Description
Technical field
The present invention relates to a kind of adapting to image information acquisition system and method for work, particularly relate to a kind of imitative squill
Compound eye adapting to image information acquisition system and method for work.
Background technology
In the prior art, by DMD, scene image is sampled, due to light intensity change directly
Affect image quality, thus there will be light strong time, definition is high, and when light is weak, definition reduces, and noise increases；Although having
A lot of software processing methods improve the definition under decreased light, but treatment effect is the best, such as, nearest-neighbor interpolation method,
Bilinear interpolation method, bi-cubic interpolation method etc..Bilinear interpolation method has higher heavy than nearest-neighbor interpolation method
Structure accuracy, more preferably, but image there will be sawtooth and blooming to image recovery effects.Although the reconstruct of bi-cubic interpolation method
Effect is better than the above two, but with sacrifice efficiency as cost, its spent time is several times even tens times of other method.With
Time these algorithms only consider the dependency of local pixel and the overall situation, have certain effect in image recovery effects improving, but but
Destroy the high frequency detail of original image.
Now studies have found that, insecticide has more broad living environment, and such as, the waters that squill is lived is under water
50 meters extend to 100 meters under water.In this context, due to solar irradiation and the common effect of aqueous medium, its illumination condition
Producing violent change, in order to adapt to this changeable living environment, these species are on the premise of ommatidium arrangement architecture is fixing, logical
Cross the common effect of crystalline lens, rhabdom, the size of adaptive regulation light acceptance angle, formed not in the ken of whole compound eye
With the overlap of degree, finally receive the optical information of different qualities according to different light environments.In bright and darkness two kinds
Under illumination condition, squill is by the lax of myofilament and tightens regulation crystalline lens and the length of rhabdom, thus realizes ommatidium and regard
The effect that territory reduces or expands, obtains metastable photon numbers or preferable spatial resolution, makes the two reach balance.Root
According to acquired results in laboratory conditions, squill is under different illumination intensity environment, and the imaging of its compound eye is gone extensive angle and regards
Territory can occur respective change, as under brightness adaptation, its ommatidium ken is 5 degree, is under corresponding dark adaptation 2.5 times of 2 degree of ommatidium kens.
The imaging control mechanism of this Compound Eye of Insects can be according to the scope changing the regulation ken of environment illumination intensity, if by this
Bionics principle is applied in image sampling process, and the imaging effect of sampled images will be greatly improved.
