correcting an imaging load carried by a rotary large-breadth optical satellite according to the following method: firstly, constructing a virtual circular large-area array CCD (Charge Coupled Device) according to the imaging load carried by the rotary large-breadth optical satellite;then, creating an original imaging geometric model and an equivalent virtual imaging geometric model, adopting an RFM model for free network adjustment, and space reference unification; and finally, according to the equivalent virtual imaging geometric model and the RFM model of the original imaging geometric model, carrying out virtual resampling based on object space geometric positioning consistency, and a steady-state equivalent central projection sensor correction image is obtained.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a method for correcting a rotating large-width optical satellite sensor. Background technique [0002] In recent years, with the increasing demand for earth observation, the research and development of remote sensing satellite imaging system has also increased. For remote sensing satellite imaging systems, resolution and width are two extremely important indicators that are difficult to balance. However, the load design of this method is extremely difficult, and it is not conducive to the cost control and miniaturization development of satellites. [0003] In order to deal with this problem and realize large-scale and high-time-efficiency earth observation in a large area, rotational earth imaging has gradually become a new model and has been gradually researched and developed. Among them, the rotating large-width optical satellite is used as a satellite for rotating and ima...
