Abstract
The invention discloses a spectrum acquiring apparatus carried on an ultra-low-attitude unmanned aerial vehicle. The spectrum acquiring apparatus comprises a portable fiber optic spectrometer, an outstretching optical fiber head and an external spectrum acquiring device; and the portable fiber optic spectrometer and the external spectrum acquiring device are connected through the outstretching optical fiber head, and the portable fiber optic spectrometer and the external spectrum acquiring device are fixed on the super-low-altitude unmanned aerial vehicle. The spectrum acquiring apparatus is advantageous in being capable of obtaining spectrum information of crops in an object region remotely, providing spectrum data for crop growth monitoring, and providing analysis data for insect disease diagnoses of the crops. In addition, the spectrum acquiring apparatus is small and portable, is high in adaptability to spectrometers in the prior art, and makes a spectrometer only acquiring spectrums at a near distance have the capability of acquiring the spectrums at a long distance; and furthermore, the spectrum acquiring apparatus can be carried by the unmanned aerial vehicle or an airship to carry out large-scale regional crop growth monitoring.
Description
Technical field
The present invention relates to optical image technology field, specifically relate to a kind of spectrum acquisition device, be equipped on extreme low-altitude unmanned plane.
Background technology
The acquisition of crop growth information and monitoring crops suffer disease and pest situation to be pith in production estimation process always.Classic method is that agricultural planting personnel and field work personnel carry out eye-observation or adopt spectroscopy equipment to gather spectroscopic data that is single or zonule crops, carries out contrasting, analyze and identifying in laboratory again.This method cannot obtain information accurately and reliably: one is rely on the initial symptoms that eye-observation cannot judge disease and pest accurately, has careless omission; Two be the spectroscopy equipment carried can only gather single plant or among a small circle in the spectrum of crop, cannot detect on a large scale, waste time and energy; In addition, existing agriculture spectroscopy equipment is hand-held, gathers and requires apart from short, require high, cannot at a distance or at extreme low-altitude collection spectroscopic data, skyborne unmanned plane can not use existing agriculture spectroscopy equipment.
Summary of the invention
The object of the present invention is to provide a kind of spectrum acquisition device, solve problem such as remote or extreme low-altitude remote sensing diagnosis crop pest and remote sensing monitoring crop growthing state etc.
The technical solution realizing the object of the invention is: a kind of spectrum acquisition device, be equipped on extreme low-altitude unmanned plane, comprise portable fiber-optic spectrometer, reach optical fiber head and circumscribed spectrum acquisition device, portable fiber-optic spectrometer is connected by reach optical fiber head with circumscribed spectrum acquisition device, and portable fiber-optic spectrometer and circumscribed spectrum acquisition device are all fixed on extreme low-altitude unmanned plane.
Above-mentioned circumscribed spectrum acquisition device comprises common optical axis and is arranged in order the first imaging len, diaphragm, the second imaging len and fiber optic collimator mirror composition; Reach optical fiber head is positioned at the focus place of fiber optic collimator mirror.
Carry light outgoing after the first imaging len imaging of object images information, after diaphragm, the light of its outgoing enters the second imaging len, after the second imaging len imaging, outgoing is to fiber optic collimator mirror, fiber optic collimator mirror converges after changing light path and is extended formula optical fiber head and receives, and is transmitted through the fiber to portable fiber-optic spectrometer.
Above-mentioned first imaging len radius is greater than the second imaging len.
Above-mentioned diaphragm is positioned at the focus place of the first imaging len, and clear aperature setting range is Φ 1.2mm-Φ 22mm.
The present invention compared with prior art, its remarkable advantage: the spectral information of (1) remote or extreme low-altitude acquisition target area crops, for monitoring crop growth situation provides spectroscopic data, the pest diagnosis that can be crops provides analysis data; (2) small volume and less weight of the present invention, suitability for existing spectrometer is higher, make the spectrometer originally closely gathering spectrum only possess the ability of remote capture, can be mounted on unmanned plane or dirigible, carry out large-scale regional crops growth condition monitoring.
