Physiological phenomenon, it is balanced action of the retina to color.Refer on hue circle angle (including 120 ° between 120 ° to 240 °
With 240 °) two groups of colors.Contrastive colours are put together, striking contrast difference sense can be given people.And it is right to contrast most strong two kinds
Colorimetric is complementary colours, i.e., the color of each color opposite (with substantially 180 ° of the color angle) on hue circle.It is big herein
Cause as 180 °, it is 180 ° of ± predetermined deviation angles to refer to angle, because, in hue circle, a kind of distribution of color is past
Toward occupying one piece of region in hue circle, rather than a range of linearity, this predetermined deviation angle with hue circle color category number not
Change together.For example, in the case of 16 hue circles, each color occupies about 22.5 °, then will can preset based on experience value inclined
Declinate degree is arranged to 15 °, i.e. angle is 180 ° ± 15 °, predetermined deviation angle further can also be increased or be reduced, with adjustment
The precision of color selection, is belonged within protection scope of the present invention.
As shown in figure 3, being a kind of schematic diagram of 16 hue circle, wherein α is 120 °.Wherein n1~n16It can represent red respectively
Color, orange red, orange, orange-yellow, yellow, bluish yellow color, yellow green, leaf green, green, blue-green, blueness, ultramarine blueness, ultramarine
Color, livid purple color, pansy and aubergine.Assuming that background color is n5Yellow, then its complementary colours is n13Ultra marine blue, i.e. perspective view
When the color of picture is ultra marine blue, the contrast with background color is most strong, can give user most strong distinguishing.In addition, perspective view
The color of picture can also select the complementary colours of yellow, i.e. n11Blueness, n12Ultramarine blueness, n13Ultra marine blue, n14Livid purple color and n15It is purple
Any one in rowland color.16 hue circles shown in Fig. 3 are only a kind of example, in actual applications, can also be according to need
Increase or decrease the quantity of color in hue circle.And when including multiple elements in projected image, such as in projected image
Comprising figure, word, mark etc., the contrastive colours of a variety of background colors can be respectively adopted.
When determining the color of projected image according to the background color of the predeterminable area, following steps can be used：
The RGB of the projected background color of the predeterminable area is determined according to the reflective spectral property of the predeterminable area first
Value；
According to the rgb value of a variety of colors in hue circle, determine the rgb value of projected background color of the predeterminable area in color
Position in phase ring；
The contrastive colours that the projected background color of the predeterminable area is selected from the hue circle are the projected image
Color；
According to the rgb value of the contrastive colours of the projected background color of the predeterminable area, the color of the projected image is determined
Rgb value.
For example, when the background of predeterminable area is yellow, predeterminable area is determined according to the image information of visible ray first
The rgb value of projected background color be located at the rgb value tolerance corresponding to yellow within the scope of (due to background color not necessarily with
The RGB color of a variety of colors described in color and intensity proportion unit is completely the same, it is allowed to exists a certain degree of trickle inclined
Difference).For example, yellow rgb value is R=255, G=255, B=0；And the rgb value for working as background color is R=250, G=250, B=
When 5, it is also assumed that it is yellow, n is classified to5Within the scope of.Select face of the contrastive colours of yellow as projected image
Color.Such as select n11Color of the blueness as projected image, blue rgb value are R=0, G=0, B=255, so that it is determined that
The rgb value of projected image is R=0, G=0, B=255.
After the rgb value that projected image is determined, projecting subassembly is schemed after composite projection's image is obtained according to composite projection
The visible ray that the rgb value modulation of picture is injected, so as to realize composite projection's image projection by blueness into predeterminable area.
In some application practices, predeterminable area not only has color background, and the color background also has the difference of light and shade,
I.e. the color saturation of the color background may be affected by other factors and be varied from, such as the white light in ambient light can significantly drop
The color saturation of low projection surface, when being projected in skin surface, skin can also contain certain black content.In such case
Under, in order to show the maximum projected image of contrast, when selecting the color of projected image, it is also necessary to select perspective view
The contrast of picture.
As shown in figure 4, the color and intensity proportion unit determine the projection according to the image information of the visible ray
The color saturation of background, and according to the color saturation of the color saturation of the projected background selection projected image.Alternatively,
The color saturation of each color is divided into m grade by color and the intensity proportion unit, and m is the integer more than 1, the projection
The color saturation grade of image is equal to m+1 with the color saturation grade sum of the projected background.
For example, figure 4 illustrates hue circle in, color saturation is schematically simply divided into 5 grades, yellow class
3rd rank Y of row3Color saturation be 100%, towards center position, Y2And Y1White content it is more and more, colour saturation
Degree is reduced successively, along radioactive ray to external expansion, Y4And Y5Black content it is more and more, its color saturation is also constantly declining.
Similarly, the 3rd rank U of ultramarine color system3Color saturation be 100%, towards center position, U2And U1White content
More and more, color saturation is reduced successively, along radioactive ray to external expansion, U4And U5Black content it is more and more, its colour saturation
Degree is also constantly declining.Black pattern in white background, or white pattern on a dark background when, contrast that human eye is felt
Degree is maximum.Accordingly, it is considered to when arriving light and dark color, scheme of colour of the invention is that bright color and dark complementary color are made into one
It is right.That is U1-Y5, U2-Y4, U3-Y3, U4-Y2, U5-Y1.Pairing in Fig. 4 is merely illustrative, in actual applications, can be as needed
Increase the number of grade, such as be divided into more grades to improve specific aim of color saturation selection etc., belong to the present invention's
Within protection domain.
