Description
Technical field
The present invention relates to remote sensing technology field more particularly to a kind of vehicle-mounted 360 degree of panorama target identifications systems based on spectrum
System.
Background technology
The development of remote sensing technology experienced panchromatic (black and white), colored (RGB), after multispectral scanner imaging session, by
In the imaging spectral technology that the phase at the beginning of the eighties in last century occurs, optical remote sensing is promoted to enter a brand-new stage --- bloom
Compose the remote sensing stage.So-called EO-1 hyperion refers to the remote sensing science with high spectral resolution and technology, imaging spectral technology institute
The imaging spectrometer used can be in the ultraviolet of electromagnetic spectrum, visible light, near-infrared and short-wave infrared region, and acquisition is many very
The continuous image data of narrow and spectrum.Imaging spectrometer provides the spectrum letter of tens of to hundreds of narrow-bands for each pixel
Breath constitutes a complete and continuous curve of spectrum therefrom.The various atural objects that imaging spectrometer will be observed in field range
It is recorded with the complete curve of spectrum, and analyzing processing is carried out to recorded data and studies multidisciplinary to be carried out
Work.
The cross discipline emerging as one is related on the basis of primarily resting on the technologies such as sensor, computer
EM theory, spectroscopy and colorimetry, physics/geometric optics, electronic engineering, informatics, geography, agronomy, atmospheric science,
The multi-door subject such as oceanography.And EM theory is then the physical basis of remote sensing technology, the phase interaction of electromagnetic wave and terrestrial materials
With mode in different medium of mechanism, electromagnetic wave and to be received, analyzed to it be comprehensive each door subject and technology
Where core.For the different spectral signatures of different atural objects, atural object can be efficiently differentiated and identified using high spectrum image, be one
The typical untouchable non-destructive testing technology of kind, can obtain the spatially and spectrally information of target, according to " referring to for unlike material simultaneously
Line " spectral signature can realize the work such as the identification of the detection to target.Thus be widely used in Atmospheric Survey, medical diagnosis,
In material classification and target identification, land resources, ecology, environmental monitoring and urban remote sensing, due to the particularity and technology of industry
Using the limitation of means, its remote sensing number is obtained by modes such as satellite remote sensing, Fixed Wing AirVehicle, rotor wing unmanned aerial vehicles mostly
According to.
Currently, there are two types of common target identification systems.One is sweeping type imaging spectral camera system to pushing away, such as Fig. 1 and
Shown in Fig. 2, the system include imaging lens 19, high imaging spectrometer 20, planar array detector 21, two-dimension translational sweep mechanism 22 with
And package casing (package casing is not drawn into), by high imaging spectrometer and planar array detector be fixed on two-dimension translational sweep mechanism it
On, imaging lens are fixed on package casing, and high imaging spectrometer and planar array detector are combined, and with imaging lens with
Separate.In imaging process, two-dimension translational mechanism can drive the one-dimensional sky of high imaging spectrometer and planar array detector wherein
Between it is upper move (in moving sweep dimension), push away the type imaging pattern of sweeping and be also all merely able to that a line on target object is presented every time,
The splicing of image is completed by the relative motion of object or imaging mechanism.So the slit of high imaging spectrometer can with it is poly-
The minute surface keeping parallelism of zoom lens, imaging lens can with driven in translation mechanism under the optical spectrum imagers and planar array detector that move
There are an opposite movement, this process namely to push away the process for sweeping type high light spectrum image-forming.The high imaging spectrometer energy of the system
The consecutive image of wave bands up to a hundred is accessed, and each image picture elements can extract a curve of spectrum.Traditional two dimension at
As technology and spectral technique combine, while obtaining measured object spatial information with imaging system, pass through light
Spectrometer system radiates the RADIATION DECOMPOSITION of measured object at the spectrum of different wave length, and it is several to obtain each pixel in a spectrum range
Ten or even hundreds of continuous narrow-band information.Its wave band is not discrete and is continuous, therefore can be from its each picture
Member can extract a smooth and complete curve of spectrum.And each pixel includes the spectrum letter of target object simultaneously
Breath and radiation information.Therefore, the advantage of the system is：The very high-resolution spectral information of target can be obtained, to target
There is very big help on discrimination precision, and spectral region is also wider, from visible light to short-wave infrared, medium-wave infrared all may be used
To apply (350nm~4000nm).Scanning shift mechanism has very high precision to ensure image quality.And the disadvantage of the system
For：Since push-scanning image needs the mobile of sweep mechanism that could realize that the stroke of scanning is also very limited, and spatial resolution is low,
Because the pixel of planar array detector used in current push-scanning image is
1936x1456 (Spatial Dimension x spectral Dimensions), can reach 2048x2048, even now with many camera pixels
Higher, but pixel improves, and the technology needed requires also very high；Also, allow to realize that the structure of 360 ° of rotations is auxiliary
It is helped to be implemented as picture, data volume is also very big, 360 degree rotation scanning, that is, mutually confidential is stored to each row information
And calculation processing, it is 380KB according to data line amount size
(969x256, Spatial Dimension x spectral Dimensions), 360 degree of one week data volumes of scanning are：
380Kbx10000=(3800000Kb/1024) M=3800M=3.8G, it can be seen that in terms of handling timeliness
It will reduce.
Another kind is LCTF type multi-spectral imagers, it includes camera lens 23, LCTF24 and planar array detector 25；Such as Fig. 6 institutes
Show, principle is：Multiband spectrum tuning is completed by LCTF, is on the one hand because LCTF is in very wide spectral region using LCTF
Inside there is very high transmitance, is on the other hand because it has very high photoelectric action coefficient.LCTF is the interference based on polarised light
Principle and be made, be a kind of Lyot types tunable birefringent filter part, formed by arranged in parallel multi-stage cascade of being permitted successively, often
Level-one includes that there are two the polarizing film being mutually parallel, sandwich liquid crystal retardation pieces.When light source is by wherein primary unit, by
It is identical in the two-beam direction of vibration that fast, slow axis is propagated along liquid crystal, and position difference is certain, therefore interfere effect.Light source is sent out
The light gone out, which is radiated at, to be taken in target, and a part of light reflection is utilized the recordable lower target of multi-spectral imager by target surface
Single wavelength two dimensional image, by adjust LCTF penetrate wavelength, a series of monochrome image of different wave lengths can be obtained, by these
Monochrome two-dimensional image is rearranged three-dimensional multispectral image cube by wavelength order.Connection type that there are two types of this systems,
It is respectively：As shown in figure 3, LCTF, camera lens and planar array detector are sequentially connected；As shown in figure 4, camera lens, LCTF knead dough battle arrays detect
Device is sequentially connected；The shortcomings that first method is：Since LCTF has certain thickness, when the clear aperture of camera lens is more than the hole of LCTF
Optical energy loss is had when diameter and generates vignetting, and the weight of LCTF can also influence the design of imaging system, to ensure that light path is coaxial, need
Supporting mechanism is added to LCTF.The shortcomings that second way is：Since the camera lens of commercialization is connected directly according to camera
Situation design, after addition has certain thickness LCTF between camera lens and camera, image can be made to generate distortion, aberration etc., and
The scale value of the magnifying power of change system, camera lens will be no longer accurate etc..Also, LCTF type multi-spectral imagers are although spectrally resolved
Rate is higher, but image resolution ratio is poor.
