Referring to fig. 1, the present embodiment provides a finger vein image capturing and identifying system, which includes: a first image sensor, a second image sensor, a memory, and an image recognizer; wherein the content of the first and second substances,

the first image sensor and the second image sensor are used for acquiring finger vein images of the target object, and the first image sensor and the second image sensor are located in different target areas. By way of example, in the embodiments of the present application, the target object includes, but is not limited to, a person suffering from a certain disease or diseases, or simply a disease patient. The first image sensor is arranged in a hospital information registration room, and the second image sensor is arranged on the self-service printing equipment. The hospital visit information registration room is a place where the visit information registration of the disease patient is performed when the disease patient first enters the hospital, the self-service printing device refers to a device or an instrument for printing a report on the disease patient, and the report which can be printed by the self-service printing device includes but is not limited to: a diagnostic report, an examination report; and the self-service printing equipment is respectively connected with the memory and the image recognizer. In the embodiment of the present application, the first image sensor and the second image sensor refer to image sensors in a vein recognizer, and the principle of acquiring images of finger veins may be as follows: by utilizing the characteristic that red blood cells in veins absorb specific near infrared rays, the near infrared rays irradiate the finger, and the image sensor senses light transmitted by the finger to acquire a vein image inside the finger, so that biological feature recognition is performed. When the near infrared rays are transmitted, the veins are highlighted on the image sensed by the image sensor, and muscles, bones and other parts of the finger are weakened, so that a clear vein blood vessel image, namely a finger vein image, is obtained.

The memory is used for storing finger vein images and is respectively connected with the first image sensor and the second image sensor. The finger vein images that can be stored in the memory include, but are not limited to: the first image sensor is used for acquiring finger vein images of the disease patients in a hospital visit information registration room, and the second image sensor is used for acquiring finger vein images of the disease patients in a self-service printing device. As an example, the memory in the embodiment of the present application may be located in a Hospital Information System HIS (Hospital Information System, HIS for short), a Laboratory Information Management System LIS (LIS for short), a Picture archiving and communication System PACS (PACS for short), and/or a Radiology Information Management System RIS (RIS for short).

The image recognizer is used for comparing and recognizing finger vein images and is connected with the memory. The image recognizer in the embodiment of the present application may compare the recognized finger vein images, including but not limited to: the digital vein image of the disease patient collected by the first image sensor at the hospital visit information registration room is stored in the memory, and the digital vein image of the disease patient collected by the second image sensor at the self-service printing device is stored in the memory. By way of example, the image recognizer in the embodiment of the present application is an existing device, apparatus and/or instrument capable of performing comparison recognition on two finger vein images, and the present embodiment merely performs comparison recognition on finger vein images by using an existing finger vein image comparison recognition device, apparatus and/or instrument, without improving or changing the comparison recognition principle. For example, taking a certain existing finger vein image comparison and recognition device as an example, the process of performing comparison and recognition on two finger vein images may be: acquiring two finger vein images to be compared, wherein the two finger vein images to be compared are respectively a finger vein image acquired by a first image sensor and a finger vein image acquired by a second image sensor, and the finger vein images to be compared are single-channel images. And carrying out image channel fusion on the two finger vein images to be compared to obtain a two-channel target finger vein image to be compared. Inputting the target finger vein image to be compared into a feature extractor, and extracting the feature vector of the target finger vein image to be compared through the feature extractor, wherein the feature extractor is obtained by adopting a two-channel convolutional neural network for training. Inputting the feature vectors of the target finger vein images to be compared into a two-classification device to obtain two-classification results; and determining whether the two finger vein images to be compared are from the same finger or not according to the classification result. If the value obtained by the classification result is 0, determining that the two finger vein images to be compared are from the same finger; and if the value obtained by the classification result is 1, determining that the two finger vein images to be compared are not from the same finger. Namely, the two classification results are 0, which means that the two finger vein images to be compared come from the same finger, and the two classification results are 1, which means that the two finger vein images to be compared do not come from the same finger.

In an exemplary embodiment, the system for capturing and identifying images of finger veins further comprises a display connected with the image identifier, and the display is used for displaying the comparison and identification results of the images of finger veins. For example, when the comparison and identification are successful, that is, when the result of the classification is 0, the word such as "successful identification" is displayed; when the comparison and identification fail, namely when the result of the classification is 1, characters such as 'identification fail, please re-identify' and the like are displayed.

According to the above description, the finger vein image acquisition and identification system of the present invention can be connected to the existing hospital information system HIS, laboratory information management system LIS, medical image archiving and communication system PACS, radiology information management system RIS, and the like. When a disease patient enters a hospital for the first time, a finger vein image of the disease patient is collected in a hospital visit information registration room, and then the collected finger vein image is used as an identification code of the disease patient in the hospital or other medical system. Meanwhile, because the finger vein images of each person are different, the vein images of different fingers of the same person are different, and the vein shape of a healthy adult does not change any more. Therefore, the finger vein image can be used as the identification code of the disease patient, and compared with the existing identification code of the disease patient, which is the bar code paper and the treatment card, the finger vein image has uniqueness and stability, and the risk of damage, loss and the like is avoided. In addition, after the patients with diseases have been treated, the patients with diseases can enter finger vein images again in departments or halls equipped with self-service printing equipment, then compare and identify the finger vein images entered at the current moment with the finger vein images entered in the hospital treatment information registration room by using the image identifier, and judge whether the images are the same finger according to the comparison and identification results of the image identifier. When the finger vein images input twice come from the same finger, the corresponding detection report and diagnosis report can be printed by the disease patient after the comparison and identification are successful, so that the identity of the disease patient can be identified by acquiring, comparing and identifying the finger vein images of the disease patient when the self-service equipment cannot identify the fingerprint of the disease patient, the waiting time for the disease patient to see a doctor is shortened, the inquiry progress of the disease patient to see a doctor is improved, and the diagnosis efficiency of a hospital is improved. Moreover, since the venous blood vessels are hidden inside the fingers, the vein blood vessels are extremely difficult to copy and steal, and compared with other technologies which utilize the characteristics of the human body outside the human body, the vein blood vessels are higher in safety. Meanwhile, the vein can sense the blood flow and blood pressure conditions in the finger, and the living body detection can be carried out in the identification process.