In addition, according to the observation of a large amount of actual pictures and compare, the contrast of yellow pattern or word in white background
Can be poor.So it should avoid as far as possible on the color background compared with thin shade, the pattern of projection yellow tone series.So
In the tone proportioning of complementary color above, U1-Y5Combination can be changed to U1-R3、U1-B3、U1-G3Any of, also
To say the color replaced with the pure color of Red Green Blue and have Yellow series, same method be also applied for with ultra marine blue face
The light color of those adjacent colors of form and aspect is adjusted to the situation of background.In addition, it is only a kind of citing herein, in practice, it is also possible to deposit
In some other default replaced color, i.e. the known contrast using this kind of color in the background with its complementary colours is not high, can
At least one of three primary colors are changed to so that this is preset into replaced color.
As shown in figure 5, for the shooting of the embodiment of the present invention and projection arrangement are applied to the IMAQ of the back of the hand blood vessel and
Schematic diagram during projection.Using the device of the present invention, it mainly make use of hemoglobin in blood vessel micro- to 1000 to 760 microns of wavelength
The different principle of the absorptivity and surrounding of infrared light other tissues of rice, passes through the near red of camera assembly collection blood vessel first
Outer image, then by projecting subassembly by veins beneath the skin Projection Display in skin surface.When the first kind wave-length coverage light is
Visible ray, when the second class wave-length coverage light is infrared light, by veins beneath the skin is surrounded by subcutaneous fat and musculature, they
There is obvious scattering process for infrared light.Skin histology, hair and the hair follicle of human body all can have absorption to the infrared light of incidence
And scattering process.They have seriously obscured the infrared image of camera assembly acquisition.This technical birth defect is straight in imaging
It is particularly acute in terms of the less fine vascular in footpath.Because blood vessel is more tiny, the endovascular blood volume of unit length is also got over
Few, contained aerobic hemoglobin and the quantity of anaerobic hemoglobin are also fewer, so as to their absorptions to infrared light
It is fewer.Under equal veiling glare background, the contrast of blood vessel and surrounding tissue is just very faint so that even across calculating
Still it is difficult to recognize after machine enhancing contrast.
Based on this, the present invention adds a step computation processor component to blood after the near-infrared image of blood vessel is collected
The step of pipe is tinted.The visible images and infrared image of predeterminable area 61, place are collected using camera assembly first
Reason device can obtain the reflective spectral property of predeterminable area 61 according to visible images, and further obtain the color of projected background
And intensity, the morphological parameters of blood vessel can be obtained according to infrared image, when selecting to project according to the above method color of blood vessel and
Intensity, blood vessel or circumvascular tissue are tinted, the blood-vessel image that this virtual color is tinted is projected into human body
On skin, human eye identification and the difference degree of maximum can be obtained.Because infrared light is typically only capable to obtain subcutaneous shallower venous blood
The image of pipe, therefore the vein blood vessel image 62 that projection obtains is schematically illustrated in Fig. 5.For example, the color of the back of the hand is Huang
Color, the i.e. background color of predeterminable area 61 are yellow, and ultra marine blue or livid purple color can be painted by projecting the image of vein blood vessel, in Huang
Under the setting off of color background colour, it appears it is especially obvious, it is convenient the back of the hand is carried out with blood vessel about or exclusion blood vessel various operations.
In projected image, except blood vessel in itself in addition to, can also include projection relevant information, project relevant information herein
Exemplary word or complementary icon etc. can be included, word or complementary icon can be right using other of yellow background color
Colorimetric, there is certain difference with the color with blood vessel in itself, and it is also more obvious under yellow background color.
As shown in fig. 6, the color due to the back of the hand in itself has certain inhomogeneity, in order to further protrude the position of blood vessel
Put, a monochromatic projected background, the outer wheels of projected background can be projected out to predeterminable area 61 using projecting subassembly first
Exterior feature can be the shapes such as rectangle or circle.When camera assembly gathers the visible light image information of predeterminable area 61 again, acquisition
It is the comprehensive function that ambient light and the projected background project to the monochromatic light of the predeterminable area 61 and the reflectance spectrum of skin surface
As a result.The background color for the predeterminable area 61 for according to this visible light image information determining that there is projected background again, select perspective view
The color of picture and after being tinted to blood vessel, then the blood-vessel image of synthesis is projected on human body skin.
As described above, infrared light can not penetrate beyond the arteries of 10mm hypodermis arrival higher depth, so adopting
It is typically only capable to obtain the image of subcutaneous shallower vein blood vessel with infrared photography.And it is to use X ray to use Angiography
Projection imaging, then can obtain the pictures rich in detail of all blood vessels.Therefore, the second class wave-length coverage light can also be X
Ray.
As shown in fig. 7, it is the schematic diagram of the vessel projection image obtained using X ray as the second class wave-length coverage light.
In the application, projecting subassembly includes an independent x-ray radiation source, and camera assembly is also taken the photograph including a corresponding independent X
As device, need to project X ray to the predeterminable area using independent x-ray radiation source first in projection stage, and use
Independent X ray image pick-up device collection penetrates the radioscopic image of the predeterminable area.It can be obtained simultaneously according to radioscopic image information
To vein blood vessel and arterial vascular form, then by projecting subassembly will project vein image 62 and projection arterial images 63 with
Visible ray form is projected to the predeterminable area 61 in the back of the hand portion.According to the convention of medical science, artery can be contaminated in projected image
Into red, vein dyes blueness.Further, in order to cause artery and vein in projection with higher contrast,
Both colors can be selected according to the background color of predeterminable area.Preferably so that the color of projection vein image 62, projection
