Embodiment Construction

[0036] The present invention will be further described below in conjunction with accompanying drawing.

[0037] Such as figure 1 The shown human superficial vein three-dimensional reconstruction device based on binocular stereo vision includes two infrared cameras 1, two filters 3, a near-infrared light source 4, a USB data cable, a synchronous trigger module and a computer. Two infrared cameras 1 are arranged in parallel, and are respectively connected to the computer through USB data cables, and the collected images are transmitted to the computer. The synchronous triggering module is respectively connected with the two infrared cameras 1 and the computer, and the synchronous triggering module receives the control instructions from the computer to control the two infrared cameras 1 to collect image data synchronously. The lenses 2 of the two infrared cameras 1 all face downward and are located on the same horizontal plane. The two filters 3 are respectively arranged on the...

Abstract

The invention discloses a human body superficial layer vein three-dimensional reconstruction device and method based on binocular stereoscopic vision. The device comprises two infrared cameras, two filters, near-infrared light sources, USB data lines, a synchronous triggering module and a computer. The two infrared cameras are arranged in parallel and connected with the computer through the USB data lines. The synchronous triggering module is connected with the two infrared cameras and the computer. Lenses of the two infrared cameras are located downwards and located on the same horizontal plane. The two filters are correspondingly arranged on the incident light sides of the two lenses. The brightness of the near-infrared light sources is adjustable, and the near-infrared light sources are arranged below the two infrared cameras. The problem that due to the fact that patient veins are not salient, the failure rate in clinical vein puncture is high is solved.

Description

technical field [0001] The invention belongs to medical auxiliary equipment, in particular to a device and method for three-dimensional reconstruction of human superficial veins based on binocular stereo vision. Background technique [0002] Infrared imaging of veins plays an important role in medical assistance and biometric identification. In medical treatment, vein imaging technology has been developed rapidly. Relevant data show that: the success rate of normal adult venipuncture for the first time is 73%; the failure rate of the first two venipuncture for children is 58%; for most people, the "missing needle" during venipuncture The probability of venipuncture is 23-28%. Since there are many superficial subcutaneous tissues in the human body, it will be affected by many factors such as blood vessel depth, fat layer thickness, and skin pigment content during venipuncture. Personnel tend to have a lower success rate when puncturing. In the field of biometric identifica...
