, draw blood by human vein is injected medically, the medical procedure such as blood transfusion reach the purpose of curing illness.Some patients were is because fat is thicker, and the colour of skin is darker, and the reasons such as severe loss of blood cause blood vessel clearly to present, and have caused " dropped stitch ", and medical obstacles such as " puncture failures " has brought inconvenience for doctor and patient.At present in the clinic diagnosis process, helping in the curative activity rapidly and accurately, the position patient vein blood vessel is a very crucial job.
The reproduction process of hand back vein needs each module cooperative work to finish.At first, the collection of hand back vein image is especially crucial, utilizes venae subcutaneae blood vessel and surrounding tissue to the characteristics that the absorbance of near infrared light there are differences, and adopts near-infrared active illumination, the good vein image of reflective imaging technique acquisition contrast; Secondly, adopt image processing techniques that the vein image that gathers is carried out pretreatment, detailed process generally comprises the processes such as image normalization, image segmentation, quality analysis, figure image intensifying, and the vein blood vessel in the image is highlighted; The image that adopts at last the mode of Projection Display to process accurately projects acquisition zone with visible light, and the vein image of demonstration has the characteristics of high brightness, high evenness.
Still there are many deficiencies in present vein image acquisition and the Display Technique.Chinese patent CN101799862, a kind of portable opisthenar vein biological features collecting and identifying device is disclosed, adopt the mode of annular near-infrared LED array the back of the hand acquisition zone that throws light in this patent, by experiment checking, this patent can't obtain uniformly illumination at acquisition zone, has affected the contrast quality of images acquired.Chinese patent CN102379699, a kind of method and vein blood vessel puncture scope that improves body surface vein blood vessel definition disclosed, the method has adopted the three-color LED light source to replace luminous switch controller and time interval controls device, and the shortcoming of this patent is complicated structure, and cost is higher.
Summary of the invention
The objective of the invention is to overcome the prior art above shortcomings, a kind of acquisition and display equipment of hand back vein image is provided, be used for the vein blood vessel position of the accurate position patient of clinic diagnosis assist personnel.
The acquisition and display equipment of hand back vein image provided by the invention, by near-infrared image acquisition module (1), near-infrared lighting module (2), image processing module (3) and visible light Projection Display module (4) form, and modules all is integrated in one; Described near-infrared image acquisition module (1) and near-infrared lighting module (2) collaborative work, the collecting work that is used for the hand back vein image, at first, the near-infrared lighting module carries out Uniform Illumination to the acquisition zone of hand back vein, and the near-infrared image acquisition module carries out collecting work to the venae subcutaneae tissue of acquisition zone simultaneously; Described image processing module (3) carries out the real-time pretreatment to the image that gathers, and vein blood vessel can be highlighted clearly; Vein image after described visible light Projection Display module (4) will be processed accurately projects to acquisition zone, so that the hand back vein blood vessel can clear reproduction.
Described near-infrared image acquisition module adopts near-infrared object lens and Near Infrared CCD or the CMOS composition that is applicable to wavelength 760nm～3000nm.Placed special-purpose infrared fileter before the described near-infrared image acquisition module, the information such as filtering visible light are on the impact of image detail.
The near-infrared LED that described near-infrared lighting module employing wavelength is 850nm is light source, and has placed two fourier lenses to consist of the modes of cola illumination, reaches the purpose of shining equably the back of the hand acquisition zone.
Described image processing module extracts the vein image that the near-infrared acquisition module gathers, and then image is carried out pretreatment, and preprocessing process comprises the processes such as image normalization, image segmentation, quality analysis, figure image intensifying, and vein blood vessel is highlighted;
Described visible light Projection Display module is extracted the vein image that image processing module was processed, and vein image is projected to the back of the hand acquisition zone.Visible light Projection Display module is that the green glow high-power LED light source of 555nm, equal optical wand, condenser lens, plane mirror, LCD liquid crystal board and projection objective form by wavelength; Projection objective adopts from the axle design so that projecting light path and collection light path are separated.
Advantage of the present invention and beneficial effect:
The acquisition and display equipment of a kind of hand back vein image disclosed by the invention, in the near-infrared lighting module, adopt the method for cola illumination assist and obtained preferably hand back vein image of contrast quality, improved the reliability of hand back vein clear picture reproduction from collection terminal; In addition, the visible light projection module has adopted from the axle design projection objective, is convenient to make projecting light path and gather light path separately with the most succinct frame for movement.The present invention is the new medical equipment that a kind of clinical result of use is good, real-time, simple in structure, cost is low.
Description of drawings
Fig. 1 is the acquisition and display equipment main modular schematic diagram of a kind of hand back vein image of the present invention.
Fig. 2 is the acquisition and display equipment light path schematic diagram of a kind of hand back vein image of the present invention.
Among the figure, 1-near-infrared acquisition module, 2-near-infrared lighting module, 3-image processing module, 4-visible light Projection Display module, 5-near-infrared LED, 6-fourier lense group, 7-Near Infrared CCD or CMOS, 8-near-infrared object lens, 9-green light LED, 10-optical tunnel, 11-condenser lens, 12-plane mirror, the 13-LCD liquid crystal board, 14-projection lens.
The specific embodiment:
The present invention is described further below in conjunction with embodiment and accompanying drawing, but should not be construed as protection domain of the present invention of task limits.
As shown in Figure 1, the acquisition and display equipment of hand back vein image of the present invention, it is by near-infrared image acquisition module 1, near-infrared lighting module 2, image processing module 3, visible light Projection Display module 4 forms, and modules all is integrated in one.
Wherein, near-infrared image acquisition module 1 is comprised of the near-infrared object lens 8 that are applicable to wavelength 760nm～3000nm and Near Infrared CCD or CMOS7;
Near-infrared lighting module 2 is that near-infrared LED 5 and the fourier lense group 6 of 850nm forms by wavelength;
Visible light Projection Display module 4 is that high power green light LED 9, optical tunnel 10, Quasi-straight light-focusing mirror 11, plane mirror 12, LCD liquid crystal board 13 and the projection lens 14 of 555nm forms by wavelength.
