Paper Abstract

Venipuncture is the most common way of all invasive medical procedures. A vein display system can make vein access easier by capturing the vein information and projecting a visible vein image onto the skin, which is correctly aligned with the subject’s vein. The existing systems achieve correct alignment by the design of coaxial structure. Such a structure causes complex optical and mechanical design and big physical dimensions inevitably. In this paper, we design a stereovision- based vein display system, which consists of a pair of cameras, a DLP projector and a near-infrared light source. We recover the three-dimensional venous structure from image pair acquired from two near-infrared cameras. Then the vein image from the viewpoint of projector is generated from the three-dimensional venous structure and projected exactly onto skin by the DLP projector. Since the stereo cameras get the depth information of vessels, the system can make sure the alignment of projected veins and the real veins without a coaxial structure. The experiment results prove that we propose a feasible solution for a portable and low-cost vein display device.
