Abstract:

Abstract Vein display device can significantly increase the success rate of intravenous injection. However, traditional vein display devices only contain near-infrared image information, which inevitably loses skin color information. In this article, a binocular microlens was fabricated by micro-fabrication technology. Then, a smart binocular microlens imaging system is set up. By this system, the near-infrared image with venous distribution and visible light image with actual skin color can be obtained simultaneously. In addition, an improved image fusing algorithm is proposed. The image fusing result shows that the venous details can be clearly shown and the background color of the hand also can be well preserved. Therefore, the proposed scheme can provide more real vein information. As the smart structure of the binocular microlens, the dual-bands microlens imaging system has the potential for miniaturization and could integrate with intelligent glasses for assisting intravenous injection
