Abstract

The invention discloses an on-board multi-spectral hyper-spectral earth observation device. A hyper-spectral multi-spectral imaging unit is used for obtaining a ground hyper-spectral multi-spectral image, the position posture information of each frame of image is recorded and stored through second pulse signals sent by an inertial navigation unit to an image storage unit in a time service way, so that the off-line processing of later-period data is convenient; a host computer unit is in charge of the alignment of an inertial measurement unit, the parameter setting and the image collection of a multi-spectral imaging and hyper-spectral imaging unit and the off-line correction work of the image; a vibration reduction unit reduces the influence of vibration on the obtained image. The device provided by the invention overcomes the defects that a traditional device can only use one kind of multi-spectral or hyper-spectral equipment for image information obtaining, and no reference is realized during correction. The device can meet the dynamic monitoring requirements of a plurality of side surfaces including the pasture condition monitoring and change detection, ecological environment and ecological disaster monitoring, digital cities, aquatic environment integration and the like, and can also meet the requirements on ingredient contents, existence state, space distribution and dynamic change of a sample.

Description

technical field [0001] The invention relates to the technical field of hyperspectral remote sensing, in particular to a ship-borne multispectral hyperspectral earth observation device. Background technique [0002] Hyperspectral is a frontier in the development of remote sensing technology and has achieved great success in many fields of application. There are two traditional spectral earth observation devices used on boats: one is composed of a hyperspectral sensor and a pose sensor, and only one hyperspectral camera cooperates with a pose sensor; the other is composed of several multispectral sensors Camera composition. Among them, the form of hyperspectral camera is to record the spatial position of each frame of line scan image in real time, and generate hyperspectral image by using common baseline equation, resampling, adjustment and other steps. The corrected image has less deformation when the flight is very stable. If the local airflow is large during the flight, t...
