Pendulum helical scanning imaging system and method with single small field of view camera

Abstract

The pendulum-type helical scanning imaging system and method of a single small field of view camera involves the imaging motion mode of a space remote sensing camera, overcomes the problem of a small imaging field of view in the imaging mode of a traditional camera, and realizes wide-area imaging with a large field of view under a small load. The small field of view imaging camera on the imaging payload module of the present invention realizes the large field of view imaging of the small field of view imaging camera through the coordination and cooperation of the space remote sensing platform, the mechanical rotation module, and the motion and posture of the swing device on the imaging payload module. Compared with the existing imaging system, the mass and volume of the single imaging load module itself are smaller, and the volume and mass of the remote sensing platform of the present invention are also smaller than the existing remote sensing platform. It solves the contradiction between the quality, volume, resolution and width of the imaging system of the existing aerospace remote sensing platform and the bottleneck problem of the existing small field of view camera in the application of large field of view imaging. In the wide-area search, the manufacturing process of the camera with a large field of view is complicated and difficult, but the structure and manufacture of the imaging loading system of the present invention are quite 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...
