Specific embodiment
It should be noted that in the absence of conflict, the feature in embodiment and embodiment in the invention can
To be combined with each other.In the description of the invention, unless otherwise indicated, the meaning of " plurality " is two or more.
The present invention will be described in detail below with reference to the accompanying drawings and embodiments creates.
As shown in Figure 1, a kind of multidimensional camera system of three light fusion, including camera lens 2, active infrared lamp 1, colour
Imaging sensor 4, near-infrared image sensor 5, far infrared imaging sensor 6, microprocessor 7 and image display.
Spectral module 3 in camera lens 2, it will be seen that light, near infrared light, far red light are separated, and are respectively transmitted
Into 6 three color image sensor 4, infrared image sensor 5 and far infrared imaging sensor channels.Spectral module mainly has
Three bandpass filters respectively allow for through wave-length coverage being 400-680nm, three 820nm to 1000nm, 8um to 14um waves
Section.
The color image sensor 4 can theoretically acquire all visible lights in natural environment, generally, it is seen that light
Wave-length coverage be 380-760nm, mainly choose this wave band of 400nm-680nm in actual design；Because visible light 95%
Energy all concentrates on this.In the environment of low-light (level), the brightness of image that color image sensor 4 obtains is lower, and details is poor, but color
Multimedia message has been substantially achieved reservation.At this moment, the key message of acquisition is exactly color, therefore the light that color image sensor 4 acquires
The image information of source and formation is then the image for including color information.
Near-infrared image sensor 5 acquires the infrared light of 850nm active infrared array lamp 1.This light source is video camera system
What system carried, reflected light is generated by being actively incident upon body surface, the brightness of image is obtained, passes through near-infrared image sensor
5 processing generate near-infrared image signal, this near-infrared image signal is usually black and white.The infrared light for choosing 850nm, is to examine
Consider under low-light (level) environment, it is seen that light energy is seldom, and the brightness that corresponding color image sensor 4 obtains is just few, at this moment leads to
It crosses and projects powerful infrared light and can obtain higher brightness of image.In addition, near-infrared image sensor 5 is in 850nm wavelength
On collecting efficiency can accomplish 40%, double than the infrared light collecting efficiency 20% of 940nm, it is clear that choose the wave of 850nm
Length can be more advantageous.
Far infrared imaging sensor 6 acquires the infrared emanation of the 8-14um in environment.All temperature are greater than absolute zero
Object can infrared radiation, and the function of the far infrared imaging sensor 6 exactly converts sightless infra-red radiation to
Visual image with temperature data, it is main to acquire 8-14um in wave-length coverage.The general depth mark for using different colours and color
Know different temperature.
Later, by microprocessor 7, by the color image signal on color image sensor 4 and on near-infrared image 5
Picture signal synthesize nature rgb image, it is that one kind is extracted color that software process quality algorithm, which turns HSV space model using RGB,
With the algorithm of brightness rear weight.The weighting algorithm that specific RGB turns in HSV space model is as follows:
V=max
Max is set from RGB to HSV equal to the maximum in r, g and b, min is reckling；In corresponding HSV space (h,
S, v) value, as r=h, g=s, b=v.
Wherein: tone (H, Hue), saturation degree (S, Saturation), lightness (V, Value)；
Tone H is measured with angle, and value range is 0 °~360 °, is calculated counterclockwise since red, red is
0 °, green is 120 °, and blue is 240 °.Their complementary color is: yellow is 60 °, and cyan is 180 °, and magenta is 300 °；
Saturation degree S indicates color close to the degree of spectrum colour.A kind of color, can regard certain spectrum colour as and white is mixed
The result of conjunction.Wherein ratio shared by spectrum colour is bigger, and the degree of color close to spectrum colour is just higher, and the saturation degree of color is also
Higher.Saturation degree is high, and color is then deep and gorgeous.The white light ingredient of spectrum colour is 0, and saturation degree reaches highest.Usual value range is
0%~100%, value is bigger, and color is more saturated.
Lightness V indicates bright degree, and for light source colour, brightness value is related with the brightness of illuminator；For object
The transmittance or reflectivity of body colour, this value and object are related.Usual value range is 0% (black) to 100% (white).
After far infrared imaging sensor 6 obtains thermal imaging, is handled by image scaling, original image is reduced in proportion
Then it is stacked to the lower right corner of nature rgb image, ultimately forms multidimensional image 8, multidimensional image 8 is enterprising in image display
Row display, the multidimensional image 8 had both remained the color of human eye habit, details, while from the dimension of black light, temperature being switched to
Visual image, it is significant to the monitoring of the occasions such as oil field, the electric power of remote districts.
The foregoing is merely the preferred embodiments of the invention, are not intended to limit the invention creation, all at this
Within the spirit and principle of innovation and creation, any modification, equivalent replacement, improvement and so on should be included in the invention
Protection scope within.
