Abstract
The utility model discloses a hand-held camera system comprising a flat computer and host machine mutually connected, wherein the host machine comprises at least ten kinds of LED lamps with visible light band colors, a pick-up head, and a PCB plate respectively connected with the LED lamps and the pick-up head, and the LED lamps are uniformly arranged around a lens of the pick-up head. The hand-held camera system uses multi-color LEDs to carry out color separation photograph, then the flat computer is used to control the pick-up head for shooting, the camera system is light in weight and small in size, can be operated by one person in field, and is suitable for shooting fingerprints in a criminal case field.
Description
Technical field
The utility model relates to colour photography and multispectral processing technology field, particularly relates to a kind of hand-hold type camera system.
Background technology
At present to take pictures the most frequently used be the colour photography technology to fingerprint, and it adopts alternative light source, and such as 16 wave band light sources, the monochromatic visible light that sends different wave length shines on the fingerprint, and common every kind of monochromatic bandwidth is 30-40nm.The same with irradiation light or when be inverse when background colour, background will be dimmed or be brightened, and causes the contrast increase of fingerprint and background, just can clearly photograph fingerprint.Criminal technique personnel constantly change the color of light, take multiple pictures, select at last best one of effect wherein.
Use camera to take pictures in the aforesaid prior art, the technical staff must operate alternative light source on one side, operate camera on one side, if reconnoitre can be very difficult for people, therefore also have at present with alternative light source and digital camera head combine integrated.And, colour photography has great drawback in fingerprint is taken: 1, in the actual case, background below the fingerprint is color a lot (being commonly called as colored background) often, such as color page. in this case, the alternative light source effect can not got well certainly, because which kind of monochromatic light all can only be eliminated homochromy background, remaining heterochromatic background has just stayed, so any photo is some local bluring all, some place is clear.Even 2 backgrounds are monochromatic, if approach with the fingerprint color.Because difference is too little, shooting effect can not got well.Most typical case is that the blood fingers and palms line under the dark flower background is clapped not get off, this the name of the game is that the monochromatic picture that any one wave band light source is filmed all only comprises the part useful information, but existing product is had no idea the informix of multiple pictures, and in most cases final effect naturally can be not fine.This is the defective on the principle, and existing mode can't solve.
Light spectrum image-forming is to record tested object (ultraviolet, visible light, infrared band) monochromatic reflected image of a plurality of narrow wave bands or fluoroscopic image (tested object is as far as possible motionless) in certain spectral region by spectrum imaging device, by algorithm these images are carried out integrated treatment more subsequently, thereby reach the purposes such as enhanced contrast.Since its processing to as if a plurality of images, amount of information is very large, be single image a lot of doubly, so treatment effect is more much better than single image.This technology has been brought into play great function in fields such as military affairs, mineral products remote sensing, biology.This type of multispectral treatment system is utilized the spectrum algorithm more, and the informix utilization with multiple pictures has improved the fingerprint shooting effect greatly, but this kind small product size is very large, its core devices: the liquid crystal turnable filter is quite fragile, therefore is only suitable for use for laboratory.And the on-the-spot fingerprint more than 80% of public security can't take off, and also just cannot take back laboratory treatment.This kind product is import, and is very expensive.

Description of drawings
Fig. 1 is system configuration schematic diagram of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, the utility model provides a kind of hand-hold type camera system, comprises interconnective panel computer 1 and main frame 2, and described panel computer 1 is connected by the usb data line with the pcb board of main frame 2.Described main frame 2 comprises the LED lamp of at least ten kinds of visible light wave range colors, the CMOS camera that pixel count is 2M at least and the pcb board 2 that is connected with described LED lamp, CMOS camera respectively, and described LED lamp is evenly arranged around the micro-lens of described camera.The LED lamp of every kind of visible light wave range color has 4 at least, consistent in order to guarantee each LED lamp luminosity, the LED lamp is connected in series one by one, more than 10 kinds the LED lamp of color such as: 700nm-peony, 660nm-is red, 630nm is orange, 605nm-is amber, 585nm-is yellow, 570nm-light greenish blue, the pure green of 525nm-, 505nm-are dark green/blue-green, 500nm-light green cyan, 475nm-celeste blue, 450nm-pure blue, 444nm-navy blue.
Described pcb board is provided with single-chip microcomputer, LED control chip and the USBHUB chip that connects successively.Described single-chip microcomputer is C8051F320.Described LED control chip is RTF1113.
Micro-lens wherein is camera lens that be fit to take fingerprint, requires lightweightly, and volume is little, and it is little to distort, and fingerprint image is full of the CMOS camera substantially.Because fingerprint varies, so the camera lens need can adjusting focal length.Because be hand-held product, volume can not be excessive, therefore consider to use small plate machine camera lens.
Operation principle is as follows: the single-chip microcomputer in the PCB circuit board receives the instruction of indicating acquisition of image data from panel computer by the usb data line, according to this instruction control LED control chip, so that the LED control chip is controlled light on and off and the light and shade of LED lamp, colour photography is carried out in realization, then control camera and carry out IMAQ, the speed that gathers can be very low, such as 1 second 5 frame, single-chip microcomputer carries out many monochromatic fingerprint images to obtain an image after the multispectral processing after gathering, and by the usb data line image is passed to panel computer.
