Pendulum type spiral scanning imaging system and method for a single small-view-field camera

Abstract

The invention discloses a pendulum type spiral scanning imaging system and method for a single small-view-field camera, relates to an imaging motion mode of a space remote sensing camera, solves the problem that an imaging mode of a traditional camera is small in imaging view field, and realizes large-view-field wide-area imaging under a small load. According to the imaging camera with the small field of view on the imaging load module, large-field-of-view imaging of the imaging camera with the small field of view is achieved through coordinated cooperation of motion and postures of the spatial remote sensing platform, the mechanical rotating module and the swinging device on the imaging load module. Compared with an existing imaging system, the mass and the size of the single imaging loadmodule are very small, and the size and the mass of the remote sensing platform are also smaller than those of the existing remote sensing platform. The contradiction of quality, volume, resolution and breadth of an imaging system of an existing space remote sensing platform and the bottleneck problem of an existing small-field-of-view camera in large-field-of-view imaging application are solved.In the wide-area search, the manufacturing process of the large-view-field camera is complex and difficult, and the structure and manufacturing of the imaging load system are very simple.

Description

technical field [0001] The invention relates to a motion mode of space remote sensing camera imaging, in particular to a pendulum-type spiral scanning imaging system and method for a single small field of view camera. Background technique [0002] The quality, resolution, and width of the optical imaging system in the field of space remote sensing have always been mutually restrictive and cannot be perfected together. In the past research and design ideas, it has always been to achieve high resolution and wide width, so the corresponding quality and volume will be significantly improved, which will lead to an increase in the volume of the remote sensing platform and a reduction in other functions. Nowadays, there are more and more scenes that need to use wide-area search. In the past, large-field-of-view cameras were used to achieve wide-area search, but the manufacture of large-field-of-view cameras is usually very complicated and there are many difficulties. Therefore, it...
