Study on Non-contact Measurement of Human Breathing by using Far Infrared Imaging

本文研究了一种利用远红外图像对人体呼吸进行非接触测量的方法。本文首先提出了一种提高远红外图像中鼻腔位置检测精度的方法。接下来，我们从头部姿势和呼吸方式的角度实验评估了我们的方法的鲁棒性。基于这些结果，所提出的方法的有效性，其特点是明确的。最后，我们讨论了它的适用性的估计系统所造成的身体按摩。实验结果表明，基于远红外成像的非接触式、微约束式人体呼吸测量方法是可行的。

In this research, we studied a method for non-contact measurement of human breathing by far infrared images. We first proposed a method of improving on the accuracy of detecting nasal cavity location in far infrared images. Next, we experimentally evaluated robustness of our method from viewpoints of head posture and the way of breathing. Based on these results, effectiveness of the proposed method, and its characteristics were clarified. We finally discussed its applicability to the system for estimating effects caused by body massage. From these results, we showed the feasibility of the measurement of human breathing by non-contact manner and slight restraining, based on far-infrared imaging.
