  遠赤外線画像を用いたヒトの口呼吸の非接触計測の実現に向けて，基礎検討および技術課題の明確化を行った． はじめに，申請者らが考案した流速の推定法について，精度の向上を試みた．申請者らはこれまでに，呼吸部位の温度の時間変化を用いて流速の瞬時値を定量的に推定する手法を考案している．しかしながら，この手法を本研究への応用するためには，遠赤外線画像より取得した温度のノイズ，および，個人差による推定精度の低下を改善する必要があることが判明した．そこで，移動平均を用いた平滑化フィルタの導入，および，最大値・最小値を用いた正規化処理により，これらの影響を軽減する方法の考案を行った． 次に，鼻呼吸を対象に，呼吸部位における気温の変化速度から呼気および吸気の流速を推定する実験を，呼吸の仕方を変えた5種類の実験条件(通常呼吸，強い呼気・通常吸気，弱い呼気・通常吸気，通常呼気・強い吸気，通常呼気・弱い呼気)の下で行った．その結果，考案した手法は，申請者らの従来法よりも推定精度が平均で約5%向上することが確認された．さらに，遠赤外線画像より取得した呼吸部位の温度から，呼気および吸気における気温を推定する実験を，同様の実験条件の下で行った．その結果，考案した手法は，申請者らの従来法よりも推定精度が平均で約12%向上することが確認された．一方，考案した手法を口呼吸へ応用するためには，遠赤外線画像から抽出する口腔部分の具体的な領域，呼吸中の口の形状の影響などについて，さらなる検討が必要であることが判明した．

  本研究では、プライバシー保護の観点から監視カメラが利用できない療養環境において、ベッドや患者の着衣などに装着するセンサー、身体に装着するウェアラブルセンサーからの出力データを用い、事故の予防やせん妄発症の予兆検知を機械学習により行うことを目的とする。 ベッド面の面圧分布センサー上での10数名の実験参加者を対象として、寝返り、起き上がり動作の測定実験を実施した。動作前後の重心位置の左右および上下方向の差、動作中の左右および上下の速度ベクトル、および加速度ベクトルを入力とし、ビデオから判別した寝返り、起き上がり動作をラベルとした機械学習によりこれらの動作を識別できる可能性を得ている。 夜間覚醒やせん妄発症に伴う自律神経活動バランスの変化や乱れを検出するためには、心電図拍動間隔時系列の周波数情報が必要となる。一方でスマートウォッチやベッド面装着センサーから得られる心拍情報は、心電図拍動間隔時系列と比較して時間分解能が低いため、センサーから得られる心拍情報の周波数解析は自律神経活動バランス評価に適さない。スマートウォッチで測定される心拍情報と心電図の同期測定を行い、心電図R-R間隔から算出される自律神経活動バランス指標をスマートウォッチの心拍情報から算出される時間領域指標を用い、機械学習による回帰モデルを作成した。これによりスマートウォッチやベッド面装着型バイタルセンサーを活用した高精度の自律神経活動バランス評価により、夜間覚醒や自律神経活動バランスの乱れの早急な検知への応用が可能となる。
• Noncontact measurement of flow velocity and flow rate in human breathing by using Far Infrared Imaging

  Japan Society for the Promotion of Science：Grants-in-Aid for Scientific Research

  Date (from‐to) : 2018/04 -2021/03 

  Author : Hanawa Dai

   

  In this research, we studied the feasibility of a method for non-contact measurement of quantitative flow velocity and flow rate in human breathing by using far-infrared imaging. We first compared the air temperature, flow velocity, and surface temperature in the nasal cavity during human nasal breathing by conducting experiments. We next proposed a method for estimating the flow velocity from the air temperature and the surface temperature based on the experimental results. As a result, we found that the quantitative flow velocity in nasal breathing can be estimated in a non-contact manner by using far-infrared images.

  In this research, we studied on noncontact and simultaneous measurement of human breathing for multiple users, by using far infrared (FIR) imaging. We first proposed methods to extract the regions including nasal cavity or oral cavity from FIR images which was capturing a single user's face. We next proposed methods to estimate qualitative strength of flow velocity in nasal breathing and oral breathing. Finally, we showed that noncontact and simultaneous measurement of human breathing for multiple users can be realized by using the above two methods.
• Study on Non-contact Measurement of Human Breathing by using Far Infrared Imaging

  Japan Society for the Promotion of Science：Grants-in-Aid for Scientific Research Grant-in-Aid for Young Scientists (B)

  Date (from‐to) : 2012/04 -2014/03 

  Author : DAI Hanawa

   

  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.
