Embodiment Construction
[0044] The present invention will be described in further detail below in conjunction with specific embodiments.
[0045] 1. Use the JAI-AD080CL visible light / near-infrared synchronous camera to capture images of the arm. The camera simultaneously captures the visible / near-infrared spectrum of arm images, with visible and near-infrared light passing through a single lens and entering two photosensitive chips. Among them, the first chip uses Bayer color technology, which only acquires visible light, that is, conventional images; the second chip is a monochromatic near-infrared imaging chip, and under the irradiation of a near-infrared light source, the near-infrared skin image taken by it can be See where the veins are; the two images are perfectly in sync. In order to improve the positioning accuracy of vein location, this example first collects images of the inner forearm of 20 people (each person has 1 group of visible light / near-infrared images, a total of 20 groups), and ...
