我们提出了一种使用红、绿、蓝 (RGB) 相机进行静脉顺应性非接触式成像的技术。血液浓度的任何变化都是根据皮肤的 RGB 图像来估计的，并根据该变化计算回归公式。静脉顺应性是从回归公式的微分形式获得的。对人类受试者的体内实验证实，所提出的方法确实区分了个体之间的静脉顺应性。另外，通过对每个像素执行上述过程来获得静脉顺应性的图像。因此，我们可以在不与传感器物理接触的情况下测量静脉顺应性，并从生成的图像中观察静脉顺应性的空间分布，这与静脉的分布相关。
We propose a technique for non-contact imaging of venous compliance that uses the red, green, and blue (RGB) camera. Any change in blood concentration is estimated from an RGB image of the skin, and a regression formula is calculated from that change. Venous compliance is obtained from a differential form of the regression formula. In vivo experiments with human subjects confirmed that the proposed method does differentiate the venous compliances among individuals. In addition, the image of venous compliance is obtained by performing the above procedures for each pixel. Thus, we can measure venous compliance without physical contact with sensors and, from the resulting images, observe the spatial distribution of venous compliance, which correlates with the distribution of veins.
