Description

A display system for color vein glasses

technical field

The invention relates to a vein display device, in particular to a display system of colored vein glasses.

Background technique

Intravenous injection has long been widely used in the medical field as the most direct and effective way of drug delivery. But the key to the implementation of this medical technology is to try to find the blood vessels of the human body first, so that the blood vessels can be punctured with needles for subsequent treatment. At present, clinical positioning of blood vessels mainly depends on the experience of medical staff. However, this often encounters difficulties in practice. For example, for obese patients, edema patients, newborn infants, children, etc., even experienced nurses often have difficulty in ensuring accurate operation during venipuncture. Therefore, how to quickly and accurately find blood vessels in patients is very important.

It can be seen that the subcutaneous vein display device has great application value for medical diagnosis and intravenous injection. In the past ten years, the research on vein imaging technology has been very rapid, and the results have emerged one after another. According to the irradiation mode of the light source, the existing vein display equipment can be divided into two types: transmissive system and reflective system.

However, the traditional transmissive vein display system generates a huge amount of heat, which not only makes it difficult to dissipate heat, but may even cause harm to the human body. In actual application of the traditional reflective vein display system, the doctor needs to perform the acupuncture operation while looking at the screen, which will bring some inconvenience to the doctor, so the scope of application is limited.

In addition, the traditional vein display system highlights the meridians of the human body by acquiring near-infrared images of parts of the human body and using image processing technology. This method is entirely based on near-infrared image data, and the displayed image is close to a black and white image, which loses other color and detail information of the epidermis. The overall effect is unreal. In addition, because the needle appears as a black image under near-infrared light, there will be visual interference with the black pattern displayed by the vein, which will affect the doctor's judgment. Therefore also greatly hindered the application breadth of this product.

Contents of the invention

The purpose of the present invention is to provide a color vein glasses display system for the defects in the prior art, which can maintain the original color and detail information of the epidermis under the premise of accurately displaying the distribution of veins, and realize the observation with human eyes as a whole.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic structural diagram of a display system for colored vein glasses provided by an embodiment of the present invention.

Detailed ways

The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in FIG. 1 , an embodiment of the present invention provides a display system for colored vein glasses. The system includes a vein image processing device 2 and smart glasses 1 connected to each other, and a high-definition camera, a near-infrared light source 13 and an imaging device 14 are installed on the smart glasses 1 .

Specifically, there are two high-definition cameras, including a visible light camera 11 and a near-infrared camera 12. The lens of the visible light camera 11 is a near-infrared cut-off filter, and the lens of the near-infrared camera 12 is a visible light cut-off filter; The camera 11 and the near-infrared camera 12 are respectively connected to the input ends of the vein image processing device 2; after the vein image processing device 2 fuses the images input by the visible light camera 11 and the near-infrared camera 12, the fused image is output to the imaging system. Device 14 ; the imaging device 14 displays the image output by the vein image processing device 2 on the lens 15 of the smart glasses 1 .

The near-infrared light source 13 is composed of a plurality of near-infrared LED lamps with a wavelength of 800nm to 900nm. The near-infrared light source 13 is evenly distributed around the high-definition camera so that the light intensity of the irradiation is uniform. There is no need to add additional visible light sources, and the daily indoor lighting can meet the camera requirements.

Among the two high-definition cameras, the near-infrared light camera 12 is equipped with a visible light cut-off filter, so only near-infrared light can pass through and be imaged by the camera. Oxyhemoglobin in the blood vessel absorbs the near-infrared light strongly, and the reflection at the blood vessel is weak Therefore, the near-infrared light camera 12 equipped with a visible light cut-off filter can sense different information of veins and skin, and highlight vein information. The visible light camera 11 is equipped with a near-infrared cut-off filter, and the camera can only sense information of visible light, and is used for sensing detailed information such as skin color and texture. Since the images obtained by the two high-definition cameras need to be synthesized in the later stage, in terms of layout, the two cameras should be arranged in parallel and close to each other, and arranged parallel and side by side between the two lenses 15 of the smart glasses 1, so as to minimize the asymmetrical part of the image; Avoid excessive range difference and poor field of view in the acquired image due to the position gap between the two.

The vein image processing device 2 includes a near-infrared image processing module, a visible light image processing module and an image fusion module; The image is processed to enhance the details of human veins in the image; the visible light image processing module is connected with the visible light camera 11, and is used to process the visible light image obtained by the visible light camera 11 so that it is close to the real color; the image fusion module is connected with the visible light camera 11 The near-infrared image processing module is connected with the visible light image processing module, and is used to fuse the images processed by the near-infrared image processing module and the visible light image processing module.

When in use, the vein image processing device 2 first extracts the images acquired by the two high-definition cameras, and then performs image processing on the images of the two high-definition cameras. For near-infrared images, the near-infrared image processing module mainly enhances vein details through filter enhancement, contrast enhancement, denoising and other processing methods; for visible light images, the visible light image processing module mainly uses color tuning to make it similar to the real color. Finally, the image fusion module uses an image fusion algorithm combining principal component analysis and bilateral filtering to fuse the near-infrared light image and the visible light image. The fused image can simultaneously highlight the vein distribution and maintain the background skin color.

Since image processing requires a large amount of calculations, the relevant processing units need to have certain CPU and GPU computing capabilities, so the vein image processing device 2 adopts an external connection mode and is connected to the smart glasses 1 through a data line, so that the glasses themselves can The reduction in weight can also ensure the speed of image processing and real-time display of images. In addition, the vein image processing device 2 can also provide power support for the entire glasses system.

Further, the imaging device 14 has a variety of specific design options, it can be an intelligent display integrated with the lens 15 of the smart glasses 1, and the image output by the vein image processing device 2 is directly displayed on the lens 15; it can also be The micro-projection device projects the image output by the vein image processing device 2 onto the lens 15. In the embodiment of the present invention, two micro-projection devices are used, and the two micro-projection devices are respectively installed on both sides of the frame of the smart glasses 1. On the bracket on the side, project toward the eyeglass 15 from the side. In practical applications, existing smart glasses integrated with imaging devices can also be directly used on the market, saving the cost of separate development; such as Google Glass smart glasses produced by Google or Epson BT-200 smart glasses produced by Epson or Smart glasses with a similar projection function. The lenses of the above two smart glasses are transparent and will not hinder the normal vision of the user.

The present invention provides a color vein glasses display system. Two cameras are installed on the smart glasses, one of which is equipped with a near-infrared cut-off filter, and the other is equipped with a visible light cut-off filter. The two cameras simultaneously acquire visible light images respectively. and near-infrared images; the two images are fused, and the fused image can simultaneously highlight the vein distribution and maintain the background skin color; at the same time, use the imaging device to directly project the processed color vein image onto the glasses to achieve wearable Type vein display system.

The present invention not only solves the discomfort caused by the doctor needing to look at the screen while performing the acupuncture operation; it can also effectively overcome the problems of color distortion in the traditional vein display scheme, and can maintain accurate vein distribution under the premise of accurately displaying the vein distribution. The original color and detailed information of the epidermis achieve a display effect similar to that observed by the human eye as a whole, which is more conducive to assisting medical staff to find the accurate location of blood vessels. Moreover, through image synthesis, the color details of the needle are preserved, and form a true contrast with the black vein, which solves the disadvantage of inconspicuous contrast between the needle image and the vein image. The present invention can directly observe veins through glasses, and perform acupuncture operation, and has stronger operability; therefore, it is more conducive to the wide application of products.

The above-mentioned embodiments only express several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but should not be construed as limiting the patent scope of the present invention. It should be pointed out that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
