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

Abstract

The invention discloses a camera system and a control method for time-sharing multi-spectral imaging control of a staring space camera. Four basic imaging modes including single spectral single imaging, single spectral continuous imaging, whole spectral single imaging and whole spectral continuous imaging are set in the staring space camera provided with a variable band light filtering device, so as to cooperate with a satellite platform to realize various kinds of earth observation modes. The variable band light filtering device, a focal plane assembly and a signal processing device of the camera are controlled by using a controller in the camera to implement the four basic imaging modes according to set working procedures. Compared with the prior art, the camera autonomous control ability is high, the control equipment required by the camera system is few, the synchronization precision of mechanism action and imaging control is high, the imaging control modes are concise, flexible and diverse and comprehensive in coverage, the camera system can be matched and combined with the operating modes of the satellite platform simply and reliably to implement various types of earth observation tasks, and the control method can serve as the most fundamental time-sharing multi-spectral imaging control method of a static-orbit staring space camera.

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...
