Description
The invention belongs to the image-processing system that soot-and-whitewash is carried out pseudocolor encoding.
People's eyes are resolving devices of a complexity, though it can only differentiate more than ten gray shade scale usually, but can differentiate the different color of kind more than 100, therefore, can improve human recognition capability greatly pictorial detail by the method for soot-and-whitewash virtual-colorizing technique.
As far back as 1896, Rheinberg just used the wave filter of pseudocolor encoding in microscope, in 90 years thereafter, also had many articles to do to introduce with regard to the optical means of various pseudocolor encodings in succession.F.T.S.Yu once made comparatively detailed summary to this in the book that he publishes nineteen eighty-three.
For the black and white picture of three different-wavebands of same atural object that artificial satellite is taken with multispectral scanner synthesizes a false colour picture, beautiful, day, in three states (China is developed respectively by Changchun ray machine institute and East China Normal University) produced false colour compositor respectively, the method that is adopted is to use one or three arbitrary sources and three projection lens, and then is synthesized.This method is complex structure not only, need be air-cooled, and the cost costliness, and also basic point is: because three passages have three independently optical axises, is difficult for the image of three passages is overlapped.Another shortcoming of this false color compositing technique is, do not possess the function of making fourier transform, therefore can't do spatial frequency and encode and improve the sharpness of image edge and details.
1981-1982, Zhang Youwen once were engaged in the research with grating bleaching coding during U.S. University of Pennsylvania (Pennsylvania State University) does the visiting scholar.Afterwards, raster method at first became grating bleaching compiling method at Chinese development, as the pseudocolor encoding of density of image.Made instrument by this principle Sichuan University, yet owing to have only a passage, it is synthetic to make multiband, also can't carries out the spatial frequency coding.
Hu Guohua in 1984 once designed and had produced a kind of fourier transform instrument.Though this instrument can be made spatial frequency coding, yet, therefore need add mask to low-pass filtering, high-pass filtering and three processes that do not add filtering respectively color negative film is exposed also owing to have only single passage.Like this, complicated operation not only, and owing to be not real-time processing, the image in the time of both can't guaranteeing at every turn to handle on the color negative film can not blur because of moving, whether can not know for sure the colour and the time of exposing suitable at every turn.In addition, this instrument yet has only function of single channel fourier transform, and it is synthetic to make hyperchannel.
The present invention can overcome the shortcoming of above-mentioned prior art, its characteristics are by using three can carry out the synthetic passage of fourier transform or multiband simultaneously, in the system that has only a light source, an optical axis and a fourier transform immaging lens, be implemented on the amplifying screen image of three passages is aimed in real time, Real Time Observation, and the colour and the light intensity of each passage adjusted in real time, once photo taking success then, thus make image quality obviously improve.We have retrieved a large amount of foreign patents, all do not find and same Patent of the present invention.
The light schematic diagram of the real-time pseudo-color coding system of five functions such as Fig. 1 represents to have simultaneously that multiband is synthetic, density coding and spatial frequency coding.
The light schematic diagram of Fig. 2 representation space frequency coding and grating bleaching coded system.
Basic principle of the present invention is referring to accompanying drawing 1.
The light that sends from polychrome pointolite S is through collimation lens L
1Be collimated into directional light, be mapped to color separation film F
1On, this color separation film is that a cutoff wavelength is the back cutoff filter of 0.63 μ ± 0.01 μ, its transmission indigo plant, green glow reflect red.The indigo plant that sees through, green glow are mapped to second color separation film F
2On, it is that a cutoff wavelength is the back cutoff filter of 0.51 μ ± 0.01 μ, saturating indigo plant is anti-green.The green glow of reflection is mapped to the 3rd color separation film F
3On, it is the preceding cutoff filter of cutoff wavelength 0.56 μ ± 0.01 μ, its reflect green light also sees through from F
1Reflection is again through mirror M
1The ruddiness of reflection.These green glows and ruddiness are mapped to the 4th color separation film F
4On, it is that a cutoff wavelength is the preceding cutoff filter of 0.48 μ ± 0.01 μ, it sees through green glow and ruddiness, and reflection is from F
2See through and through M
2The blue light of reflection is like this through F
4What obtain is red, green, blue three coloured light.In like manner, as required if with different color filters, just can tell the light of other color.
The dotted portion representation space frequency coding among Fig. 1 and the principle of work of grating bleach density coding system.At this moment, at F
1Negative film (thing sheet) P is inserted in appropriate location in the parallel light path before (make and satisfy imaging on B ')
iWith lens L
2, by L
2To P
iCarry out fourier transform, make and on the focus of three passages, all obtain its frequency spectrum, on the focus of (1) passage, add respectively then and put Hi-pass filter T
h, add low-pass filter T on the focus of (3) passage
1, make background with image on (2) passage and do not suffer a loss (on the figure with T to keep visual original resolution
oExpression does not add wave filter).Like this, remove L
3, just can be on B ' (B ' position need do suitably to move) colour of obtaining a spatial frequency coding resemble, wherein Tu Xiang HFS (image edge and details) be red, low frequency part (visual flat) is a blueness, background then is a green.On the layout of light path, also can suitably select P
iThe position of selecting makes P
iPass through L
2Imaging is at P
