Camera system and control method for time-sharing multi-spectral imaging control of staring space camera

Abstract

A camera system and control method for time-sharing multi-spectral imaging control of a staring space camera, in which a single-spectrum single imaging, single-spectrum continuous imaging, and full-spectrum imaging are set in a staring space camera with a variable band filter device Four basic imaging modes of single imaging and full-spectrum continuous imaging are used to cooperate with satellite platforms to realize various earth observation modes. A controller is used in the camera to control the variable band filter device, focal plane assembly, and signal processing device of the camera to realize these four basic working modes according to the set workflow. Strong autonomous control capability, less control equipment required by the system, high synchronization precision between mechanism action and imaging control, simple, flexible and diverse imaging control modes, comprehensive coverage, and simple and reliable matching and combination with satellite platform working modes to achieve various types of ground-to-ground Observation tasks can be used as the most basic time-sharing multi-spectral imaging control method for staring space cameras in geostationary orbits.

Description

technical field [0001] The invention relates to a camera system and a control method for time-sharing multispectral imaging control of a staring space camera, belonging to the technical field of spaceflight optical remote sensing. Background technique [0002] Staring space cameras are mostly used for earth observation in geostationary orbit. Because of the wide monitoring range and high time resolution brought by the characteristics of the geostationary orbit, staring cameras in geostationary orbit can be used for disaster reduction, meteorology, earthquake, forestry, ocean, land, and water conservancy. It has become an important direction for the future development of earth observation technology at home and abroad to provide remote sensing data services for applications in many industries. [0003] Earth observation satellites in geostationary orbit have the characteristics of multi-user, multi-purpose, and multi-tasking in parallel. According to different observation tas...
